示例1: if

codeGen &gen,
int &shift,
bool ®enerate) {
codeBufIndex_t start = gen.getIndex();

// BufferElement. Update it now with our current address.
buf->updateLabel(labelID_, addr_ - gen.startAddr(), regenerate);
// Get the easy bits out of the way
gen.copy(buffer_);
if (patch_) {
// Now things get interesting
if (!patch_->apply(gen, buf)) {
