A recent change added UNSPEC to the CCMP patterns to stop combine optimizing the immediate in a rare case.
A recent change added UNSPEC to the CCMP patterns to stop combine optimizing
the immediate in a rare case. This requires a fix to the CCMP cost
calculation as the CCMP instruction with unspec is no longer recognized.
Fix the ccmp_1.c test by adding -ffinite-math-only so FCCMPE is emitted on
relational compares.
