public class SSACache
extends java.lang.Object

A mapping from IMethod -> SSAOptions -> SoftReference -> IR This doesn't work very well ... GCs don't do such a great job with SoftReferences ... revamp it.

Method Detail

findOrCreateIR

public IR findOrCreateIR(IMethod m,
                         Context C,
                         SSAOptions options)

Parameters:

m - a "normal" (bytecode-based) method

options - options governing ssa construction

Returns:

an IR for m, built according to the specified options. null if m is abstract or native.

Throws:

java.lang.IllegalArgumentException - if m is null

findOrCreateDU

public DefUse findOrCreateDU(IMethod m,
                             Context C,
                             SSAOptions options)

Parameters:

m - a method

options - options governing ssa construction

Returns:

DefUse information for m, built according to the specified options. null if unavailable

Throws:

java.lang.IllegalArgumentException - if m is null

findOrCreateDU

public DefUse findOrCreateDU(IR ir,
                             Context C)

Returns:

DefUse information for m, built according to the specified options. null if unavailable

Throws:

java.lang.IllegalArgumentException - if ir is null

wipe

public void wipe()

The existence of this is unfortunate.
