================ Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:22039 + // Move FPSW to AX. + SDValue FPSW = DAG.getCopyToReg(DAG.getEntryNode(), DL, X86::FPSW, Test, + SDValue()); ---------------- The code you copied this form was overly complicated. You can output Glue instead of MVT::i16 from XAM node and then pass that directly to FNSTSW16r in place of `FPSW, FPSW.getValue(1)`.
