Hi.
This patch fixes the bug 113842.
I cannot yet add a test with this patch since it requires using
try/catch which is not yet merged in master.
Thanks for the review.

Hi Lulu,
I'm proposing to backport r14-4674 "LoongArch: Delete macro definition
ASM_OUTPUT_ALIGN_WITH_NOP." to releases/gcc-12 and releases/gcc-13. The

1. Strictly speaking, the old ASM_OUTPUT_ALIGN_WITH_NOP macro may cause
a correctness issue.

The v*_fp16_xN_1.c tests on Arm have been unstable since they were
added. This is not a problem with the tests themselves, or even the

Hi Tobias, Thomas,
this patch adds support for Fortran to use arrays and struct(record) types in
OpenACC reductions.
There is still some shortcomings in the current state, mainly that only
explicit-shaped arrays can be used (like its C counterpart). Anything else is

Hi All,
This adds two new debug counter to aid in debugging early break code.
- vect_force_last_exit: when reached will always force the final loop exit.
- vect_skip_exit: when reached will skip selecting the current candidate exit
as the loop exit.

There's a bug in vectorizable_live_operation that restart_loop is defined
