+\xsection{cl-2.xx}{NASM 2 Series}
+The NASM 2 series supports x86-64, and is the production version of NASM
+since 2007.
+\xsubsection{cl-2.15}{Version 2.15}
+ \item{The state of warnings can now be saved and restored via
+ the \code{[WARNING PUSH]} and \code{[WARNING POP]} directives.
+ See \nref{asmdir-warning}}.
+\xsubsection{cl-2.14.03}{Version 2.14.03}
+ \item{Suppress nuisance "\code{label changed during code
+ generation}" messages after a real error.}
+\xsubsection{cl-2.14.02}{Version 2.14.02}
+ \item{Fix crash due to multiple errors or warnings during the code
+ generation pass if a list file is specified.}
+\xsubsection{cl-2.14.01}{Version 2.14.01}
+ \item{Create all system-defined macros defore processing command-line
+ given preprocessing directives (\code{-p}, \code{-d}, \code{-u}, \code{--pragma},
+ \code{--before}).}
+ \item{If debugging is enabled, define a \code{\_\_DEBUG\_FORMAT\_\_} predefined
+ macro. See \nref{dfmtm}.}
+ \item{Fix an assert for the case in the \code{obj} format when a \code{SEG}
+ operator refers to an \code{EXTERN} symbol declared further down in the
+ code.}
+ \item{Fix a corner case in the floating-point code where a binary, octal
+ or hexadecimal floating-point having at least 32, 11, or 8 mantissa
+ digits could produce slightly incorrect results under very specific
+ conditions.}
+ \item{Support \code{-MD} without a filename, for \code{gcc} compatibility.
+ \code{-MF} can be used to set the dependencies output filename.
+ See \nref{opt-MD}.}
+ \item{Fix \code{-E} in combination with \code{-MD}. See \nref{opt-E}.}
+ \item{Fix missing errors on redefined labels; would cause convergence
+ failure instead which is very slow and not easy to debug.}
+ \item{Duplicate definitions of the same label \emph{with the same value} is now
+ explicitly permitted (2.14 would allow it in some circumstances.)}
+ \item{Add the option \code{--no-line} to ignore \code{\%line} directives in the
+ source. See \nref{opt-no-line} and \nref{line}.}
+\xsubsection{cl-2.14}{Version 2.14}

+ \item{Added the \code{--gprefix}, \code{--gpostfix}, \code{--lprefix}, and
+ \code{--lpostfix} command line options, to allow command line base symbol
+ renaming. See \nref{opt-pfix}.}
+ \item{Allow label renaming to be specified by \code{\%pragma} in addition to
+ from the command line. See \nref{mangling}.}
+ \item{Supported generic \code{\%pragma} namespaces, \code{output} and \code{debug}.
+ See \nref{gen-namespace}.}
+ \item{Added the \code{--pragma} command line option to inject a \code{\%pragma}
+ directive. See \nref{opt-pragma}.}
+ \item{Added the \code{--before} command line option to accept preprocess
+ statement before input. See \nref{opt-before}.}
+ \item{Added \code{AVX512} \code{VBMI2} (Additional Bit Manipulation), \code{VNNI}
+ (Vector Neural Network), \code{BITALG} (Bit Algorithm), and \code{GFNI} (Galois
+ Field New Instruction) instructions.}
+ \item{Added the \code{STATIC} directive for local symbols that should be
+ renamed using global-symbol rules. See \nref{static}.}
+ \item{Allow a symbol to be defined as \code{EXTERN} and then later
+ overridden as \code{GLOBAL} or \code{COMMON}. Furthermore, a symbol
+ declared \code{EXTERN} and then defined will be treated as \code{GLOBAL}.

+ limits. See \nref{opt-limit}.}
+ \item{Updated the \code{Codeview} version number to be aligned with \code{MASM}.}
+ \item{Added the \code{--keep-all} command line option to preserve output
+ files. See \nref{opt-keep-all}.}
+ \item{Added the \code{--include} command line option, an alias to \code{-P}
+ (\nref{opt-p}).}
+ \item{Added the \code{--help} command line option as an alias to \code{-h}
+ (\nref{syntax}).}
+ \item{Added \code{-W}, \code{-D}, and \code{-Q} suffix aliases for \code{RET}
+ instructions so the operand sizes of these instructions can be
+ encoded without using \code{o16}, \code{o32} or \code{o64}.}
+\xsubsection{cl-2.13.03}{Version 2.13.03}

