示例1: Walker
extern "C" void* j3ResolveSpecialStub() {
JavaThread *th = JavaThread::get();
void* result = NULL;
// Lookup the caller of this class.
vmkit::StackWalker Walker(th);
++Walker; // Remove the stub.
vmkit::FrameInfo* FI = Walker.get();
assert(FI->Metadata != NULL && "Wrong stack trace");
JavaMethod* caller = (JavaMethod*)FI->Metadata;
// Lookup the method info in the constant pool of the caller.
uint16 ctpIndex = caller->lookupCtpIndex(FI);
assert(ctpIndex && "No constant pool index");
JavaConstantPool* ctpInfo = caller->classDef->getConstantPool();
CommonClass* cl = 0;
const UTF8* utf8 = 0;
Signdef* sign = 0;
ctpInfo->resolveMethod(ctpIndex, cl, utf8, sign);
UserClass* lookup = cl->isArray() ? cl->super : cl->asClass();
assert(lookup->isInitializing() && "Class not ready");
JavaMethod* callee =
lookup->lookupSpecialMethodDontThrow(utf8, sign->keyName, caller->classDef);

// Compile the found method.
result = callee->compiledPtr();
// Update the entry in the constant pool.
ctpInfo->ctpRes[ctpIndex] = result;
