False dependency happens when destination is only updated by
pternlog. There is no false dependency when destination is also used
in source. So either a pxor should be inserted, or input operand
should be set with constraint '0'.
Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.

This patch implements another of Uros' suggestions, to investigate a
insvti_lowpart_1 pattern to improve TImode parameter passing on x86_64.
In PR 88873, the RTL the middle-end expands for passing V2DF in TImode
is subtly different from what it does for V2DI in TImode, sufficiently so
that my
Following Uros' suggestion, this patch adds support for AVX512VL's
vpro[lr][dq] instructions to the recently added scalar-to-vector (STV)
enhancements to handle DImode and SImode rotations by a constant.
For the test cases:
unsigned long long rot1(unsigned long long x) {
return (x>>1) |
Description: adding a ci in a github repo. Everytime a user will do a PR to
master branch or releases branches, it will activate the ci on their repo.
for example: https://github.com/talregev/gcc/pull/1. Can help users to
verify their own changes before submitting a patch.

Hi,
dumps of profile_counts are quite hard to interpret since they are 64bit fixed
point
values. In many cases one looks at a single function and it is better to think
of
basic block frequency, that is how many times it is executed each invocatoin.
