Bug ID: 95733
Summary: Building on PowerPC 64 Tests Fail With GCC 11
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
Assignee: unassigned at gcc dot gnu.org
Reporter: xerofoify at gmail dot com
Target Milestone: ---
After building gcc as such:
../gcc/configure --enable-lanuages=c,c++ --enable-threads -disable-multilibs
--enable-checking=yes --prefix=/home/xerofoify/obdjir
it fails on running tests with make -k check with:
=== libgomp Summary ===
# of expected passes 7764
# of expected failures 4
# of unsupported tests 573

OpenMP should be enabled by default with C++ and therefore this seems to be a
regression.
