--- Comment #9 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- Although it seems that (1)-(5) in #3 are interesting points, they are almost optimizations. I guess that programs with frequent FP mode switchings are simply rare in real world and would be a bit special or even pathological in the first place. I like the idea of mode switching without __fpscr_values even if it requires more instructions on SH4. Now SH4 is a fairy old core and is not for heavy FP computations anyway. I think that it won't impact the real working set. It looks to me that Christian's patch is the way to go.
