If we don't have cmov, X87 compares write to FPSW and we need to move the bits to EFLAGS to use as JCC/SETCC/CMOV conditions. Previously this was done by calling ConvertCmpIfNecessary in multiple places which would emit the extra code for the FNSTSW, a shift, a truncate, and a SAHF instructions. Isel would then select trunc+X86ISD::CMP to a FUCOM instruction that produces FPSW. This patch centralizes all of the handling into a single custom isel handler. This allows us to remove ConvertCmpIfNecessary and a couple target specific ISD opcodes. Differential Revision: https://reviews.llvm.org/D73863 |
