Bug ID: 83707
Summary: memcmp inline expansion causing g++.dg/eh/simd-3.C to
fail on power7 -m32
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: acsawdey at gcc dot gnu.org
Reporter: acsawdey at gcc dot gnu.org
Target Milestone: ---
Target: ppc32 power7
This is apparently due to the inline expansion code that went into gcc7.
Haven't looked into what is going on yet but hopefully an easy fix.
Code looks like this:
.L8:
bl abort
.L6:
bl __cxa_begin_catch
bl __cxa_end_catch
lis 9,.LANCHOR0@ha
la 9,.LANCHOR0@l(9)
