* Perform two more constructor/destructor code-size optimizations:John McCall2010-02-238-49/+252
| | | | | | | | | | | | | | | | 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. llvm-svn: 96842
* Implement crazy destructor name lookup semantics differently inDouglas Gregor2010-02-231-14/+56
| | | | | | | | | | C++98/03 and C++0x, since the '0x semantics break valid C++98/03 code. This new mess is tracked by core issue 399, which is still unresolved. Fixes PR6358 and PR6359. llvm-svn: 96836

* Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor2010-02-219-36/+106
| | | | | | | | fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. llvm-svn: 96766
* Implement support for parsing pseudo-destructor expression with a ↵Douglas Gregor2010-02-218-46/+103
| | | | | | | | | | | | nested-name-specifier, e.g., typedef int Int; int *p; p->Int::~Int(); This weakens the invariant that the only types in nested-name-specifiers are tag types (restricted to class types in C++98/03). However, we weaken this invariant as little as possible, accepting arbitrary types in nested-name-specifiers only when we're in a member access expression that looks like a pseudo-destructor expression. llvm-svn: 96743
* A constructor template cannot be used to copy to an object of the same class ↵Douglas Gregor2010-02-211-1/+2
| | | | | | type (per C++ [class.copy]p3). Make sure that includes copies that involve a derived-to-base conversion. Fixes PR6141. llvm-svn: 96742
* Implement AST import for C++ member functions, including constructors, ↵Douglas Gregor2010-02-211-5/+47
| | | | | | destructors, and conversions. Unfortunately, this cannot be tested yet, since we don't have C++ PCH support. llvm-svn: 96741

* Collect the code that imports all of the members of a declaration context ↵Douglas Gregor2010-02-211-27/+14
| | | | | | into a single function, ImportDeclContext. Use it rather than explicit loops. No functionality change. llvm-svn: 96739
* Implement PCH support for C++ namespaces.Douglas Gregor2010-02-212-0/+28

* Commiting a revert from dgregor of a bit of destructor logic until we canChandler Carruth2010-02-211-17/+11
| | | | | | | figure out how not to break lots of code using this. See PR6358 and PR6359 for motivating examples. FIXME's left in the code and the test. llvm-svn: 96733
* Make Decl::isOutOfLine() virtual, and use that to determine when definitionsChandler Carruth2010-02-212-12/+13
| | | | | | | are for out of line declarations more easily. This simplifies the logic and handles the case of out-of-line class definitions correctly. Fixes PR6107. llvm-svn: 96729
* Clang really intends to reject attribute 'warn_unused_result' on Objective-C ↵Ted Kremenek2010-02-211-1/+1
