Hi,
MULTIARCH_DIRNAME was removed @r196649 since the dir info had been
combined in MULTILIB_OSDIRNAMES.
But MULTIARCH_DIRNAME was re-added @r201164. With this change, the
final multiarch_dir is combined as
"aarch64-linux-gnu:aarch64-linux-gnu", which is incorrect and leads to
multiarch build fail
If you want to limit to x86_64-linux only, please do:
target { { i?86-*-linux* x86_64-*-linux* } && lp64 }
instead. Also, what advantages do you see for trying to assemble
the result? If you instead just do dg-do compile, you can drop -save-temps
from dg-options and /* { dg-final { cleanup-saved

Dependence analysis in the vectorizer assumes that all references

It also allows the builtin to be inlined for non-constant lengths.
No new regressions. Upgraded test case to handle former case.

Hi,
with the attached patch the jump over the extraction of CC into a GPR

flagged as "returns_twice" this generates slow code and prevents the
backend optimization for nonescaping transaction from working
correctly.
This fixes the fo
It's incorrect to use CMN to compare with a negated operand if the
following condition is an inequality. This is because of boundary
conditions when the negated operations overflow (or when zero), since
the flags are then not the swapped version of the comparison.
This patch restricts the pattern
