8 This file details changes since NASM 0.98p3. All the releases in this
9 file have been produced by H. Peter Anvin <hpa@zytor.com>.
12 * The documentation comment delimiter is \# not #.
13 * Allow EQU definitions to refer to external labels; reported by
15 * Re-enable support for RDOFF v1; reported by Pedro Gimeno.
16 * Updated License file per OK from Simon and Julian.
19 * Update documentation (although the instruction set reference will
20 have to wait; I don't want to hold up the 0.98 release for it.)
21 * Verified that the NASM implementation of the PEXTRW and PMOVMSKB
22 instructions is correct. The encoding differs from what the Intel
23 manuals document, but the Pentium III behaviour matches NASM, not
25 * Fix handling of implicit sizes in PSHUFW and PINSRW, reported by
27 * Resurrect the -s option, which was removed when changing the
28 diagnostic output to stdout.
31 * Fix for "DB" when NASM is running on a bigendian machine.
32 * Invoke insns.pl once for each output script, making Makefile.in
34 * Improve the Unix configure-based makefiles to make package
36 * Included an RPM .spec file for building RPM (RedHat Package Manager)
37 packages on Linux or Unix systems.
38 * Fix Makefile dependency problems.
39 * Change src/rdsrc.pl to include sectioning information in info
40 output; required for install-info to work.
41 * Updated the RDOFF distribution to version 2 from Jules; minor
42 massaging to make it compile in my environment.
43 * Split doc files that can be built by anyone with a Perl interpreter off
44 into a separate archive.
45 * "Dress rehearsal" release!
49 * Fixed opcodes with a third byte-sized immediate argument to not
50 complain if given "byte" on the immediate.
51 * Allow %undef to remove single-line macros with arguments. This
52 matches the behaviour of #undef in the C preprocessor.
53 * Allow -d, -u, -i and -p to be specified as -D, -U, -I and -P for
54 compatibility with most C compilers and preprocessors. This allows
55 Makefile options to be shared between cc and nasm, for example.
57 * Went through the list of Katmai instructions and hopefully fixed the
58 (rather few) mistakes in it.
59 * (Hopefully) fixed a number of disassembler bugs related to ambiguous
60 instructions (disambiguated by -p) and SSE instructions with REP.
61 * Fix for bug reported by Mark Junger: "call dword 0x12345678" should
62 work and may add an OSP (affected CALL, JMP, Jcc).
63 * Fix for environments when "stderr" isn't a compile-time constant.
67 * Took officially over coordination of the 0.98 release; so drop
68 the p3.x notation. Skipped p4 and p5 to avoid confusion with John
69 Fine's J4 and J5 releases.
70 * Update the documentation; however, it still doesn't include
71 documentation for the various new instructions. I somehow wonder if
72 it makes sense to have an instruction set reference in the assembler
73 manual when Intel et al have PDF versions of their manuals online.
74 * Recognize "idt" or "centaur" for the -p option to ndisasm.
75 * Changed error messages back to stderr where they belong, but add an
76 -E option to redirect them elsewhere (the DOS shell cannot redirect
78 * -M option to generate Makefile dependencies (based on code from Alex
80 * %undef preprocessor directive, and -u option, that undefines a
82 * OS/2 Makefile (Mkfiles/Makefile.os2) for Borland under OS/2; from
84 * Various minor bugfixes (reported by):
85 - Dangling %s in preproc.c (Martin Junker)
86 * THERE ARE KNOWN BUGS IN SSE AND THE OTHER KATMAI INSTRUCTIONS. I am
87 on a trip and didn't bring the Katmai instruction reference, so I
88 can't work on them right now.
89 * Updated the License file per agreement with Simon and Jules to
90 include a GPL distribution clause.
94 * (Hopefully) fixed the canned Makefiles to include the outrdf2 and
96 * Renamed changes.asm to changed.asm.
100 * Fixed a bunch of instructions that were added in 0.98p3.5 which had
101 memory operands, and the address-size prefix was missing from the
104 For release 0.98p3.5:
106 * Merged in changes from John S. Fine's 0.98-J5 release. John's based
107 0.98-J5 on my 0.98p3.3 release; this merges the changes.
