    • 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".


	PR testsuite/88318
	* gcc.dg/independent-cloneids-1.c: Use ^ not \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.

	PR libstdc++/71044 (partial)
	* include/bits/fs_path.h (__path_iter_distance, __path_iter_advance):
	New friend functions to implement std::distance and std::advance more
	efficiently.

    • 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.

    • rs6000 - Fix PR target/88343 · be611c9c 
      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.
