jsji added a comment.
This is also breaking test-suites in our internal buildbots ..
This change is actually changing the default behavior: if user does NOT supply `-ffp-contract`, it becomes `-ffp-contract=on`.
So this means any code without explicitly add `-ffp-contract=off` will have `-ffp-contract=on`.
eg: -O0 will also generate FMA.
Is this intended behavior change? @mibintc @andrew.w.kaylor
