Field Detail

positive

public final boolean positive

For if branches, positive is true. For if0 branches, positive is false.

value

public final VOperand value

The value being branched on. For if branches, the branch will be taken if value is non-zero. For if0 branches, the branch will be taken if value is zero.

target

public final VLabelRef<VCodeLabel> target

The code label that will be executed next if the branch is taken.
