Pseudo-instruction that overwrites its input register
...with code which assumes it is equivalent to save P before 'ldw r1:r2,P' or after. I tried adding "@earlyclobber $ptrreg" as a Constraint, but that just leads to an assertion failure during codegen (I assume because @earlyclobber is for output ports) void llvm::MachineOperand::setIsEarlyClobber(bool): Assertion `isReg() && IsDef && "Wrong MachineOperand accessor"' failed. Thanks, Gergo
