Bug ID: 78921
Summary: SSE/AVX shuffle intrinsics uses builtins instead of
__builtin_shuffle
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: linux at carewolf dot com
Target Milestone: ---
The intrinsics for x86 SIMD shuffle instructions could be redeclared using
__builtin_shuffle. This would help folding and better instruction selection.
This has already been suggested on
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=29756 and is also a necessary
component of solving one part of
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78563 .
