calls wi_fold_in_parts which checks if one of the subranges is small,

The recent fix for std::get uses a deleted overload to give better
diagnostics for out-of-range indices. This does something similar for
std::get.
Tested powerpc64le-linux. Committed to trunk.
This adds a deleted overload of std::get(const tuple&).

The problem is the buffer is too small to hold "-O" and

If __int128 is supported then __int_traits<__int128> is guaranteed to be
specialized, so we can remove the preprocessor condition inside the
std::numeric_traits<__detail::__max_size_type> specialization. Simply
using __int_traits<_Sp::__rep> gives the right answer.

This gets rid of a few gimple_expr_type uses.

I like it better with short names, there is no other code in that
script to clash with. (Also, two adjacent case branches for hg and svn
are essentialy dead now).
My previous change to vect_gen_while introduced paths which call
make_temp_ssa_name with a NULL name which isn't supported. The
following fixes that.

This patch has been pushed.
C-SKY previously used a forked print-sysroot-suffix.sh and define
CSKY_MULTILIB_DIRNAMES to specify OS multilib directories. This
patch delete the forked print-sysroot-suffix.sh and define
MULTILIB_DIRNAMES to generate same directories.

Hi,
this patch adds EAF_NOT_RETURNED flag which is determined by ipa-modref
and used both to improve its propagation (it can stop propagating flags
from call parameter to return value if EAF_NOT_RETURNED is earlier
determined for callee) and also to improve points-to constraints in

Hi Sandra,
The part of the patch to add tests for this goes on top of my base
TS29113 testsuite patch, which hasn't been reviewed or committed yet.
It is my understanding that it is not gcc policy to add xfailed test
cases for things that do not yet work. Rather, xfail is for tests that
This reorders the @{ and @relates tags, and moves the definition of the
__cpp_lib_make_unique macro out of the group, as it seems to confuse
doxygen.
