Hi:
As discussed in [1], this patch support _Float16 under target sse2
and above, w/o avx512fp16, _Float16 type is storage only, all operations
are emulated by soft-fp and float instructions. Soft-fp keeps the intermediate
result of the operation at 32-bit precision by defaults, which may lead to

Hi!
The following testcase ICEs because we haven't verified if reduction decl
has reference type that TREE_TYPE of the reference is a complete type,
require_complete_type on the decl doesn't ensure that.

Hi!
The target data construct shouldn't affect omp_check_private, unless
the decl there is privatized (use_device_* clauses). The routine
had some code for that, but it just did continue; in a loop that looped
only if the region type is one of selected 4 kinds, so effectively resulted
in return f

Special-casing checks for in-tree gas features is unnecessary since
r17 which made configure-gcc depend on all-gas, and thus making
alternate code path in gcc_GAS_CHECK_FEATURE for in-tree gas
redundant.

of leb128 support pr

The problem here is we try to an initialized value
from a scalar constant. For vectors we need to do
a vect_dup instead. This fixes that issue by using

1. Replace scalar_int_mode with fixed_size_mode in the by-pieces
infrastructure to allow non-integer mode.
2. Rename widest_int_mode_for_size to widest_fixed_size_mode_for_size
to return QI vector mode for memset.
3. Add op_by_pieces_d::smallest_fixed_size_mode_for_size to return the
smallest integ

Another one of Gerhard's infamous testcases. We did not properly detect
and reject array elements of type CLASS as argument to an intrinsic when
it should be an array.
Regtested on x86_64-pc-linux-gnu. OK for mainline / 11-branch when it
reopens?
Thanks,

Fortran: extend check for array
I have the impression that Gerhard is a hydra: one PR down, he submits
two new ones... :-(
Anyway, here's a straightforward fix for a NULL pointer dereference for
an invalid argument to STAT. For an alternative patch by Steve see PR.

My eye was drawn to the typos below so I fixed them.

Hello,
Wanted to follow up on the CTF/BTF debug info + LTO workings.
To summarize, the current status/workflow on trunk is:
- The CTF container is written out in the ctfout.c or btfout.c via the
ctf_debug_finalize () API.
- At this time, the ctf_debug_finalize () itself is called once in

The analyzer's state purging code was overzealously purging state

false positives from -Wanalyzer-use-of-uninitialized-value.