108 * Expanded the instructions flag field to a long so we can fit more
109 flags; mark SSE (KNI) and AMD or Katmai-specific instructions as
111 * Fix the "PRIV" flag on a bunch of instructions, and create new
112 "PROT" flag for protected-mode-only instructions (orthogonal to if
113 the instruction is privileged!) and new "SMM" flag for SMM-only
115 * Added AMD-only SYSCALL and SYSRET instructions.
116 * Make SSE actually work, and add new Katmai MMX instructions.
117 * Added a -p (preferred vendor) option to ndisasm so that it can
118 distinguish e.g. Cyrix opcodes also used in SSE. For example:
120 ndisasm -p cyrix aliased.bin
121 00000000 670F514310 paddsiw mm0,[ebx+0x10]
122 00000005 670F514320 paddsiw mm0,[ebx+0x20]
123 ndisasm -p intel aliased.bin
124 00000000 670F514310 sqrtps xmm0,[ebx+0x10]
125 00000005 670F514320 sqrtps xmm0,[ebx+0x20]
126 * Added a bunch of Cyrix-specific instructions.
128 For release 0.98p3.4:
130 * Made at least an attempt to modify all the additional Makefiles (in
131 the Mkfiles directory). I can't test it, but this was the best I
133 * DOS DJGPP+"Opus Make" Makefile from John S. Fine.
134 * changes.asm changes from John S. Fine.
137 For release 0.98p3.3:
139 * Patch from Conan Brink to allow nesting of %rep directives.
140 * If we're going to allow INT01 as an alias for INT1/ICEBP (one of
141 Jules 0.98p3 changes), then we should allow INT03 as an alias for INT3
143 * Updated changes.asm to include the latest changes.
144 * Tried to clean up the <CR>s that had snuck in from a DOS/Windows
145 environment into my Unix environment, and try to make sure than
146 DOS/Windows users get them back.
147 * We would silently generate broken tools if insns.dat wasn't sorted
148 properly. Change insns.pl so that the order doesn't matter.
149 * Fix bug in insns.pl (introduced by me) which would cause conditional
150 instructions to have an extra "cc" in disassembly, e.g. "jnz"
151 disassembled as "jccnz".
154 For release 0.98p3.2:
156 * Merged in John S. Fine's changes from his 0.98-J4 prerelease; see
157 http://www.csoft.net/cz/johnfine/
158 * Changed previous "spotless" Makefile target (appropriate for distribution)
159 to "distclean", and added "cleaner" target which is same as "clean"
160 except deletes files generated by Perl scripts; "spotless" is union.
161 * Removed BASIC programs from distribution. Get a Perl interpreter
163 * Calling this "pre-release 3.2" rather than "p3-hpa2" because of
164 John's contributions.
165 * Actually link in the IEEE output format (zoutieee.c); fix a bunch of
166 compiler warnings in that file. Note I don't know what IEEE output
167 is supposed to look like, so these changes were made "blind".
170 For release 0.98p3-hpa:
172 * Merged nasm098p3.zip with nasm-0.97.tar.gz to create a fully
173 buildable version for Unix systems (Makefile.in updates, etc.)
174 * Changed insns.pl to create the instruction tables in nasm.h and
175 names.c, so that a new instruction can be added by adding it *only*
177 * Added the following new instructions: SYSENTER, SYSEXIT, FXSAVE,
178 FXRSTOR, UD1, UD2 (the latter two are two opcodes that Intel
179 guarantee will never be used; one of them is documented as UD2 in
180 Intel documentation, the other one just as "Undefined Opcode" --
181 calling it UD1 seemed to make sense.)
182 * MAX_SYMBOL was defined to be 9, but LOADALL286 and LOADALL386 are 10
183 characters long. Now MAX_SYMBOL is derived from insns.dat.
184 * A note on the BASIC programs included: forget them. insns.bas is
185 already out of date. Get yourself a Perl interpreter for your
186 platform of choice at:
