> LoongArch: Implement scalar isinf, isnormal, and isfinite via fclass
>
> Doing so can avoid loading FP constants from the memory. It also
> partially fixes PR 66262 as fclass does not signal on sNaN.
>
> gcc/ChangeLog:
>
> * config/loongarch/loongarch.md (extendsidi2): Add ("=r", "f")
> alternative and use movfr2gr.s for it. The spec clearly states
> movfr2gr.s sign extends the value to GRLEN.
> (fclass_<fmt>): Make the result SImode instead of a floating
> mode. The fclass results are really not FP values.
> (FCLASS_MASK): New define_int_iterator.
> (fclass_optab): New define_int_attr.
> (<FCLASS_MASK:fclass_optab><ANYF:mode>): New define_expand
> template.
>
> gcc/testsuite/ChangeLog:
>
> * gcc.target/loongarch/fclass-compile.c: New test.
> * gcc.target/loongarch/fclass-run.c: New test.
