Bug ID: 29112
Summary: Miscompiles in test-suite with AVX512F
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86
Assignee: unassignedb...@nondot.org
Reporter: mku...@google.com
CC: elena.demikhov...@intel.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
The following 5 tests fail when built with AVX512F:
test-suite :: MultiSource/Applications/JM/ldecod/ldecod.test
test-suite :: MultiSource/Applications/SPASS/SPASS.test
test-suite :: MultiSource/Applications/lambda-0.1.3/lambda.test
test-suite :: MultiSource/Benchmarks/MallocBench/gs/gs.test
test-suite :: SingleSource/UnitTests/Vector/SSE/Vector-sse.stepfft.test
I don't know about the other 4, but I've bisected the ldecod failure to
r274613.
To be more precise, with r274613 we get a sigill, but manually applying the fix
from r276347 gets us to a segfault, like in trunk.
