side components. (Florian Krohm <britzel@acm.org> and Christian

6fd0eb7b07 Merged the MACOSX106 branch to the trunk. Merge command:
svn merge -r11143:HEAD svn://svn.valgrind.org/valgrind/branches/MACOSX106

There were some easy-to-resolve conflicts.

Then I had to fix up coregrind/link_tool_exe*.in -- those files had been
added independently on both the trunk and the branch, AFAICT.  I just
overwrote the trunk versions with the branch versions.

b39a007b53 Reinstating a heavily modified version of r10402. This is to do
with #190429.

This patch (originally from Jakub Jelinek) makes the redir of strlen
in ld.so on amd64-linux ld.so mandatory, but only for glibc 2.10 and
above.  For glibc-2.2 (our earliest supported version) to glibc-2.9
it is still optional.

Also, makes more verbose, the message that is printed if a mandatory
ld.so redirection on Linux cannot be set up.

Is believed to fix #190429.

2a7d944c27 A number of changes relating to syscall numbering:
- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out
  differences in the way syscall numbers are printed on different platforms.
  This gets rid of seven "DDD" fixme-style comments.

- This also meant that Darwin syscall numbers are now printed in a
  non-ambiguous way -- previously Unix, machine-dependent and diagnostic
  syscalls were all printed the same way, even though their numbers overlap.
  Now each number is prefixed with "unix", "mdep", etc.  And Mach trap
  numbers aren't printed as negative numbers now that they have a "mach"
  prefix.

- Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two
  parts, one suitable for inclusion in asm files, one suitable for inclusion
  in C files;  in both cases the latter includes the former.  This makes
  this module more like other modules that have asm-only components (eg.
  m_transtab);  it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and
  tests to be removed.

- Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed,
  and renamed some of the existing ones to make their meanings clearer.

- Added comments on the encoding of Darwin syscall numbers so it's
  possible for mortals to understand without reading the kernel code..

07045477ca Merge the DARWIN branch onto the trunk.
I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts.  So instead I just took the diff between
the branch and trunk  at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

cd13fc1af8 ppc32-linux signal handling: don't place the sigframe return stub on
the stack; instead use a stub in m_trampoline.S.  This makes it

behaviour consistent with x86-linux and amd64-linux.

f44a25e141 This module supplies various replacement functions, amongst them a
replacement for index/strchr in ld.so.  Unfortunately the replacement
functionality was actually rindex/strrchr and amazingly it has taken
about 2.5 years for anyone to notice.

This fixes the x86-linux case; ppc32-linux and ppc64-linux fixes to
follow.

4d4bc5d1f6 fixed up ppc64 assembly with .opd sections
do_syscall_for_client_WRK() needed a bigger stack to avoid the linkage area.

always use dot_prefix for label calls

not wrapping assembly with
.section ".text"
...
.previous
 - ppc64 doesn't like it... seems we can't 'stack' more than one section to pop off with .previous ?

cc8ccbbfb4 This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive).  That branch is now dead.
Please do not commit anything else to it.

For the most part the merge was not troublesome.  The main areas of
uncertainty are:

- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
  and include it in a couple of places.  Building etc seems to still
  work, but I haven't tried building the documentation.

- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
  stuff was moved from -generic to -linux after the branch was created.
  I think that is satisfactorily glued back together now.

- Regtests: although this appears to work, no .out files appear, which
  is strange, and makes it hard to diagnose regtest failures.  In
  particular memcheck/tests/x86/scalar.stderr.exp remains in a 
  conflicted state.

- amd64 is broken (slightly), and ppc32 will be unbuildable.  I'll
  attend to the former shortly.

ba3fdbc461 The strlen that ld.so uses on ppc32 causes a lot of false errors in
memcheck, and they are hard to get rid of and hard to suppress.  So
add a bootstrap strlen function and redirect to it right from the
start.  This fn only replaces the strlen in ld.so; the "normal"
redirect mechanism still replaces the strlen that glibc supplies.

This commit finally (!) makes memcheck behave sanely on ppc32.

b36f48842a Simplify the implementation of m_trampoline and the stuff that refers
to it.  Now there are no more offsets and no copying of code into the
stack.  We just redirect directly to entry points in m_syscalls.S.

This will mess up pointercheck, since the redirect targets are now in
Valgrind's address space, not the client's.  But pointercheck is hosed
anyway, and I'd rather back off to something simple whilst ppc32 is
stabilised.  When the address space management stuff is overhauled
then pointercheck may or may not get reinstated, and if it does then
the trampoline stuff will need revisiting.

f174930b23 Final commit for the initial modularisation pass:
- Broke part of m_scheduler off into a new module m_threadstate.  It
  contains ThreadState, VG_(threads)[] and some basic operations on the
  thread table.  All simple stuff, the complex stuff stays in m_scheduler.
  This avoids lots of circular dependencies between m_scheduler and other
  modules.

- Managed to finally remove core.h and tool.h, double hurrah!

- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
  include by every single C file.

- Lots of little cleanups and changes related to the above.

- I even did a small amount of documentation updating.
