Probably need to make the FCMP and FCMPE ISD opcodes return true for isTargetStrictFPOpcode(). This done by making the opcodes larger than a specific constant. I’m on my phone so I don’t remember the exact name.



================
Comment at: llvm/lib/Target/AArch64/AArch64InstrInfo.td:3562
 
-defm FCMPE : FPComparison<1, "fcmpe">;
 defm FCMP  : FPComparison<0, "fcmp", AArch64fcmp>;
----------------
Do these need mayRaiseFPException?
