bool ClangASTImporter::LayoutRecordType(
const clang::RecordDecl *record_decl, uint64_t &bit_size,
uint64_t &alignment,
llvm::DenseMap<const clang::FieldDecl *, uint64_t> &field_offsets,
llvm::DenseMap<const clang::CXXRecordDecl *, clang::CharUnits>
&base_offsets,
llvm::DenseMap<const clang::CXXRecordDecl *, clang::CharUnits>

}示例2: AddMethodsToClass
void CGObjCJit::AddMethodsToClass(void *theClass) {
// Methods need to be added at runtime. Method function pointers (IMP)
// are not available until then.
CGBuilderTy Builder(JitInitBlock);
CodeGen::CodeGenFunction CGF(CGM);
void *theMetaclass = _object_getClass(theClass);
llvm::DenseMap<const ObjCMethodDecl*, llvm::Function*>::iterator I =

while (I != MethodDefinitions.end()) {
const ObjCMethodDecl *D = I->first;
std::string TypeStr;
CGM.getContext().getObjCEncodingForMethodDecl(const_cast<ObjCMethodDecl*>(D),
TypeStr);
const char* TypeCStr = // keep in a set
MethodTypeStrings.insert(MethodTypeStrings.begin(), TypeStr)->c_str();
void *ClassObject = D->isClassMethod() ? theMetaclass : theClass;
llvm::Value *ClassArg =
llvm::Constant::getIntegerValue(ObjCTypes.ClassPtrTy,
llvm::APInt(sizeof(void*) * 8,
(uint64_t)ClassObject));
