You may want to add fmin<mode>3 and fmax<mode>3 in addition to
smin<mode>3 and smax<mode>3 so it will work without -ffinite-math-only.
‘fminM3’, ‘fmaxM3’
IEEE-conformant minimum and maximum operations. If one operand is
a quiet ‘NaN’, then the other operand is returned. If both
operands are quiet ‘NaN’, then a quiet ‘NaN’ is returned. In the
case when gcc supports signaling ‘NaN’ (-fsignaling-nans) an
invalid floating point exception is raised and a quiet ‘NaN’ is
returned.
And the MIPS 6.06 manual says:
Numbers are preferred to NaNs: if one input is a NaN, but not both, the
value of the numeric input is returned. If both are NaNs, the NaN in fs
is returned.
for MAX.fmt and MIN.fmt, so they matches fmin<mode>3 and fmax<mode>3.
