Bug ID: 24147
Summary: test/CodeGen/AMDGPU/infinite-loop-evergreen.ll doesn't
terminate on Phase 2 or 3 of release
Product: new-bugs
Version: 3.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs

Classification: Unclassified
This occurred for Mips but doesn't look Mips specific at first glance.
As per the summary, Phase 1 (gcc) builds work as intended but Phase 2 and 3
(both just-built clangs) builds fail to terminate.
It seems the test is expected to call llvm_unreachable() however
llvm_unreachable() is not guaranteed to terminate the program. One possible
implementation for NDEBUG builds is to hint to the compiler that it can omit
the code path.
