    public boolean trueBranchComesFirst

    True if the ifTrue label comes before the ifFalse label. This is used in the hope we can optimize away a branch followed by its target.

  • ConditionalTarget

    public ConditionalTarget(Label ifTrue,
     Label ifFalse,
     Language language)

    Parameters:

    ifTrue - label to jump to if this evaluates to true

    ifFalse - label to jump to if true

    language - specifies what values are true

    compileFromStack in class Target

  • emitGotoFirstBranch

    public final void emitGotoFirstBranch(CodeAttr code)

    Goto whichever of IfTrue or ifFalse is specified by trueBranchComesFirst. Normally, the goto should get optimized away as a no-op.
