Bug ID: 17501
Summary: Misdetected Slow_SSE4_2 cpu feature bit
Product: glibc
Version: 2.18
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: schwab@linux-m68k.org
CC: drepper.fsp at gmail dot com
Host: x86_64-*-*, i686-*-*
Several ifunc trampolines misdetect the Slow_SSE4_2 cpu feature bit due to
using the wrong offset from __cpu_features. Another place misdetects the
Fast_Unaligned_Load bit.
