epiphany.c (epiphany_override_options): If TARGET_SOFT_CMPSF is not enabled, set flag_finite_math_only.
gcc:
* config/epiphany/epiphany.c (epiphany_override_options):
If TARGET_SOFT_CMPSF is not enabled, set flag_finite_math_only.
* config/epiphany/epiphany.md (mov<mode>cc): Don't use
reverse_condition_maybe_unordered if flag_finite_math_only is set.
gcc/testsuite:
* gcc.target/epiphany/fcmp-1.c: New test.
