| * The branch distance is a signed code-unit offset, which we need to |
| * double to get a byte offset. |
| * |
| * Unlike most opcodes, this one is allowed to branch to itself, so |
| * our "backward branch" test must be "<=0" instead of "<0". Because |
| * we need the V bit set, we'll use an adds to convert from Dalvik |
| * offset to byte offset. |
