    • os/signal: increase deliver time for signal testcase · 44cacba3 
          
    This increases the time to wait for signals to be delivered in the
    TestAtomicStop testcase. When running gccgo tests on ppc64 or ppc64le,
    there are intermittent failures in this test because the wait time is
    too small.

    • Fix independent-cloneids-1.c testcase (PR88318) · c46eb979 
      The testcase uses REs like {(?n)\m_*bar[.$_]constprop[.$_]0:} to find
what functions are defined.  But, this also matches lines like
.L.bar.constprop.0:(which are used on powerpc64-linux).
The "(?n)" doesn't do anything here either.  We should use "^" here
instead of just "\m".

    • Overload std::distance and std::advance for path::iterator · 9e160526 
      Although filesystem::path::iterator is only a bidirectional iterator,
the underlying sequence has random access iterators (specifically, raw
pointers). This means std::distance and std::advance can be implemented
more efficiently than the generic versions which apply ++ and --
repeatedly.

    • require profiling support for gcc.dg/lto/20100430-1_0.c test · 5da5fefe 
      This test currently fails unexpectedly if GCC is configured with
--disable-gcov, because it requires -fprofile-arcs. This patch
fixes the issue by requiring profiling support in order to run
this test.

Tested with two compilers, one built with --disable-gcov, resulting
in the test reporting an UNSUPPORTED result; and one built with gcov
support, resulting in 2 PASS tests.

gcc/testsuite/ChangeLog:

        * gcc.dg/lto/20100430-1_0.c: Add dg-require-profiling requirement.

    • [libbacktrace] Add allocfail.sh test-case · d665cd9b 
      Add test-case that forces alloc.c functions to fail, and check whether fail
handling is robust.

This is the test-case for "[libbacktrace] Fix segfault upon allocation
failure".  Without that patch, this test-case fails like this:
...
allocfail.sh: line 71: 26041 Segmentation fault      (core dumped) \
  ./allocfail $i > /dev/null 2>&1
Unallowed fail found: 13
FAIL allocfail.sh (exit status: 1)
...

This is a seperate patch because the test-case is nontrivial.

Bootstrapped and reg-tested on x86_64.

    • libgcc: rs6000: tramp.S: fix placement of .cfi_endproc for __trampoline_setup · 5a2580b6 
      Currently, .cfi_endproc and FUNC_END(__trampoline_setup) are placed
inside the #else branch of an "#if defined (__VXWORKS__) ...", so
non-pic vxworks does not get proper CFI nor a .size directive for
__trampoline_setup. I assume there's no magic reason for that (which
would warrant a comment), so move them outside.

      The PR is about unnecessary saves of the pic base register, it shows on m32 Linux and m32/m64 Darwin.

The fix is to check that we are in a pic mode and that the picbase has actually been used.
As a bonus, some #ifdef’d TARGET_MACHO code is no longer required.
