Bug #: 50145
Summary: FAIL: gcc.dg/torture/pr50067-*.c -O* execution test on
powerpc*-*-*
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: dominiq@lps.ens.fr
CC: rguenther@suse.de
Host: powerpc*-*-*
Target: powerpc*-*-*
Build: powerpc*-*-*
gcc.dg/torture/pr50067-*.c aborts on powerpc*-*-* (see
http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg02191.html and
http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg02189.html). AFAICT this is
not a regression: they aborts also when compiled with gcc 4.4.6.

I suppose it's a big/little-endian issue with the testcase, so the expected array contents change? Making the short input array values duplicated in both bytes could fix the test (with adjusting the expected output as well) ^ permalink raw reply [flat|nested] 6+ messages in thread
