I believe the problem you ascribe to this bug is fixed. Note that we do not
generate minss for the given example because "<=" is not the operation of the
minss instruction; it performs "<". Which is relevant for "+0.0 < -0.0".
We *ought* to emit minss with -ffast-math, but that should happen via
noce_try_minmax invoking the sminsf3 pattern, rather than special-casing
this in the back-end. Open a separate PR for that if you like.
But on the bright side, we at least generate a conditional move sequence:
cmpless %xmm1, %xmm0
andps %xmm0, %xmm2
andnps %xmm1, %xmm0
orps %xmm2, %xmm0