+ \item{Support up to 16 characters in section names for \code{macho}
+ output format.}
+ \item{Fix missing update of global \code{BITS} setting if \code{SECTION}
+ directive specified a bit size using output format-specific
+ extensions (e.g. \code{USE32} for the \code{obj} output format.)}
+ \item{Fix the incorrect generation of VEX-encoded instruction when static
+ mode decorators are specified on scalar instructions, losing the
+ decorators as they require EVEX encoding.}
+ \item{Option \code{-MW} to quote dependency outputs according to Watcom
+ Make conventions instead of POSIX Make conventions. See \nref{opt-MW}.}
+ \item{The \code{obj} output format now contains embedded dependency file
+ information, unless disabled with \code{\%pragma obj nodepend}. See
+ \nref{objdepend}.}
+ \item{Fix generation of dependency lists.}
+ \item{Fix a number of null pointer reference and memory allocation errors.}
+ \item{Always generate symbol-relative relocations for the \code{macho64}
+ output format; at least some versions of the XCode/LLVM linker fails
+ for section-relative relocations.}
+\xsubsection{cl-2.13.01}{Version 2.13.01}
+ \item{Fix incorrect output for some types of \code{FAR} or \code{SEG}
+ references in the \code{obj} output format, and possibly other 16-bit
+ output formats.}
+ \item{Fix the address in the list file for an instruction containing a
+ \code{TIMES} directive.}
+ \item{Fix error with \code{TIMES} used together with an instruction which
+ can vary in size, e.g. \code{JMP}.}
+ \item{Fix breakage on some uses of the \code{DZ} pseudo-op.}
+\xsubsection{cl-2.13}{Version 2.13}
+ \item{Support the official forms of the \code{UD0} and \code{UD1} instructions.}
+ \item{Allow self-segment-relative expressions in immediates and
+ displacements, even when combined with an external or otherwise
+ out-of-segment special symbol, e.g.:
+extern foo
+mov eax,[foo - $ + ebx] ; Now legal
+ \item{Handle a 64-bit origin in NDISASM.}
+ \item{NASM can now generate sparse output files for relevant output
+ formats, if the underlying operating system supports them.}
+ \item{The \code{macho} object format now supports the
+ \code{subsections\_via\_symbols} and \code{no\_dead\_strip}
+ directives, see \nref{macho-ssvs}.}
+ \item{The \code{macho} object format now supports the \code{no\_dead\_strip},
+ \code{live\_support} and \code{strip\_static\_syms} section flags,
+ see \nref{machosect}.}
+ \item{The \code{macho} object format now supports the \code{dwarf} debugging
+ format, as required by newer toolchains.}
+ \item{All warnings can now be suppressed if desired; warnings not
+ otherwise part of any warning class are now considered its own
+ warning class called \code{other} (e.g. \code{-w-other}). Furthermore,
+ warning-as-error can now be controlled on a per warning class
+ basis, using the syntax \code{-w+error=}\emph{warning-class} and its
+ equivalent for all other warning control options. See \nref{opt-w}
+ for the command-line options and warning classes and
+ \nref{asmdir-warning} for the \code{[WARNING]} directive.}
+ \item{Fix a number of bugs related to AVX-512 decorators.}
+ \item{Significant improvements to building NASM with Microsoft Visual
+ Studio via \code{Mkfiles/msvc.mak}. It is now possible to build the
+ full Windows installer binary as long as the necessary
+ prerequisites are installed; see \code{Mkfiles/README}}
+ \item{To build NASM with custom modifications (table changes) or from the
+ git tree now requires Perl 5.8 at the very minimum, quite possibly
+ a higher version (Perl 5.24.1 tested.) There is no requirement to
+ have Perl on your system at all if all you want to do is build
+ unmodified NASM from source archives.}
+ \item{Fix the \code{\{z\}} decorator on AVX-512 \code{VMOVDQ*}
+ instructions.}
+ \item{Add new warnings for certain dangerous constructs which never ought
+ to have been allowed. In particular, the \code{RESB} family of
+ instructions should have been taking a critical expression all
+ along.}
+ \item{Fix the EVEX (AVX-512) versions of the \code{VPBROADCAST}, \code{VPEXTR},
+ and \code{VPINSR} instructions.}
+ \item{Support contracted forms of additional instructions. As a general
+ rule, if an instruction has a non-destructive source immediately
+ after a destination register that isn't used as an input, NASM
+ supports omitting that source register, using the destination
+ register as that value. This among other things makes it easier to
+ convert SSE code to the equivalent AVX code:
+addps xmm1,xmm0 ; SSE instruction
+vaddps ymm1,ymm1,ymm0 ; AVX official long form
+vaddps ymm1,ymm0 ; AVX contracted form
+ \item{Fix Codeview malformed compiler version record.}
+ \item{Add the \code{CLWB} and \code{PCOMMIT} instructions. Note that the
+ \code{PCOMMIT} instruction has been deprecated and will never be
+ included in a shipping product; it is included for completeness
+ only.}
+ \item{Add the \code{\%pragma} preprocessor directive for
+ soft-error directives.}
+ \item{Add the \code{RDPID} instruction.}
+\xsubsection{cl-2.12.02}{Version 2.12.02}
+ \item{Fix preprocessor errors, especially \code{\%error} and
+ \code{\%warning}, inside \code{\%if} statements.}
+ \item{Fix relative relocations in 32-bit Mach-O.}
+ \item{More Codeview debug format fixes.}
+ \item{If the MASM \code{PTR} keyword is encountered, issue a warning. This is
+ much more likely to indicate a MASM-ism encountered in NASM than it
+ is a valid label. This warning can be suppressed with \code{-w-ptr},
+ the \code{[warning]} directive (see \nref{opt-w}) or by the macro
+ definition \code{\%idefine ptr \$\%} (see \nref{selfref}).}
+ \item{When an error or a warning comes from the expansion of a multi-line
+ macro, display the file and line numbers for the expanded macros.
+ Macros defined with \code{.nolist} do not get displayed.}
+ \item{Add macros \code{ilog2fw()} and \code{ilog2cw()} to the \code{ifunc} macro
+ package. See \nref{ilog2}.}
+\xsubsection{cl-2.12.01}{Version 2.12.01}
+ \item{Portability fixes for some platforms.}
+ \item{Fix error when not specifying a list file.}
+ \item{Correct the handling of macro-local labels in the Codeview debugging format.}
+ \item{Add \code{CLZERO}, \code{MONITORX} and \code{MWAITX} instructions.}
+\xsubsection{cl-2.12}{Version 2.12}
+ \item{Major fixes to the \code{macho} backend (\nref{machofmt}); earlier versions
+ would produce invalid symbols and relocations on a regular basis.}
+ \item{Support for thread-local storage in Mach-O.}
+ \item{Support for arbitrary sections in Mach-O.}
+ \item{Fix wrong negative size treated as a big positive value passed into
+ backend causing NASM to crash.}
+ \item{Fix handling of zero-extending unsigned relocations, we have been printing
+ wrong message and forgot to assign segment with predefined value before
+ passing it into output format.}
+ \item{Fix potential write of oversized (with size greater than allowed in
+ output format) relative relocations.}
+ \item{Portability fixes for building NASM with the LLVM compiler.}
+ \item{Add support of Codeview version 8 (\code{cv8}) debug format for
+ \code{win32} and \code{win64} formats in the \code{COFF} backend,
+ see \nref{codeview}.}
+ \item{Allow 64-bit outputs in 16/32-bit only backends. Unsigned 64-bit
+ relocations are zero-extended from 32-bits with a warning
+ (suppressible via \code{-w-zext-reloc}); signed 64-bit relocations are
+ an error.}
+ \item{Line numbers in list files now correspond to the lines in the source
+ files, instead of simply being sequential.}
+ \item{There is now an official 64-bit (x64 a.k.a. x86-64) build for Windows.}
+\xsubsection{cl-2.11.09}{Version 2.11.09}
+ \item{Fix potential stack overwrite in \code{macho32} backend.}

+ \item{Adjust \code{.symtab} and \code{.rela.text} sections alignments to 8 bytes
+ in \code{elf64} backed.}
+ \item{Fix section length computation in \code{bin} backend which leaded in incorrect
+ relocation records.}
+\xsubsection{cl-2.11.08}{Version 2.11.08}
+ \item{Fix section length computation in \code{bin} backend which leaded in incorrect
+ relocation records.}
+ \item{Add a warning for numeric preprocessor definitions passed via command
+ line which might have unexpected results otherwise.}
+ \item{Add ability to specify a module name record in \code{rdoff} linker with
+ \code{-mn} option.}
+ \item{Increase label length capacity up to 256 bytes in \code{rdoff} backend for
+ FreePascal sake, which tends to generate very long labels for procedures.}
+ \item{Fix segmentation failure when rip addressing is used in \code{macho64} backend.}
+ \item{Fix access on out of memory when handling strings with a single
+ grave. We have sixed similar problem in previous release but not
+ all cases were covered.}
+ \item{Fix NULL dereference in disassembled on \code{BND} instruction.}
+\xsubsection{cl-2.11.07}{Version 2.11.07}
+ \item{Fix 256 bit \code{VMOVNTPS} instruction.}
+ \item{Fix \code{-MD} option handling, which was rather broken in previous
+ release changing command line api.}
+ \item{Fix access to unitialized space when handling strings with
+ a single grave.}
+ \item{Fix nil dereference in handling memory reference parsing.}
+\xsubsection{cl-2.11.06}{Version 2.11.06}
+ \item{Update AVX512 instructions based on the Extension Reference (319433-021 Sept 2014).}

+ \item{Updated Win32 Makefile to fix issue with build}
+\xsubsection{cl-2.11.05}{Version 2.11.05}
+ \item{Add \code{--v} as an alias for \code{-v} (see \nref{opt-v}), for
+ command-line compatibility with Yasm.}
+ \item{Fix a bug introduced in 2.11.03 whereby certain instructions would
+ contain multiple REX prefixes, and thus be corrupt.}
+\xsubsection{cl-2.11.04}{Version 2.11.04}
+ \item{Removed an invalid error checking code. Sometimes a memref only with
+ a displacement can also set an evex flag. For example:
+vmovdqu32 [0xabcd]{k1}, zmm0
+ \item{Fixed a bug in disassembler that EVEX.L'L vector length was not matched
+ when EVEX.b was set because it was simply considered as EVEC.RC.
+ Separated EVEX.L'L case from EVEX.RC which is ignored in matching.}
+\xsubsection{cl-2.11.03}{Version 2.11.03}
+ \item{Fix a bug there REX prefixes were missing on instructions
+ inside a \code{TIMES} statement.}
+\xsubsection{cl-2.11.02}{Version 2.11.02}

