64-bit support for ndisasm. This is very much an initial attempt, and
there are guaranteed to be bugs in the code. However, some *very*
preliminary testing seems to indicate it's not completely off-base.
64-bit support required some major changes to regs.dat; clean some of
it up (re-introduce patterns, where appropriate) and allow a single
register to belong to multiple disassembly classes; also keep track
of the x86 register number again.
CR8 is not special in any way as far as the assembler is concerned. It's
listed as having a special form in the Intel documentation, but that is
only because there are no other CRs which require a REX prefix.
MOV to CR8 is special in the sense that it's a non-serializing
instruction, but that's irrelevant to the assembler.
Furthermore, it's totally unclear how TRs should be handled in long mode;
there are no CPUs which uses TRs which also have long mode, so the easiest
is to simply mark those instructions NOLONG.
Finally, add PRIV to some privileged instructions.
We can actually test for the options being accepted, rather than try
to test for gcc; this handles differences between gcc versions as well
as compilers with a similar command line set.
Apparently configure was generating config.h, and nothing ever actually
included it. Include it in nasm.h as well as compiler.h, and in
rdoff/rdlar.h which uses these macros.
There appears to be no use of HAVE_* macros in any file that doesn't
have nasm.h included; in fact, so far the only use has been in
rdoff/rdlar.h.
Move anything compiler-specific to "compiler.h".
There was an unguarded use of __attribute__(()) in outmacho.c; also
require gcc 4+ for __builtin_ctlz(). Speed up the open-coded version, too.
- Remove obsolete types like "uint32"; use "uint32_t" consistently.
- Make sure we include <inttypes.h> where needed.
- Header file guards should be FOO_H or SUBDIR_FOO_H; _FOO_H infringes
on the C implementation's namespace and should only be used when
writing libc!
- Change a few "int8_t" back to "char" where appropriate. There are
a lot more places where that should be done, though.
- Clean up the check for getuid/getgid in rdoff/rdlar.h.
It's become custom to create a script called autogen.sh, which creates
all the auto-generated files using all the appropriate auto* tools when
run, so one doesn't have to worry about checking them into the repository.
This seems like a good idea, follow suit.
Change symbols from saa to explicitly allocated.
macho_layout_symbols: new function to sort symbols and renumber.
adjust symtab output accordingly
fixup relocs after renumbering
add relocation debugging routines.
