Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
CC: jbeulich at novell dot com, ubizjak at gmail dot com
Target Milestone: ---
Target: i386,x86-64
With binutils commit:
commit 6ff00b5e12e7256738d9a4dac66e5a7745b771ea
Author: Jan Beulich <jbeul...@novell.com>

x86/Intel: correct permitted operand sizes for AVX512 scatter/gather
AVX gather insns correctly allow the element size to be specified rather
than the full vector size. Make AVX512 ones match.
