Label

class Label extends AnyRef

Represent a label in the current method code. In order to support forward jumps, labels can be created without having a deisgnated target block. They can later be attached by calling anchor'.

  22. def patch (instr: Instruction): Instruction

    Return the patched instruction.

    Return the patched instruction. If the given instruction jumps to this label, replace it with the basic block. Otherwise, return the same instruction. Conditional jumps have more than one label, so they are replaced only if all labels are anchored.

  23. def patch (code: Code): Unit

    Patch the code by replacing pseudo call instructions with jumps to the given basic block.