+\xsubsection{cl-2.11.01}{Version 2.11.01}
+ \item{Allow instructions which implicitly uses \code{XMM0} (\code{VBLENDVPD},
+ \code{VBLENDVPS}, \code{PBLENDVB} and \code{SHA256RNDS2}) to be specified
+ without an explicit \code{xmm0} on the assembly line. In other words,
+ the following two lines produce the same output:
+vblendvpd xmm2,xmm1,xmm0 ; Last operand is fixed xmm0
+vblendvpd xmm2,xmm1 ; Implicit xmm0 omitted
+ \item{In the ELF backends, don't crash the assembler if \code{section align}
+ is specified without a value.}
+\xsubsection{cl-2.11}{Version 2.11}
+ \item{Add support for the Intel AVX-512 instruction set:}
+ \item{16 new, 512-bit SIMD registers. Total 32 \code{(ZMM0 \textasciitilde ZMM31)}}
+ \item{8 new opmask registers \code{(K0 \textasciitilde K7)}.
+ One of 7 registers \code{(K1 \textasciitilde K7)} can
+ be used as an opmask for conditional execution.}
+ \item{A new EVEX encoding prefix. EVEX is based on VEX and provides more
+ capabilities: opmasks, broadcasting, embedded rounding and compressed
+ displacements.
+; opmask: conditional vector operation
+; using opmask k1 and {z} is for zero-masking
+ VDIVPD zmm0{k1}{z}, zmm1, zmm3
+; broadcasting: load single-precision float and
+; replicate it 16 times. 32 * 16 = 512
+ VDIVPS zmm4, zmm5, [rbx]{1to16}
+; embedded rounding: round toward zero. note that
+: it is used as if a separate operand. it comes after
+; the last SIMD operand
+ VCVTSI2SD xmm6, xmm7, {rz-sae}, rax
+ \item{Add support for \code{ZWORD} (512 bits), \code{DZ} and \code{RESZ}.}

+ \item{Better handling of section redefinition.}
+ \item{Generate manpages when running \code{'make dist'}.}
+ \item{Handle all token chains in mmacro params range.}
+ \item{Support split [base,index] effective address:
+; eax=base, ecx=index, 4=scale, 8=disp
+mov eax,[eax+8,ecx*4]
+ This is expected to be most useful for the MPX instructions.}
+ \item{Support \code{BND} prefix for branch instructions (for MPX).}
+ \item{The \code{DEFAULT} directive can now take \code{BND} and \code{NOBND}
+ options to indicate whether all relevant branches should be getting
+ \code{BND} prefixes. This is expected to be the normal for use in MPX
+ code.}
+ \item{Add \code{{evex}}, \code{{vex3}} and \code{{vex2}} instruction prefixes to
+ have NASM encode the corresponding instruction, if possible, with an EVEX,
+ 3-byte VEX, or 2-byte VEX prefix, respectively.}
+ \item{Support for section names longer than 8 bytes in Win32/Win64 COFF.}
+ \item{The \code{NOSPLIT} directive by itself no longer forces a single
+ register to become an index register, unless it has an explicit
+ multiplier.
+mov eax,[nosplit eax] ; eax as base register
+mov eax,[nosplit eax*1] ; eax as index register
+\xsubsection{cl-2.10.09}{Version 2.10.09}
+ \item{Pregenerate man pages.}

+ dependency generation options.}
+ \item{If no dependency target name is specified via the \code{-MT} or
+ \code{-MQ} options, quote the default output name.}

+\xsubsection{cl-2.10.03}{Version 2.10.03}
+ \item{Correct the assembly of the instruction:
+XRELEASE MOV [absolute],AL
+ Previous versions would incorrectly generate \code{F3 A2} for this
+ instruction and issue a warning; correct behavior is to emit \code{F3 88 05}.}
+\xsubsection{cl-2.10.02}{Version 2.10.02}
+ \item{Add the \code{ifunc} macro package with integer functions, currently
+ only integer logarithms. See \nref{pkgifunc}.}

+ shortest form possible between:
+mov r32,imm32 ; 5 bytes
+mov r64,imm32 ; 7 bytes
+mov r64,imm64 ; 10 bytes
+ To force a specific form, use the \code{STRICT} keyword, see \nref{strict}.}
+ \item{Add support for the Intel AVX2 instruction set.}
+ \item{Add support for Bit Manipulation Instructions 1 and 2.}
+ \item{Add support for Intel Transactional Synchronization Extensions (TSX).}
+ \item{Add support for x32 ELF (32-bit ELF with the CPU in 64-bit mode.) See \nref{elffmt}.}
+ \item{Add support for bigendian UTF-16 and UTF-32. See \nref{unicode}.}
+\xsubsection{cl-2.09.10}{Version 2.09.10}
+ \item{Fix up NSIS script to protect uninstaller against registry keys
+ absence or corruption. It brings in a few additional questions
+ to a user during deinstallation procedure but still it is better
+ than unpredictable file removal.}
+\xsubsection{cl-2.09.09}{Version 2.09.09}
+ \item{Fix initialization of section attributes of \code{bin} output format.}
+ \item{Fix \code{mach64} output format bug that crashes NASM due to NULL symbols.}
+\xsubsection{cl-2.09.08}{Version 2.09.08}
+ \item{Fix \code{\_\_OUTPUT\_FORMAT\_\_} assignment when output driver alias
+ is used. For example when \code{-f elf} is used \code{\_\_OUTPUT\_FORMAT\_\_}
+ must be set to \code{elf}, if \code{-f elf32} is used \code{\_\_OUTPUT\_FORMAT\_\_}
+ must be assigned accordingly, i.e. to \code{elf32}. The rule applies to
+ all output driver aliases. See \nref{ofmtm}.}

+ \item{Fix arguments encoding for VPEXTRW instruction.}
+ \item{Remove invalid form of VPEXTRW instruction.}
+ \item{Add \code{VLDDQU} as alias for \code{VLDQQU} to match specification.}
+\xsubsection{cl-2.09.04}{Version 2.09.04}
+ \item{Fix incorrect labels offset for VEX intructions.}

+Changes from 0.98.07 release to 98.09b as of 28-Oct-2001
+ \item{More closely compatible with 0.98 when \code{-O0} is implied
+ or specified. Not strictly identical, since backward
+ branches in range of short offsets are recognized, and signed
+ byte values with no explicit size specification will be
+ assembled as a single byte.}
+ \item{More forgiving with the PUSH instruction. 0.98 requires
+ a size to be specified always. 0.98.09b will imply the size
+ from the current BITS setting (16 or 32).}
+ \item{Changed definition of the optimization flag
+ \begin{itemize}
+ \item{\code{-O0}: strict two-pass assembly, JMP and Jcc are
+ handled more like 0.98, except that back ward JMPs are
+ short, if possible.}
+ \item{\code{-O1}: strict two-pass assembly, but forward
+ branches are assembled with code guaranteed
+ to reach; may produce larger code than
+ \code{-O0}, but will produce successful assembly
+ more often if branch offset sizes are not
+ specified.}
+ \item{\code{-O2}: multi-pass optimization, minimize branch
+ offsets; also will minimize signed immediate bytes,
+ overriding size specification.}
+ \item{\code{-O3}: like \code{-O2}, but more passes taken,
+ if needed}

