Bug ID: 51346
Summary: Clang changed -ffp-contract flag to "on", breaking
serval client as well as SPEC2006 and SPEC2017 tests.

Version: trunk
Hardware: All
OS: Linux
Status: NEW
Severity: release blocker
Priority: P

flip '-ffp-contract' to 'on', which breaks float point comparison tests in
Clang clients like Fuchsia and Chromium. This behavior change also breaks
benchmark suites like SPEC2006 and SPEC2017 such as
`External/SPEC/CFP2006/453.povray/` test.
This breaking change need more discussion and the breakages should be resolved
before the release of clang-13.
