This patch to libiberty adds support for strnlen if it is not already

I rebuilt the Makefile dependencies. This revealed that maint-tool

dwarf2.def, so I fixed maint-tool.
I also rebuilt functions.texi, which had not bee

Hello,
a while ago Andrew Stubbs posted a patch to use NEON registers
and instructions to perform 64-bit integer shifts:
http://gcc.gnu.org/ml/gcc-patches/2012-05/msg01645.html
As Andrew no longer works on ARM, I've now picked this up and
reworked it a bit:
- Updated for current mainline changes
This patch to libbacktrace marks the test functions with the unused
attribute. This avoids producing a compilation warning when building
the test on a system that does not support libbacktrace. Bootstrapped
and ran libbacktrace testsuite on x86_64-unknown-linux-gnu. Committed
to mainline.

This needs an entry in gcc-4.8/changes.html, of course.

Well, as summarized in the code below, the problem seems to be the
redundant overload of std::tr1::pow(double,double).
... And the patch.

Ah. I'm open for suggestion on a better name, or I can come up with a
new one.
I'll indeed add documentation as soon as there's some kind of

This patch to libbacktrace adds some support for mingw. The executable
is opened with O_BINARY. The fcntl function is not called.
Bootstrapped and ran libbacktrace testsuite on
x86_64-unknown-linux-gnu. Committed to mainline.

Thanks. I think I would like some clarity

They don't. The problem is that it conflicts with ::pow(double,double).

Hello world,
pretty self-explanatory. No test case because there is no change
in behavior. OK for trunk?

The infrastructure for gcc.dg/vect tests determines whether the default
is for tests to be compile-only or compile plus execute. Tests that
should not be executed use { dg-do compile }, but no test should use
{ dg-do run }. This patch removes { dg-do run} from pr52298.c.
Tested on arm-none-eabi
In most cases a test that requires ARM NEON should use effective target
arm_neon, which means that flags run for all tests include NEON support.
The result is cached the first time it is checked for a multilib.
Vectorization tests, when run for ARM, add flags to support NEON if it's
OK to do so, b
Seventeen tests in gcc.dg/vect that use vect_multiple_sizes have checks
similar to:
/* { dg-final { scan-tree-dump-times "can't determine dependence" 2 "vect" {
xfail vect_multiple_sizes } } } */
/* { dg-final { scan-tree-dump-times "can't determine dependence" 4 "vect" {
target vect_multiple_si
Test gcc.dg/vect/fast-math-pr35982.c uses xfail in a dg-final check when
it should instead skip the check for that effective target. Tested on
arm-none-eabi for a variety of test multilibs, checked in on trunk as
obvious. I'll backport to 4.6 when the branch is open.
