Just cast both values to const TargetRegisterClass*.

Inline asm clobber registers name
Hi all, I am currently working on AMDGPU inline assembly and encountered problem with naming clobber registers in asm constraints. It looks like by default LLVM tries to match register specified in constraint to register name of register definition in .td file but not to the AsmName for this register. For example if we have register definition: def MYReg0 : Register<"r0", 0>;

PPCTargetLowering::EmitInstrWithCustomInserter has a reference to the current MachineFunction for other purposes. Can you use MachineFunction::getRegInfo instead?

Would it be acceptable to change MachineInstr::getRegInfo from private to public so I can use it from PPCTargetLowering::EmitInstrWithCustomInserter?
