--- Comment #5 from Oleg Endo <olegendo at gcc dot gnu.org> --- This issue seems to be popping up quite often when the fsca insn is utilized (via the sincos pattern). That's the only insn which uses a `v2sf` ( vec2<float> ) and I suspect that something's going wrong there when it runs out of registers.
