[Bug target/43610] [4.5 Regression] ICE: in prepare_float_lib_cmp, at optabs.c:4392 with -fno-trapping-math and _Decimal64 comparison

------- Comment #1 from rguenth at gcc dot gnu dot org  2010-04-01 13:48 -------
Because we only have an optab for LT (reversed UNGE), but
FLOAT_LIB_COMPARE_RETURNS_BOOL is false.

Without -fno-trapping-math we use LT from the start which works.

I suppose FLOAT_LIB_COMPARE_RETURNS_BOOL should return true for decimal
float modes on x86?
