Hi:
This patch is about to add define_insn_and_split to convert avx512
mask mov back to pblendv instructions when mask operand is (lt: reg
const0_rtx).
Bootstrapped and regtested on x86_64-linux-gnu{-m32,}.
Ok for trunk?

Hi:
This patch is about to Fold __builtin_ia32_pblendvb128 (a, b, c) as
VEC_COND_EXPR (c < 0, b, a), similar for float version but with
mask operand VIEW_CONVERT_EXPR to same sized integer vectype.
After folding, blendv related patterns can be redefined as
vec_merge since all elements of mask

To simplify PHI-OPT and future improvements to it in most
(but not all) cases, using match-and-simplify simplifies how
much code is needed to be added.
This depends on the following two patches:

This copies the optimization that is done in phiopt for
"x < 0 ? ~y : y to (x >> 31) ^ y" into match.pd. The code
for phiopt is kept around until phiopt uses match.pd (which
I am working towards).

phi-opt-10.c and phi-opt-7.c both depend on currently that some ssa name
versions are one digit long which is not always correct. This fixes the
problem by detecting digits rather than just using '.'.
Committed as obvious after a bootstrap/test.
Thanks,

GNU gettext introduced this change[0] in version 0.19.8 to fix
gettext detection with musl libc, since it does not define these
internal symbols.
This allows gcc to build with musl gettext rather than falling back
to the bundled version.

Hi Harald,
I meant to deal with this myself since I am the guilty party. However, the
last two weeks have been taken up by a house move and so gfortran has been
on the backburner.
The patch looks good and seems to do the job - OK for master and 11-branch.
Thanks a million for dealing with it!

This isn't a patch to gcc, please stop posting non-technical content to this

Instead of some of the more manual optimizations inside phi-opt,
it would be good idea to do a lot of the heavy lifting inside match
and simplify instead. In the process, this moves the three simple
