Constructor Detail

LowQuadSSA

public LowQuadSSA(LowQuadSSI code)

Creates a LowQuadSSA object from a LowQuadSSI object.

LowQuadSSA

protected LowQuadSSA(HMethod method,
                     Quad quads)

Create a new code object given a quadruple representation of the method instructions.

Method Detail

clone

public HCodeAndMaps<Quad> clone(HMethod newMethod)

Clone this code representation. The clone has its own copy of the quad graph.

WARNING: does not preserve derivation or allocation info.

Specified by:

clone in class Code

getName

public String getName()

Return the name of this code view.

Specified by:

getName in class Code

Returns:

the string "low-quad-ssa"

codeFactory

public static HCodeFactory codeFactory(HCodeFactory hcf)

Return a code factory for LowQuadSSA, given a code factory for LowQuadSSI.
effects: if hcf is a code factory for LowQuadSSI, then creates and returns a code factory for LowQuadSSA. Else passes hcf to LowQuadSSI.codeFactory(), and reattempts to create a code factory for LowQuadSSA from the code factory returned by LowQuadSSI.

codeFactory

public static HCodeFactory codeFactory()

Return a code factory for LowQuadSSA, using the default code factory for LowQuadSSI
