computeSourceLocationForBlockAndInstruction

public static ISourceLocation computeSourceLocationForBlockAndInstruction(IFlowgraph cfg,
                                                          IBasicBlock b,
                                                          int instructionIndex)

Helper method that will use debug op code information to deduce a source location from an instruction offset in a Block in a IFlowgraph.

Parameters:

cfg - IFlowgraph containing the specified Block.

b - Block containing the instruction to deduce a ISourceLocation for.

instructionIndex - Offset in the specified Block of the instruction to deduce a ISourceLocation for.

Returns:

The deduced ISourceLocation.