+\xsubsection{cl-0.98.03}{Version 0.98.03 with John Coffman's changes released 27-Jul-2000}
+ \item{Added signed byte optimizations for the 0x81/0x83 class
+ of instructions: ADC, ADD, AND, CMP, OR, SBB, SUB, XOR:
+ when used as 'ADD reg16,imm' or 'ADD reg32,imm.' Also
+ optimization of signed byte form of 'PUSH imm' and 'IMUL
+ reg,imm'/'IMUL reg,reg,imm.' No size specification is needed.}
+ \item{Added multi-pass JMP and Jcc offset optimization. Offsets
+ on forward references will preferentially use the short form,
+ without the need to code a specific size (short or near) for
+ the branch. Added instructions for 'Jcc label' to use the
+ form 'Jnotcc \$+3/JMP label', in cases where a short offset
+ is out of bounds. If compiling for a 386 or higher CPU, then
+ the 386 form of Jcc will be used instead.
+ This feature is controlled by a new command-line switch: "O",
+ (upper case letter O). "-O0" reverts the assembler to no
+ extra optimization passes, "-O1" allows up to 5 extra passes,
+ and "-O2"(default), allows up to 10 extra optimization passes.}
+ \item{Added a new directive: 'cpu XXX', where XXX is any of:
+ 8086, 186, 286, 386, 486, 586, pentium, 686, PPro, P2, P3 or
+ Katmai. All are case insensitive. All instructions will
+ be selected only if they apply to the selected cpu or lower.
+ Corrected a couple of bugs in cpu-dependence in 'insns.dat'.}
+ \item{Added to 'standard.mac', the "use16" and "use32" forms of
+ the "bits 16/32" directive. This is nothing new, just conforms
+ to a lot of other assemblers. (minor)}
+ \item{Changed label allocation from 320/32 (10000 labels @ 200K+)
+ to 32/37 (1000 labels); makes running under DOS much easier.
+ Since additional label space is allocated dynamically, this
+ should have no effect on large programs with lots of labels.
+ The 37 is a prime, believed to be better for hashing. (minor)}
+\xsubsection{cl-0.98.03}{Version 0.98.03}
+"Integrated patchfile 0.98-0.98.01. I call this version 0.98.03 for
+historical reasons: 0.98.02 was trashed." --John Coffman
+<johninsd@san.rr.com>, 27-Jul-2000
+ \item{Kendall Bennett's SciTech MGL changes}
+ \item{Note that you must define "TASM\_COMPAT" at compile-time
+ to get the Tasm Ideal Mode compatibility.}
+ \item{All changes can be compiled in and out using the TASM\_COMPAT macros,
+ and when compiled without TASM\_COMPAT defined we get the exact same
+ binary as the unmodified 0.98 sources.}
+ \item{standard.mac, macros.c: Added macros to ignore TASM directives before
+ first include}
+ \item{nasm.h: Added extern declaration for tasm\_compatible\_mode}
+ \item{nasm.c: Added global variable tasm\_compatible\_mode}
+ \item{Added command line switch for TASM compatible mode (-t)}
+ \item{Changed version command line to reflect when compiled with TASM additions}
+ \item{Added response file processing to allow all arguments on a single
+ line (response file is @resp rather than -@resp for NASM format).}
+ \item{labels.c: Changes islocal() macro to support TASM style @@local labels.}
+ \item{Added islocalchar() macro to support TASM style @@local labels.}
+ \item{parser.c: Added support for TASM style memory references (ie: mov
+ [DWORD eax],10 rather than the NASM style mov DWORD [eax],10).}
+ \item{preproc.c: Added new directives, \code{\%arg}, \code{\%local},
+ \code{\%stacksize} to directives table}
+ \item{Added support for TASM style directives without a leading \% symbol.}
+ \item{Integrated a block of changes from Andrew Zabolotny <bit@eltech.ru>:}
+ \item{A new keyword \code{\%xdefine} and its case-insensitive counterpart
+ \code{\%ixdefine}. They work almost the same way as \code{\%define} and
+ \code{\%idefine} but expand the definition immediately, not on the invocation.
+ Something like a cross between \code{\%define} and \code{\%assign}. The "x"
+ suffix stands for "eXpand", so "xdefine" can be deciphered as "expand-and-define".
+ Thus you can do things like this:
+%assign ofs 0
+%macro arg 1
+ %xdefine %1 dword [esp+ofs]
+ %assign ofs ofs+4
+ \item{Changed the place where the expansion of \%\$name macros are expanded.
+ Now they are converted into ..@ctxnum.name form when detokenizing, so
+ there are no quirks as before when using \%\$name arguments to macros,
+ in macros etc. For example:
+%macro abc 1
+ %define %1 hello
+ abc %$here
+ Now last line will be expanded into "hello" as expected. This also allows
+ for lots of goodies, a good example are extended "proc" macros included
+ in this archive.}
+ \item{Added a check for "cstk" in smacro\_defined() before calling get\_ctx() -
+ this allows for things like:
+%ifdef %$abc
+ work without warnings even in no context.}
+ \item{Added a check for "cstk" in \%if*ctx and \%elif*ctx directives -
+ this allows to use \code{\%ifctx} without excessive warnings. If there is
+ no active context, \code{\%ifctx} goes through "false" branch.}
+ \item{Removed "user error: " prefix with \code{\%error} directive: it just clobbers the
+ output and has absolutely no functionality. Besides, this allows to write
+ macros that does not differ from built-in functions in any way.}
+ \item{Added expansion of string that is output by \code{\%error} directive. Now you
+ can do things like:
+%define hello(x) Hello, x!
+%define %$name andy
+%error "hello(%$name)"
+ Same happened with \code{\%include} directive.}
+ \item{Now all directives that expect an identifier will try to expand and
+ concatenate everything without whitespaces in between before usage.
+ For example, with "unfixed" nasm the commands
+%define %$abc hello
+%define __%$abc goodbye
+ would produce "incorrect" output: last line will expand to
+hello goodbyehello
+ Not quite what you expected, eh? :-) The answer is that preprocessor
+ treats the \code{\%define} construct as if it would be
+%define __ %$abc goodbye
+ (note the white space between \_\_ and \%\$abc). After my "fix" it
+ will "correctly" expand into
+ as expected. Note that I use quotes around words "correct", "incorrect"
+ etc because this is rather a feature not a bug; however current behaviour
+ is more logical (and allows more advanced macro usage :-).
+ Same change was applied to: \code{\%push},\code{\%macro},\code{\%imacro},
+ \code{\%define},\code{\%idefine},\code{\%xdefine},\code{\%ixdefine},
+ \code{\%assign},\code{\%iassign},\code{\%undef}}
+ \item{A new directive \code{[WARNING {+|-}warning-id]} have been added. It works only
+ if the assembly phase is enabled (i.e. it doesn't work with nasm -e).}
+ \item{A new warning type: macro-selfref. By default this warning is disabled;
+ when enabled NASM warns when a macro self-references itself; for example
+ the following source:
+[WARNING macro-selfref]
+%macro push 1-*
+ %rep %0
+ push %1
+ %rotate 1
+ %endrep
+ push eax,ebx,ecx
+ will produce a warning, but if we remove the first line we won't see it
+ anymore (which is The Right Thing To Do \texttrademark IMHO since C
+ preprocessor eats such constructs without warnings at all).}
+ \item{Added a "error" routine to preprocessor which always will set ERR\_PASS1
+ bit in severity\_code. This removes annoying repeated errors on first
+ and second passes from preprocessor.}
+ \item{Added the \%+ operator in single-line macros for concatenating two
+ identifiers. Usage example:
+%define _myfunc _otherfunc
+%define cextern(x) _ %+ x
+cextern (myfunc)
+ After first expansion, third line will become "\_myfunc". After this
+ expansion is performed again so it becomes "\_otherunc".}
+ \item{Now if preprocessor is in a non-emitting state, no warning or error
+ will be emitted. Example:
+%if 1
+ mov eax,ebx
+ put anything you want between these two brackets,
+ even macro-parameter references %1 or local
+ labels %$zz or macro-local labels %%zz - no
+ warning will be emitted.
+ \item{Context-local variables on expansion as a last resort are looked up
+ in outer contexts. For example, the following piece:
+%push outer
+%define %$a [esp]
+ %push inner
+ %$a
+ %pop
+ will expand correctly the fourth line to [esp]; if we'll define another
+ \%\$a inside the "inner" context, it will take precedence over outer
+ definition. However, this modification has been applied only to
+ expand\_smacro and not to smacro\_define: as a consequence expansion
+ looks in outer contexts, but \code{\%ifdef} won't look in outer contexts.
+ This behaviour is needed because we don't want nested contexts to
+ act on already defined local macros. Example:
+%define %$arg1 [esp+4]
+test eax,eax
+if nz
+ mov eax,%$arg1
+ In this example the "if" mmacro enters into the "if" context, so \%\$arg1
+ is not valid anymore inside "if". Of course it could be worked around
+ by using explicitely \%\$\$arg1 but this is ugly IMHO.}
+ \item{Fixed memory leak in \code{\%undef}. The origline wasn't freed before exiting on success.}
+ \item{Fixed trap in preprocessor when line expanded to empty set of tokens.
+ This happens, for example, in the following case:
+#define SOMETHING
+\xsubsection{cl-0.98}{Version 0.98}
+All changes since NASM 0.98p3 have been produced by H. Peter Anvin <hpa@zytor.com>.
+ \item{The documentation comment delimiter is \code{\textbackslash \#} not \code{\#}.}
+ \item{Allow EQU definitions to refer to external labels; reported by Pedro Gimeno.}

