Bug ID: 64065
Summary: [5 Regression] CP2K miscompilation at -O3 -flto
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: Joost.VandeVondele at mat dot ethz.ch
Current trunk miscompiles cp2k at ' -flto=jobserver -fuse-linker-plugin
-fno-prefetch-loop-arrays -O3 -march=native -funroll-loops -ffast-math'
The last known good revision is r217995 and first bad is r218036
lto and -O3 are needed. As this involves lto, I don't think I can reduce the
problem, I might try to identify a precise commit.
