be5133cb13 UDx instructions are 186+, not 286+ 
The UDx instructions are valid as far back as the #UD trap, which is
the 186, not the 286.

52dc353868 Handle is4 bytes without meaningful information in the bottom bits 
Support is4 bytes without meaningful information in the bottom bits.
This is equivalent to /is4=0 for the assembler, but makes the bottom
bits don't care for the disassembler.

21513e822f inslist.pl: deal with the new encoding format

2d31ec106a Officially specify - as the symbol for an implicit operand

*better* be a fixed operand!

9681ef4144 AVX: implement all the convert instructions... 
Make our way through the AVX instructions: conversions.
This is all I have time for now... hopefully this can service as a
generous source of examples.

4ae88e1a83 Accept the gas mnemonics "ud2a" and "ud2b"; fix ud0 
Accept the gas mnemonics "ud2a" and "ud2b" for the instructions we
call ud2 and ud1 respectively, and Intel call ud2 and undocumented :)

Also, 0F FF is ud0 regardless of prefixes, at least as far as we know.

0ab96a17d5 ndisasm: simple compare for conditional opcodes, no loop 
We had a completely unnecessary loop to test for conditional opcodes.
Since we always put the conditional opcodes at the end, we might as
well just remember where that list starts and compare against it.

extended syntax, but not always.)

0c648204e2 openwcom.mak: wmake uses & for continuation, not \ (sigh)

separators.

a4835d466c Avoid #including .c files; instead compile as separate units 
Don't #include .c files, even if they are auto-generated; instead
compile them as separate compilation units and let the linker do its
job.

73252a92ae PTEST is SSE4.1; although AMD says it's SSE5. 
Fix this when we have proper support for feature sets, or forget about
the concept entirely.

b726b04813 insns.pl: don't require whitespace before / or \

slash or backslash begins a new operator.

instruction sizes.  Add a few more AVX sample instructions.

70a13f5a37 insns.pl: support operands that serve double duty 
Sometimes assembly syntax wants to permit a single operand to serve
multiple functions; allow this.

The disassembler could really use to be smarter about those.

1e5203872d insns.dat: make even wider to make space for AVX 
The AVX instructions take more space, so add a few tab stops across
the entire file.

8597e6900c insns.dat: use compiler-generated bytecodes for AVX 
Use compiler-generated bytecodes for the AVX instruction demos.  This
should make it a lot easier for other people (HINT, HINT) to add the
instruction table.

fff5a47e65 Same some space by introducing shorthand byte codes for SSE prefixes 
Properly done, all SSE instructions which has the 66/F2/F3 opcode
multiplex need two prefixes: one to control the use of OSP and one to
control the use of REP.  However, it's a four-way select: np/66/F2/F3;
so introduce shorthand bytecodes for that purpose.

e6fb38b9f2 insns.pl: escape literal special character in regex

can be more directly taken from the manuals.

2c94c44f35 Make insnsb.c an actual compilation unit 
"make alldeps" doesn't really like it when included files end in *.c.
Instead of renaming insnsb.c to insnsb.h, make it an actual
compilation unit, since there really isn't any reason for it not to
be.

0a4d23219e insnsb.c: use 5 digits for index, not 4 
We already have indexes up to 9500, so use 5 digits instead of 4.

ff3b57c253 Make MAX_OPERANDS a parameter in insns.pl as well 
MAX_OPERANDS is present in insns.pl as well (although proper C
compilers shouldn't need this kind of zero padding.)  Make sure it's
clear to everyone.

aaa088fbf3 Remove special hacks to avoid zero bytecodes 
We can now have zero bytecodes with impunity, so remove any special
hacks we had to avoid zeroes in the bytecode.

3720f7beae Generate a byte array instead of using strings for the byte codes 
Generate a byte array instead of using C compiler strings for the byte
codes.  This has a few advantages:

- No need to special-case zero due to broken C compilers.
- Only insns.pl only ever reads the string, so we can invent our own
  syntax.
- Compaction.
- We can give it the proper, unsigned type.