+ \item{Updated License file per OK from Simon and Julian.}
+\xsubsection{cl-0.98p9}{Version 0.98p9}
+ \item{Update documentation (although the instruction set reference will
+ have to wait; I don't want to hold up the 0.98 release for it.)}
+ \item{Verified that the NASM implementation of the PEXTRW and PMOVMSKB
+ instructions is correct. The encoding differs from what the Intel
+ manuals document, but the Pentium III behaviour matches NASM, not
+ the Intel manuals.}
+ \item{Fix handling of implicit sizes in PSHUFW and PINSRW, reported by
+ Stefan Hoffmeister.}
+ \item{Resurrect the -s option, which was removed when changing the
+ diagnostic output to stdout.}
+\xsubsection{cl-0.98p8}{Version 0.98p8}
+ \item{Fix for "DB" when NASM is running on a bigendian machine.}
+ \item{Invoke insns.pl once for each output script, making Makefile.in
+ legal for "make -j".}
+ \item{Improve the Unix configure-based makefiles to make package
+ creation easier.}
+ \item{Included an RPM .spec file for building RPM (RedHat Package Manager)
+ packages on Linux or Unix systems.}
+ \item{Fix Makefile dependency problems.}
+ \item{Change src/rdsrc.pl to include sectioning information in info
+ output; required for install-info to work.}
+ \item{Updated the RDOFF distribution to version 2 from Jules; minor
+ massaging to make it compile in my environment.}
+ \item{Split doc files that can be built by anyone with a Perl interpreter off
+ into a separate archive.}
+ \item{"Dress rehearsal" release!}
+\xsubsection{cl-0.98p7}{Version 0.98p7}
+ \item{Fixed opcodes with a third byte-sized immediate argument to not
+ complain if given "byte" on the immediate.}
+ \item{Allow \code{\%undef} to remove single-line macros with arguments. This
+ matches the behaviour of \#undef in the C preprocessor.}
+ \item{Allow -d, -u, -i and -p to be specified as -D, -U, -I and -P for
+ compatibility with most C compilers and preprocessors. This allows
+ Makefile options to be shared between cc and nasm, for example.}
+ \item{Minor cleanups.}
+ \item{Went through the list of Katmai instructions and hopefully fixed the
+ (rather few) mistakes in it.}
+ \item{(Hopefully) fixed a number of disassembler bugs related to ambiguous
+ instructions (disambiguated by -p) and SSE instructions with REP.}
+ \item{Fix for bug reported by Mark Junger: "call dword 0x12345678" should
+ work and may add an OSP (affected CALL, JMP, Jcc).}
+ \item{Fix for environments when "stderr" isn't a compile-time constant.}
+\xsubsection{cl-0.98p6}{Version 0.98p6}
+ \item{Took officially over coordination of the 0.98 release; so drop
+ the p3.x notation. Skipped p4 and p5 to avoid confusion with John
+ Fine's J4 and J5 releases.}
+ \item{Update the documentation; however, it still doesn't include
+ documentation for the various new instructions. I somehow wonder if
+ it makes sense to have an instruction set reference in the assembler
+ manual when Intel et al have PDF versions of their manuals online.}
+ \item{Recognize "idt" or "centaur" for the -p option to ndisasm.}
+ \item{Changed error messages back to stderr where they belong, but add an
+ -E option to redirect them elsewhere (the DOS shell cannot redirect
+ stderr.)}
+ \item{-M option to generate Makefile dependencies (based on code from Alex Verstak.)}
+ \item{\code{\%undef} preprocessor directive, and -u option, that undefines a
+ single-line macro.}
+ \item{OS/2 Makefile (Mkfiles/Makefile.os2) for Borland under OS/2; from
+ Chuck Crayne.}
+ \item{Various minor bugfixes (reported by):
+ - Dangling \code{\%s} in preproc.c (Martin Junker)}
+ on a trip and didn't bring the Katmai instruction reference, so I
+ can't work on them right now.}
+ \item{Updated the License file per agreement with Simon and Jules to
+ include a GPL distribution clause.}
+\xsubsection{cl-0.98p3.7}{Version 0.98p3.7}

+ \item{Renamed changes.asm to changed.asm.}
+\xsubsection{cl-0.98p3.6}{Version 0.98p3.6}
+ \item{Fixed a bunch of instructions that were added in 0.98p3.5 which had
+ memory operands, and the address-size prefix was missing from the
+ instruction pattern.}
+\xsubsection{cl-0.98p3.5}{Version 0.98p3.5}
+ \item{Merged in changes from John S. Fine's 0.98-J5 release. John's based
+ 0.98-J5 on my 0.98p3.3 release; this merges the changes.}
+ \item{Expanded the instructions flag field to a long so we can fit more
+ flags; mark SSE (KNI) and AMD or Katmai-specific instructions as
+ such.}
+ \item{Fix the "PRIV" flag on a bunch of instructions, and create new
+ "PROT" flag for protected-mode-only instructions (orthogonal to if
+ the instruction is privileged!) and new "SMM" flag for SMM-only
+ instructions.}
+ \item{Added AMD-only SYSCALL and SYSRET instructions.}
+ \item{Make SSE actually work, and add new Katmai MMX instructions.}
+ \item{Added a -p (preferred vendor) option to ndisasm so that it can
+ distinguish e.g. Cyrix opcodes also used in SSE. For example:
+ndisasm -p cyrix aliased.bin
+00000000 670F514310 paddsiw mm0,[ebx+0x10]
+00000005 670F514320 paddsiw mm0,[ebx+0x20]

+00000005 670F514320 sqrtps xmm0,[ebx+0x20]
+ \item{Added a bunch of Cyrix-specific instructions.}
+\xsubsection{cl-0.98p3.4}{Version 0.98p3.4}
+ \item{Made at least an attempt to modify all the additional Makefiles (in

