- Factored out the remaining arch-specific code from vg_libpthread.c.
- Also fixed up the build process for x86/libpthread.c, which was done
wrongly in the previous commit.

of using an assembly hack to find the stack pointer at startup, we find it from
argv. It's much simpler, avoids linking games, is platform independent, and
works on PPC.

delivered that the thread state is temporarily changed from WaitMX or WaitCV
to Running while the signal handler is running. The original state is then
restored when the handler returns.
This patch forces the associated_mx and associated_cv values to be cleared
at the same time and the original values restored afterwards. Without this
the scheduler state will not be considered sane while the handler is running.
This is based on a patch from Kenneth Schalk and fixes a problem he had
with posting to a semaphore in a signal handler. It also allows a couple
of assertions in the scheduler sanity check to be uncommented.
BUG: 72082
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2778
- removed some assumptions that arch==x86 in Makefile.am files
- removed ume_arch.h; moved its contents into ume.h. There was no need for
these to be separate.
- moved ume_go.c into an x86/ subdir; gave it the more meaningful name
jmp_with_stack.c in the process (the corresponding function also got the name
change)

- move LDT stuff out of core, into x86-linux specific stuff. Some of it
(VG_(do_useseg)()?) may be really x86-specific, rather than
x86/linux-specific, but that can be fixed later if it's really shared with
another OS.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2748
- 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
- add a new file x86/x86_private.h, a header for the x86-specific stuff that is
not seen by the core.
- move some LDT function decls into x86_private.h.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2683
- move some LDT constants into the x86-specific code.
- abstract out uses of LDT and TLS in vg_scheduler into the x86-specific code.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2682
- moved a lot of the baseBlock initialisation into x86/, including all the
VGOFF variables, and all the x86 asm helper functions.

Mackerras's work.
- introduced arch-neutral macros for getting the instruction/frame/stack
pointers.
- renamed ExeContext.eips as ExeContext.ips
- renamed esp/ebp/eip to sp/fp/ip in several related files and arch-neutralised
various comments
- introduced arch-neutral macros for walking the stack
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2663
- 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.

cause the stack to be marked as executable in order for them to work.
All assembler files have also had a declaration added so that the
object they generate will be marked as not needing an executable stack.

Doesn't fix "make distcheck", however, because this happens:
/usr/bin/ld: cannot open linker script file ../../coregrind/x86/stage2.lds:
No such file or directory
For some reason I can't work out, that file is built when you make in a CVS
tree, or manually from a "make dist" tarball, but not when you "make
distcheck".
