◆ salvageCopySSA()

auto MachineFunction::salvageCopySSA	(	MachineInstr &	MI,
		DenseMap< Register, DebugInstrOperandPair > &	DbgPHICache
	)

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. Labelling a COPY-like instruction with an instruction number is to be avoided as it makes value numbers non-unique later in compilation. 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! MI The copy-like instruction to salvage. DbgPHICache A container to cache already-solved COPYs.

Returns: An instruction/operand pair identifying the defining value.

Create substitutions for any tracked values in Old, to point at New.

Needed when we re-create an instruction during optimization, which has the same signature (i.e., def operands in the same place) but a modified instruction type, flags, or otherwise.

If the two instructions are not the same opcode, limit which operands to examine for substitutions to the first N operands by setting MaxOperand.

◆ viewCFG()

viewCFG - This function is meant for use from the debugger.

You can just say 'call F->viewCFG()' and a ghostview window should pop up from the program, displaying the CFG of the current function with the code for each basic block inside. This depends on there being a 'dot' and 'gv' program in your path.