+ \item{DOS DJGPP+"Opus Make" Makefile from John S. Fine.}
+ \item{changes.asm changes from John S. Fine.}
+\xsubsection{cl-0.98p3.3}{Version 0.98p3.3}
+ \item{Patch from Conan Brink to allow nesting of \code{\%rep} directives.}
+ \item{If we're going to allow INT01 as an alias for INT1/ICEBP (one of
+ Jules 0.98p3 changes), then we should allow INT03 as an alias for INT3
+ as well.}
+ \item{Updated changes.asm to include the latest changes.}
+ \item{Tried to clean up the <CR>s that had snuck in from a DOS/Windows
+ environment into my Unix environment, and try to make sure than
+ DOS/Windows users get them back.}
+ \item{We would silently generate broken tools if insns.dat wasn't sorted
+ properly. Change insns.pl so that the order doesn't matter.}
+ \item{Fix bug in insns.pl (introduced by me) which would cause conditional
+ instructions to have an extra "cc" in disassembly, e.g. "jnz"
+ disassembled as "jccnz".}
+\xsubsection{cl-0.98p3.2}{Version 0.98p3.2}
+ \item{Merged in John S. Fine's changes from his 0.98-J4 prerelease; see
+ http://www.csoft.net/cz/johnfine/}
+ \item{Changed previous "spotless" Makefile target (appropriate for distribution)
+ to "distclean", and added "cleaner" target which is same as "clean"
+ except deletes files generated by Perl scripts; "spotless" is union.}
+ \item{Removed BASIC programs from distribution. Get a Perl interpreter
+ instead (see below.)}
+ \item{Calling this "pre-release 3.2" rather than "p3-hpa2" because of
+ John's contributions.}
+ \item{Actually link in the IEEE output format (zoutieee.c); fix a bunch of
+ compiler warnings in that file. Note I don't know what IEEE output
+ is supposed to look like, so these changes were made "blind".}
+\xsubsection{cl-0.98p3-hpa}{Version 0.98p3-hpa}
+ \item{Merged nasm098p3.zip with nasm-0.97.tar.gz to create a fully
+ buildable version for Unix systems (Makefile.in updates, etc.)}
+ \item{Changed insns.pl to create the instruction tables in nasm.h and
+ names.c, so that a new instruction can be added by adding it *only*
+ to insns.dat.}
+ \item{Added the following new instructions: SYSENTER, SYSEXIT, FXSAVE,
+ FXRSTOR, UD1, UD2 (the latter two are two opcodes that Intel
+ guarantee will never be used; one of them is documented as UD2 in
+ Intel documentation, the other one just as "Undefined Opcode" --
+ calling it UD1 seemed to make sense.)}
+ \item{MAX\_SYMBOL was defined to be 9, but LOADALL286 and LOADALL386 are 10
+ characters long. Now MAX\_SYMBOL is derived from insns.dat.}
+ \item{A note on the BASIC programs included: forget them. insns.bas is
+ already out of date. Get yourself a Perl interpreter for your
+ platform of choice at \href{http://www.cpan.org/ports/index.html}
+ {http://www.cpan.org/ports/index.html}.}
+\xsubsection{cl-0.98p3}{Version 0.98 pre-release 3}
+ \item{added response file support, improved command line handling,

+ \item{Fixed a bug whereby STRUC didn't work at all in RDF.}
+ \item{Fixed a problem with group specification in PUBDEFs in OBJ.}
+ \item{Improved ease of adding new output formats. Contribution due to Fox Cutter.}
+ \item{Fixed a bug in relocations in the `bin' format: was showing up when
+ a relocatable reference crossed an 8192-byte boundary in any output
+ section.}
+ \item{Fixed a bug in local labels: local-label lookups were inconsistent
+ between passes one and two if an EQU occurred between the definition
+ of a global label and the subsequent use of a local label local to
+ that global.}
+ \item{Fixed a seg-fault in the preprocessor (again) which happened when
+ you use a blank line as the first line of a multi-line macro
+ definition and then defined a label on the same line as a call to
+ that macro.}
+ \item{Fixed a stale-pointer bug in the handling of the NASM environment
+ variable. Thanks to Thomas McWilliams.}
+ \item{ELF had a hard limit on the number of sections which caused
+ segfaults when transgressed. Fixed.}
+ \item{Added ability for ndisasm to read from stdin by using `-' as the
+ filename.}
+ \item{ndisasm wasn't outputting the TO keyword. Fixed.}
+ \item{Fixed error cascade on bogus expression in \code{\%if} - an error in
+ evaluation was causing the entire \code{\%if} to be discarded, thus creating
+ trouble later when the \code{\%else} or \code{\%endif} was encountered.}
+ \item{Forward reference tracking was instruction-granular not operand-
+ granular, which was causing 286-specific code to be generated
+ needlessly on code of the form `shr word [forwardref],1'. Thanks to
+ Jim Hague for sending a patch.}
+ \item{All messages now appear on stdout, as sending them to stderr serves
+ no useful purpose other than to make redirection difficult.}
+ \item{Fixed the problem with EQUs pointing to an external symbol - this
+ now generates an error message.}
+ \item{Allowed multiple size prefixes to an operand, of which only the first
+ is taken into account.}

+ than after.}
+ \item{Reformatted a lot of the source code to be more readable. Included
+ 'coding.txt' as a guideline for how to format code for contributors.}

