>Other targets like BPF seem better to optimize g1 and g2 to f1 and f2 respectively since g1/g2 use more registers than f1/f2 and has if condition.

Yes that is a known thing we don't do ifcvt on the gimple level always; there
are many other issues about that.

f1/f2 not using maskeqz is PR 111126 (RV64 with zicond has a similar
instruction called czero.eqz.

aarch64 code gen is also kinda of odd, cmp/csel should be faster than mul. I
think it is the same issue as PR 111126 really because with the current thing
expand only tries &=- or *; does not try movcc optab.
