...er file during register allocation? Namely, if a temporary value could be stored in 8 bits, why do we give it 32 bits? So, I doubt my second way to get the size of virtual register was wrong.

Hi, I wonder if there is an interface for me to access the type or size of virtual registers in the SSA form? I have scanned the MachineOperand in CodeGen part, and failed to find this kind of info for virtual registers. -- Best regards, Li Qingan -------------- next part -------------- An HTML attachment was scrubbed...

...hich is a call (MachineInstr::isCall()), I need to check the arguments of this call site. I know that the CallSite class provides good facility for this work, but the CallSite can be constructed only fromInstruction rather than MachineInstr. Is there any workaround?
