Bug ID: 66497
Summary: FAIL: g++.dg/abi/aarch64_guard1.C
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: singhai at gcc dot gnu.org
Target Milestone: ---
This is a bug which requires testcase update after r224118.
The failure is like this:
FAIL: g++.dg/abi/aarch64_guard1.C -std=gnu++11 scan-tree-dump original
"_ZGVZ3foovE1x & 1"
The passing testcase at r224117 had the following
aarch64_guard1.C.003t.original: (r224117)
if ((_ZGVZ3foovE1x & 1) == 0)
but at r224118 an atomic acquiring load (type 2) is done instead (as below)
which causes the pattern match to fail.
aarch64_guard1.C.003t.original: (r224118)
if (<<cleanup_point ((int) __atomic_load_1 (&_ZGVZ3foovE1x, 2) & 1) == 0>>)
