Method Overview

Methods

llvm::MachineInstr* CloneMachineInstr(

Description

Find the underlying defining instruction / operand for a COPY instruction while in SSA form. Copies do not actually define values -- they move them between registers.

This method follows the definition chain for any sequence of COPY-like instructions to find whatever non-COPY-like instruction defines the copied value; or for parameters, creates a DBG_PHI on entry. May insert instructions into the entry block!\p MI The copy-like instruction to salvage.\p DbgPHICache A container to cache already-solved COPYs.

Declared at: llvm/include/llvm/CodeGen/MachineFunction.h:553