+ specification warning when sizes agree).}
+\xsection{cl-0.9x}{NASM 0.9 Series}
+Revisions before 0.98.
+\xsubsection{cl-0.97}{Version 0.97 released December 1997}
+ \item{This was entirely a bug-fix release to 0.96, which seems to have got
+ cursed. Silly me.}
+ \item{Fixed stupid mistake in OBJ which caused `MOV EAX,<constant>' to
+ fail. Caused by an error in the `MOV EAX,<segment>' support.}
+ \item{ndisasm hung at EOF when compiled with lcc on Linux because lcc on
+ Linux somehow breaks feof(). ndisasm now does not rely on feof().}
+ \item{A heading in the documentation was missing due to a markup error in
+ the indexing. Fixed.}
+ \item{Fixed failure to update all pointers on realloc() within extended-
+ operand code in parser.c. Was causing wrong behaviour and seg faults
+ on lines such as `dd 0.0,0.0,0.0,0.0,...'}
+ \item{Fixed a subtle preprocessor bug whereby invoking one multi-line
+ macro on the first line of the expansion of another, when the second
+ had been invoked with a label defined before it, didn't expand the
+ inner macro.}
+ \item{Added internal.doc back in to the distribution archives - it was
+ missing in 0.96 *blush*}
+ \item{Fixed bug causing 0.96 to be unable to assemble its own test files,
+ specifically objtest.asm. *blush again*}
+ \item{Fixed seg-faults and bogus error messages caused by mismatching
+ \code{\%rep} and \code{\%endrep} within multi-line macro definitions.}
+ \item{Fixed a problem with buffer overrun in OBJ, which was causing
+ corruption at ends of long PUBDEF records.}
+ \item{Separated DOS archives into main-program and documentation to reduce
+ download size.}
+\xsubsection{cl-0.96}{Version 0.96 released November 1997}
+ \item{Fixed a bug whereby, if `nasm sourcefile' would cause a filename
+ collision warning and put output into `nasm.out', then `nasm
+ sourcefile -o outputfile' still gave the warning even though the
+ `-o' was honoured.
+ Fixed name pollution under Digital UNIX: one of its header files
+ defined R\_SP, which broke the enum in nasm.h.}
+ \item{Fixed minor instruction table problems: FUCOM and FUCOMP didn't have
+ two-operand forms; NDISASM didn't recognise the longer register
+ forms of PUSH and POP (eg FF F3 for PUSH BX); TEST mem,imm32 was
+ flagged as undocumented; the 32-bit forms of CMOV had 16-bit operand
+ size prefixes; `AAD imm' and `AAM imm' are no longer flagged as
+ undocumented because the Intel Architecture reference documents
+ them.}
+ \item{Fixed a problem with the local-label mechanism, whereby strange
+ types of symbol (EQUs, auto-defined OBJ segment base symbols)
+ interfered with the `previous global label' value and screwed up
+ local labels.}
+ \item{Fixed a bug whereby the stub preprocessor didn't communicate with
+ the listing file generator, so that the -a and -l options in
+ conjunction would produce a useless listing file.}
+ \item{Merged `os2' object file format back into `obj', after discovering
+ that `obj' \emph{also} shouldn't have a link pass separator in a module
+ containing a non-trivial MODEND. Flat segments are now declared
+ using the FLAT attribute. `os2' is no longer a valid object format
+ name: use `obj'.}
+ \item{Removed the fixed-size temporary storage in the evaluator. Very very
+ long expressions (like `mov ax,1+1+1+1+...' for two hundred 1s or
+ so) should now no longer crash NASM.}
+ \item{Fixed a bug involving segfaults on disassembly of MMX instructions,
+ by changing the meaning of one of the operand-type flags in nasm.h.
+ This may cause other apparently unrelated MMX problems; it needs to
+ be tested thoroughly.}
+ \item{Fixed some buffer overrun problems with large OBJ output files.
+ Thanks to DJ Delorie for the bug report and fix.}
+ \item{Made preprocess-only mode actually listen to the \code{\%line} markers as it
+ prints them, so that it can report errors more sanely.}
+ \item{Re-designed the evaluator to keep more sensible track of expressions
+ involving forward references: can now cope with previously-nightmare
+ situations such as:
+mov ax,foo | bar
+foo equ 1
+bar equ 2
+ \item{Added the ALIGN and ALIGNB standard macros.}
+ \item{Added PIC support in ELF: use of WRT to obtain the four extra
+ relocation types needed.}
+ \item{Added the ability for output file formats to define their own
+ extensions to the GLOBAL, COMMON and EXTERN directives.}
+ \item{Implemented common-variable alignment, and global-symbol type and
+ size declarations, in ELF.}
+ \item{Implemented NEAR and FAR keywords for common variables, plus
+ far-common element size specification, in OBJ.}
+ \item{Added a feature whereby EXTERNs and COMMONs in OBJ can be given a
+ default WRT specification (either a segment or a group).}
+ \item{Transformed the Unix NASM archive into an auto-configuring package.}
+ \item{Added a sanity-check for people applying SEG to things which are
+ already segment bases: this previously went unnoticed by the SEG
+ processing and caused OBJ-driver panics later.}
+ \item{Added the ability, in OBJ format, to deal with `MOV EAX,<segment>'
+ type references: OBJ doesn't directly support dword-size segment
+ base fixups, but as long as the low two bytes of the constant term
+ are zero, a word-size fixup can be generated instead and it will
+ work.}
+ \item{Added the ability to specify sections' alignment requirements in
+ Win32 object files and pure binary files.}
+ \item{Added preprocess-time expression evaluation: the \code{\%assign} (and
+ \code{\%iassign}) directive and the bare \code{\%if} (and \code{\%elif}) conditional.
+ Added relational operators to the evaluator, for use only in \code{\%if}
+ constructs: the standard relationals = < > <= >= <> (and C-like
+ synonyms == and !=) plus low-precedence logical operators \&\&,
+ \textasciicircum \textasciicircum and ||.}
+ \item{Added a preprocessor repeat construct: \code{\%rep}, \code{\%exitrep},
+ \code{\%endrep}.}
+ \item{Added the \_\_FILE\_\_ and \_\_LINE\_\_ standard macros.}
+ \item{Added a sanity check for number constants being greater than
+ 0xFFFFFFFF. The warning can be disabled.}
+ \item{Added the \%0 token whereby a variadic multi-line macro can tell how
+ many parameters it's been given in a specific invocation.}
+ \item{Added \code{\%rotate}, allowing multi-line macro parameters to be cycled.}
+ \item{Added the `*' option for the maximum parameter count on multi-line
+ macros, allowing them to take arbitrarily many parameters.}
+ \item{Added the ability for the user-level forms of EXTERN, GLOBAL and
+ COMMON to take more than one argument.}
+ \item{Added the IMPORT and EXPORT directives in OBJ format, to deal with
+ Windows DLLs.}
+ \item{Added some more preprocessor \code{\%if} constructs: \code{\%ifidn},
+ \code{\%ifidni} (exact textual identity), and \code{\%ifid},
+ \code{\%ifnum}, \code{\%ifstr} (token type testing).}
+ \item{Added the ability to distinguish SHL AX,1 (the 8086 version) from
+ SHL AX,BYTE 1 (the 286-and-upwards version whose constant happens to
+ be 1).}
+ \item{Added NetBSD/FreeBSD/OpenBSD's variant of a.out format, complete
+ with PIC shared library features.}
+ \item{Changed NASM's idiosyncratic handling of FCLEX, FDISI, FENI, FINIT,
+ FSAVE, FSTCW, FSTENV, and FSTSW to bring it into line with the
+ otherwise accepted standard. The previous behaviour, though it was a
+ deliberate feature, was a deliberate feature based on a
+ misunderstanding. Apologies for the inconvenience.}
+ \item{Improved the flexibility of ABSOLUTE: you can now give it an
+ expression rather than being restricted to a constant, and it can
+ take relocatable arguments as well.}
+ \item{Added the ability for a variable to be declared as EXTERN multiple
+ times, and the subsequent definitions are just ignored.}
+ \item{We now allow instruction prefixes (CS, DS, LOCK, REPZ etc) to be
+ alone on a line (without a following instruction).}
+ \item{Improved sanity checks on whether the arguments to EXTERN, GLOBAL
+ and COMMON are valid identifiers.}
+ \item{Added misc/exebin.mac to allow direct generation of .EXE files by
+ hacking up an EXE header using DB and DW; also added test/binexe.asm
+ to demonstrate the use of this. Thanks to Yann Guidon for
+ contributing the EXE header code.}
+ \item{ndisasm forgot to check whether the input file had been successfully
+ opened. Now it does. Doh!}
+ \item{Added the Cyrix extensions to the MMX instruction set.}
+ \item{Added a hinting mechanism to allow [EAX+EBX] and [EBX+EAX] to be
+ assembled differently. This is important since [ESI+EBP] and
+ [EBP+ESI] have different default base segment registers.}
+ \item{Added support for the PharLap OMF extension for 4096-byte segment
+ alignment.}
+\xsubsection{cl-0.95}{Version 0.95 released July 1997}
+ \item{Fixed yet another ELF bug. This one manifested if the user relied on
+ the default segment, and attempted to define global symbols without
+ first explicitly declaring the target segment.}
+ \item{Added makefiles (for NASM and the RDF tools) to build Win32 console
+ apps under Symantec C++. Donated by Mark Junker.}
