================
Comment at: llvm/include/llvm/CodeGen/TargetInstrInfo.h:123-125
+ /// in the function. If \p AllowVRegs is set to true then virtual register
+ /// uses are allowed as well for regalloc to opportunistically rematerialize
+ /// an instruction if all used registers happen to be available.
----------------
I don't understand why AllowVRegs needs to be a parameter. Why wouldn't it just always true?
