示例1: handleTOCUpdate
bool CFPatch::handleTOCUpdate(codeGen &gen) {
// Annoying, pain in the butt case...
assert(target->type() == TargetInt::BlockTarget);
Target<block_instance *> *t = static_cast<Target<block_instance *> *>(target);

return gen.codeEmitter()->emitTOCJump(t->t(), gen);
else if (type == Call)
return gen.codeEmitter()->emitTOCCall(t->t(), gen);
else {
assert(0);
return false;
}
}示例2: applyPLT
bool CFPatch::applyPLT(codeGen &gen, CodeBuffer *) {
// We should try and keep any prefixes that were on the instruction.
// However... yeah, right. I'm not that good with x86. So instead
// I'm copying the code from emitCallInstruction...
if (target->type() != TargetInt::BlockTarget) {
return false;
}
// And can only handle calls right now. That's a TODO...
if (type != Call &&
type != Jump) {
return false;
}

Target<block_instance *> *t = static_cast<Target<block_instance *> *>(target);

gen.setFunction(const_cast<func_instance *>(func));
// We can (for now) only jump to functions
func_instance *callee = tb->entryOfFunc();

// We need a RegisterSpace for this. Amusingly,
// we want to use the RegisterSpace corresponding to the
// entry of the callee, as it doesn't matter what's live
// here.
