It compiles, but aborts immediately if you try to run it.
I didn't include ldt.c; I'm not sure how the LDT is used on AMD64. It can be
added later if necessary.
While doing this, did some 64-bit cleanness fixes:
- Added necessary intermediate casts to ULong to avoid warnings when converting
ThreadId to void* and vice versa, in vg_scheduler.c.
- Fixed VALGRIND_NON_SIMD_CALL[0123] to use 'long' as the return type.
- Fixed VALGRIND_PRINTF{,BACKTRACE} to use unsigned longs instead of unsigned
ints, as needed.
- Converted some offsets in vg_symtab2.h from "Int" to "OffT".
- Made strlen, strncat, etc, use SizeT instead of 'unsigned int' for the length
parameter.
- Couple of other minor things.
I had to insert some "#ifdef __amd64__" and "#ifndef __amd64__" guards in
places. In particular, in vg_mylibc.c, some of our syscall wrappers aren't
appropriate for AMD64 because the syscall numbering is a bit different in
places. This difference will have to be abstracted out somehow.
Also rewrote the sys_fcntl and sys_fcntl64 wrappers, as required for AMD64.
Also moved the ipc wrapper into x86, since it's not applicable for
AMD64. However, it is applicable (I think) for ARM, so it would be nice
to work out a way to share syscall wrappers between some, but not all,
archs. Hmm. Also now using the real IPC constants rather than magic
numbers in the wrapper.
Other non-AMD64-related fixes:
- ARM: fixed syscall table by accounting for the fact that syscall
numbers don't start at 0, but rather at 0x900000.
- Converted a few places to use ThreadId instead of 'int' or 'Int' for
thread IDs.
- Added both AMD64 and ARM (which I'd forgotten) entries to valgrind.spec.in.
- Tweaked comments in various places.
