Benjamin Kramer 17c836c4b5 X86: Don't emit conditional floating point moves on when targeting pre-pentiumpro architectures. ... * Model FPSW (the FPU status word) as a register. * Add ISel patterns for the FUCOM*, FNSTSW and SAHF instructions. * During Legalize/Lowering, build a node sequence to transfer the comparison result from FPSW into EFLAGS. If you're wondering about the right-shift: That's an implicit sub-register extraction (%ax -> %ah) which is handled later on by the instruction selector. Fixes PR6679.
