MIRSplitRanges

public MIRSplitRanges()

Method Detail

newExecution

public CompilerPhase newExecution(IR ir)

Return this instance of this phase. This phase contains no per-compilation instance fields.

Overrides:: newExecution in class CompilerPhase

Parameters:: ir - not used
Returns:: this

getName

public final String getName()

Return the name of this phase

Specified by:: getName in class CompilerPhase

Returns:: "Live Range Splitting"

perform

public final void perform(IR ir)

The main method.

We split live ranges for registers around PEIs which have catch blocks. Suppose we have a PEI s which uses a symbolic register r1. We must ensure that after register allocation, r1 is NOT assigned to a scratch location in s, since this would mess up code in the catch block that uses r1.

So, instead, we introduce a new temporary r2 which holds the value of r1. The live range for r2 spans only the instruction s. Later, we will ensure that r2 is never spilled.

TODO: This could be implemented more efficiently.

Specified by:: perform in class CompilerPhase

Parameters:: ir - the governing IR

splitAllLiveRanges

private static void splitAllLiveRanges(Instruction s,
                                       HashMap<Register,Register> newMap,
                                       IR ir,
                                       boolean rootOnly)

Split the live ranges of all register operands of an instruction

Parameters:: s - the instruction to process; newMap - a mapping from symbolics to temporaries; ir - the containing IR; rootOnly - only consider root operands?

findOrCreateTemp

private static RegisterOperand findOrCreateTemp(RegisterOperand rOp,
                                                HashMap<Register,Register> map,
                                                IR ir)

Find or create a temporary register to cache a symbolic register.

Parameters:: rOp - the symbolic register; map - a mapping from symbolics to temporaries; ir - the governing IR

insertMoveBefore

private static void insertMoveBefore(RegisterOperand r2,
                                     RegisterOperand r1,
                                     Instruction s)

Insert an instruction to move r1 into r2 before instruction s

insertMoveAfter

private static void insertMoveAfter(RegisterOperand r2,
                                    RegisterOperand r1,
                                    Instruction s)

Insert an instruction to move r1 into r2 after instruction s
