than just putting a value in the result register (eg. PPC has to fiddle with

- added x86-linux/core_platform.h
- factored out getting/setting of system call arguments, put it in
platform-specific part.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2685
- Added include/x86/: contains tool_arch.h, Makefile.am, .cvsignore.
- Added coregrind/x86/state.c. Contains some arch-specific code for dealing
with x86 registers -- eg. setting up the baseBlock, loading/saving the whole
register state. It is compiled into coregrind/x86/libarch.a and linked via
${VG_ARCH} with the core.
Relatedly, also added coregrind/x86/{core_arch.h,core_arch_asm.h}.
- Correspondingly abstracted the register state out of ThreadState. This
affected every place that touches registers, and there are a lot of them.
(Eventually all the register touching should be abstracted out in an
arch-neutral way, but not yet; one step at a time.)
- Added some declarations about register loading/saving functions to core.h;
all architectures will have to provide these functions.
- Rejigged the build system so that the arch-specific stuff is all done via
${VG_ARCH}, rather than naming e.g. x86/ directly. Appropriate -I arguments
are used so that all the headers are found, etc.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2656
- corrected a few mistakes, eg. when printing them out, in prototypes
- made printing of "%p(%s)" args consistent
- removed 'sizeof_struct_user_fpxregs_struct' from PRE(ptrace)/POST(ptrace)
- allowing for the two different versions of open()

Also fixed execve() so that it works better with .in_place.
Also added a regression test for --trace-children=yes (there were none!)

- removed various things that are no longer used
- made (module-)local some things that were global
- improved the formatting in places
Removed about 160 lines of code, and non-trivially reduced the number
of global entities.

This fixes bug #86000 because shmat is no longer treated as blocking
and it is therefore no longer possible for two threads to try and use
the same address for the shared memory segment.

Also fix nanosleep so that it only marks the returned time as defined

requires padding of the address space around calls to io_setup in order
to constrain the kernel's choice of address for the I/O context.
Based on patch from Scott Smith <scott-kde@gelatinous.com> with various
enhancements, this fixes bug #83060.

- removed an unnecessary VG_(unmap_range)() call in do_brk() -- the
VG_(munmap)() just before it does it anyway.
- inlined mprotect_segment() and munmap_segment() because it's more concise and
easier to understand that way.
- a couple of minor formatting changes
- added and cleaned up a couple of comments
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2469
add a segment mapping to the segment skip-list, and then often the caller of
VG_(mmap) would do another one for the same segment, just to change the SF_*
flags. Now VG_(mmap) gets passed the appropriate SF_* flags so it can do it
directly. This results in shorter, simpler code, and less work at runtime.
Also, strengthened checking in VG_(mmap), POST(mmap), POST(mmap2) -- now if the
result is not in the right place, it aborts rather than unmapping and
continuing. This is because if it's not in the right place, something has
gone badly wrong.

the current reserved area, which effectively acts as a hard limit. The
setrlimit system call now simply updates the emulated limits as best
as possible - the hard limit is not allowed to move at all and just
returns EPERM if you try and change it.
This should stop reductions in the soft limit causing assertions when
valgrind tries to allocate descriptors from the reserved area.

renamed some related variables. The old names still work, for backwards
compatibility, but they're not documented.