+ \item{Added `macros.bas' and `insns.bas', QBasic versions of the Perl
+ scripts that convert `standard.mac' to `macros.c' and convert
+ `insns.dat' to `insnsa.c' and `insnsd.c'. Also thanks to Mark
+ Junker.}
+ \item{Changed the diassembled forms of the conditional instructions so
+ that JB is now emitted as JC, and other similar changes. Suggested
+ list by Ulrich Doewich.}
+ \item{Added `@' to the list of valid characters to begin an identifier with.}
+ \item{Documentary changes, notably the addition of the `Common Problems'
+ section in nasm.doc.}
+ \item{Fixed a bug relating to 32-bit PC-relative fixups in OBJ.}
+ \item{Fixed a bug in perm\_copy() in labels.c which was causing exceptions
+ in cleanup\_labels() on some systems.}
+ \item{Positivity sanity check in TIMES argument changed from a warning to
+ an error following a further complaint.}
+ \item{Changed the acceptable limits on byte and word operands to allow
+ things like `\textasciitilde 10111001b' to work.}
+ \item{Fixed a major problem in the preprocessor which caused seg-faults if
+ macro definitions contained blank lines or comment-only lines.}
+ \item{Fixed inadequate error checking on the commas separating the
+ arguments to `db', `dw' etc.}
+ \item{Fixed a crippling bug in the handling of macros with operand counts
+ defined with a `+' modifier.}
+ \item{Fixed a bug whereby object file formats which stored the input file
+ name in the output file (such as OBJ and COFF) weren't doing so
+ correctly when the output file name was specified on the command
+ line.}
+ \item{Removed [INC] and [INCLUDE] support for good, since they were
+ obsolete anyway.}
+ \item{Fixed a bug in OBJ which caused all fixups to be output in 16-bit
+ (old-format) FIXUPP records, rather than putting the 32-bit ones in
+ FIXUPP32 (new-format) records.}
+ \item{Added, tentatively, OS/2 object file support (as a minor variant
+ on OBJ).}
+ \item{Updates to Fox Cutter's Borland C makefile, Makefile.bc2.}
+ \item{Removed a spurious second fclose() on the output file.}
+ \item{Added the `-s' command line option to redirect all messages which
+ would go to stderr (errors, help text) to stdout instead.}
+ \item{Added the `-w' command line option to selectively suppress some
+ classes of assembly warning messages.}
+ \item{Added the `-p' pre-include and `-d' pre-define command-line options.}
+ \item{Added an include file search path: the `-i' command line option.}
+ \item{Fixed a silly little preprocessor bug whereby starting a line with a
+ `\%!' environment-variable reference caused an `unknown directive'
+ error.}
+ \item{Added the long-awaited listing file support: the `-l' command line
+ option.}
+ \item{Fixed a problem with OBJ format whereby, in the absence of any
+ explicit segment definition, non-global symbols declared in the
+ implicit default segment generated spurious EXTDEF records in the
+ output.}
+ \item{Added the NASM environment variable.}
+ \item{From this version forward, Win32 console-mode binaries will be
+ included in the DOS distribution in addition to the 16-bit binaries.
+ Added Makefile.vc for this purpose.}
+ \item{Added `return 0;' to test/objlink.c to prevent compiler warnings.}
+ \item{Added the \_\_NASM\_MAJOR\_\_ and \_\_NASM\_MINOR\_\_ standard defines.}
+ \item{Added an alternative memory-reference syntax in which prefixing an
+ operand with `\&' is equivalent to enclosing it in square brackets,
+ at the request of Fox Cutter.}
+ \item{Errors in pass two now cause the program to return a non-zero error
+ code, which they didn't before.}
+ \item{Fixed the single-line macro cycle detection, which didn't work at
+ all on macros with no parameters (caused an infinite loop). Also
+ changed the behaviour of single-line macro cycle detection to work
+ like cpp, so that macros like `extrn' as given in the documentation
+ can be implemented.}
+ \item{Fixed the implementation of WRT, which was too restrictive in that
+ you couldn't do `mov ax,[di+abc wrt dgroup]' because (di+abc) wasn't
+ a relocatable reference.}
+\xsubsection{cl-0.94}{Version 0.94 released April 1997}
+ \item{Major item: added the macro processor.}
+ \item{Added undocumented instructions SMI, IBTS, XBTS and LOADALL286. Also
+ reorganised CMPXCHG instruction into early-486 and Pentium forms.
+ Thanks to Thobias Jones for the information.}
+ \item{Fixed two more stupid bugs in ELF, which were causing `ld' to
+ continue to seg-fault in a lot of non-trivial cases.}
+ \item{Fixed a seg-fault in the label manager.}
+ \item{Stopped FBLD and FBSTP from \emph{requiring} the TWORD keyword, which is
+ the only option for BCD loads/stores in any case.}
+ \item{Ensured FLDCW, FSTCW and FSTSW can cope with the WORD keyword, if
+ anyone bothers to provide it. Previously they complained unless no
+ keyword at all was present.}
+ \item{Some forms of FDIV/FDIVR and FSUB/FSUBR were still inverted: a
+ vestige of a bug that I thought had been fixed in 0.92. This was
+ fixed, hopefully for good this time...}
+ \item{Another minor phase error (insofar as a phase error can \emph{ever} be
+ minor) fixed, this one occurring in code of the form
+rol ax,forward_reference
+forward_reference equ 1
+ \item{The number supplied to TIMES is now sanity-checked for positivity,
+ and also may be greater than 64K (which previously didn't work on
+ 16-bit systems).}
+ \item{Added Watcom C makefiles, and misc/pmw.bat, donated by Dominik Behr.}
+ \item{Added the INCBIN pseudo-opcode.}
+ \item{Due to the advent of the preprocessor, the [INCLUDE] and [INC]
+ directives have become obsolete. They are still supported in this
+ version, with a warning, but won't be in the next.}
+ \item{Fixed a bug in OBJ format, which caused incorrect object records to
+ be output when absolute labels were made global.}
+ \item{Updates to RDOFF subdirectory, and changes to outrdf.c.}
+\xsubsection{cl-0.93}{Version 0.93 released January 1997}
+This release went out in a great hurry after semi-crippling bugs
+were found in 0.92.
+ \item{Really \emph{did} fix the stack overflows this time. *blush*}
+ \item{Had problems with EA instruction sizes changing between passes, when
+ an offset contained a forward reference and so 4 bytes were
+ allocated for the offset in pass one; by pass two the symbol had
+ been defined and happened to be a small absolute value, so only 1
+ byte got allocated, causing instruction size mismatch between passes
+ and hence incorrect address calculations. Fixed.}
+ \item{Stupid bug in the revised ELF section generation fixed (associated
+ string-table section for .symtab was hard-coded as 7, even when this
+ didn't fit with the real section table). Was causing `ld' to
+ seg-fault under Linux.}
+ \item{Included a new Borland C makefile, Makefile.bc2, donated by Fox
+ Cutter <lmb@comtch.iea.com>.}
+\xsubsection{cl-0.92}{Version 0.92 released January 1997}
+ \item{The FDIVP/FDIVRP and FSUBP/FSUBRP pairs had been inverted: this was
+ fixed. This also affected the LCC driver.}
+ \item{Fixed a bug regarding 32-bit effective addresses of the form
+ \code{[other\_register+ESP]}.}
+ \item{Documentary changes, notably documentation of the fact that Borland
+ Win32 compilers use `obj' rather than `win32' object format.}
+ \item{Fixed the COMENT record in OBJ files, which was formatted
+ incorrectly.}
+ \item{Fixed a bug causing segfaults in large RDF files.}
+ \item{OBJ format now strips initial periods from segment and group
+ definitions, in order to avoid complications with the local label
+ syntax.}
+ \item{Fixed a bug in disassembling far calls and jumps in NDISASM.}
+ \item{Added support for user-defined sections in COFF and ELF files.}
+ \item{Compiled the DOS binaries with a sensible amount of stack, to
+ prevent stack overflows on any arithmetic expression containing
+ parentheses.}
+ \item{Fixed a bug in handling of files that do not terminate in a newline.}
+\xsubsection{cl-0.91}{Version 0.91 released November 1996}
+ \item{Loads of bug fixes.}
+ \item{Support for RDF added.}
+ \item{Support for DBG debugging format added.}
+ \item{Support for 32-bit extensions to Microsoft OBJ format added.}
+ \item{Revised for Borland C: some variable names changed, makefile added.}
+ \item{LCC support revised to actually work.}
+ \item{JMP/CALL NEAR/FAR notation added.}
+ \item{`a16', `o16', `a32' and `o32' prefixes added.}
+ \item{Range checking on short jumps implemented.}
+ \item{MMX instruction support added.}
+ \item{Negative floating point constant support added.}
+ \item{Memory handling improved to bypass 64K barrier under DOS.}
+ \item{\code{\$} prefix to force treatment of reserved words as identifiers added.}
+ \item{Default-size mechanism for object formats added.}
+ \item{Compile-time configurability added.}
+ \item{\code{\#}, \code{\@}, \code{\textasciitilde} and \code{?} are now valid characters in labels.}
+ \item{\code{-e} and \code{-k} options in NDISASM added.}
+\xsubsection{cl-0.90} Version 0.90 released October 1996
+First release version. First support for object file output. Other
+changes from previous version (0.3x) too numerous to document.
