* Substantially alter the design of the Objective C type AST by introducingJohn McCall2010-05-152-27/+22
| | | | | | | | | | | | | | | | | | | | | ObjCObjectType, which is basically just a pair of one of {primitive-id, primitive-Class, user-defined @class} with a list of protocols. An ObjCObjectPointerType is therefore just a pointer which always points to one of these types (possibly sugared). ObjCInterfaceType is now just a kind of ObjCObjectType which happens to not carry any protocols. Alter a rather large number of use sites to use ObjCObjectType instead of ObjCInterfaceType. Store an ObjCInterfaceType as a pointer on the decl rather than hashing them in a FoldingSet. Remove some number of methods that are no longer used, at least after this patch. By simplifying ObjCObjectPointerType, we are now able to easily remove and apply pointers to Objective-C types, which is crucial for a certain kind of ObjC++ metaprogramming common in WebKit. llvm-svn: 103870
* Implement semantic analysis and an AST representation for the namedDouglas Gregor2010-05-154-0/+5
| | | | | | | | | | | | return value optimization. Sema marks return statements with their NRVO candidates (which may or may not end up using the NRVO), then, at the end of a function body, computes and marks those variables that can be allocated into the return slot. I've checked this locally with some debugging statements (not committed), but there won't be any tests until CodeGen comes along. llvm-svn: 103865
* Recognize when the named return value optimization applies in aDouglas Gregor2010-05-152-0/+2
| | | | | | | | | | "return" statement and mark the corresponding CXXConstructExpr as elidable. Teach CodeGen that eliding a temporary is different from eliding an object construction. This is just a baby step toward NRVO. llvm-svn: 103849

* Rework when and how vtables are emitted, by tracking where vtables areDouglas Gregor2010-05-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "used" (e.g., we will refer to the vtable in the generated code) and when they are defined (i.e., because we've seen the key function definition). Previously, we were effectively tracking "potential definitions" rather than uses, so we were a bit too eager about emitting vtables for classes without key functions. The new scheme: - For every use of a vtable, Sema calls MarkVTableUsed() to indicate the use. For example, this occurs when calling a virtual member function of the class, defining a constructor of that class type, dynamic_cast'ing from that type to a derived class, casting to/through a virtual base class, etc. - For every definition of a vtable, Sema calls MarkVTableUsed() to indicate the definition. This happens at the end of the translation unit for classes whose key function has been defined (so we can delay computation of the key function; see PR6564), and will also occur with explicit template instantiation definitions. - For every vtable defined/used, we mark all of the virtual member functions of that vtable as defined/used, unless we know that the key function is in another translation unit. This instantiates virtual member functions when needed. - At the end of the translation unit, Sema tells CodeGen (via the ASTConsumer) which vtables must be defined (CodeGen will define them) and which may be used (for which CodeGen will define the vtables lazily). From a language perspective, both the old and the new schemes are permissible: we're allowed to instantiate virtual member functions whenever we want per the standard. However, all other C++ compilers were more lazy than we were, and our eagerness was both a performance issue (we instantiated too much) and a portability problem (we broke Boost test cases, which now pass). Notes: (1) There's a ton of churn in the tests, because the order in which vtables get emitted to IR has changed. I've tried to isolate some of the larger tests from these issues. (2) Some diagnostics related to implicitly-instantiated/implicitly-defined virtual member functions have moved to the point of first use/definition. It's better this way. (3) I could use a review of the places where we MarkVTableUsed, to see if I missed any place where the language effectively requires a vtable. Fixes PR7114 and PR6564. llvm-svn: 103718

* Rework our handling of temporary objects within the conditions ofDouglas Gregor2010-05-061-1/+2
| | | | | | | | | | | | | | | | | | | if/switch/while/do/for statements. Previously, we would end up either: (1) Forgetting to destroy temporaries created in the condition (!), (2) Destroying the temporaries created in the condition *before* converting the condition to a boolean value (or, in the case of a switch statement, to an integral or enumeral value), or (3) In a for statement, destroying the condition's temporaries at the end of the increment expression (!). We now destroy temporaries in conditions at the right times. This required some tweaking of the Parse/Sema interaction, since the parser was building full expressions too early in many places. Fixes PR7067. llvm-svn: 103187

* Introduce a limit on the depth of the macro instantiation backtraceDouglas Gregor2010-05-042-23/+74
| | | | | | | | | | | | | | printed in a diagnostic, similar to the limit we already have on the depth of the template instantiation backtrace. The macro instantiation backtrace is limited to 10 "instantiated from:" diagnostics; when it's longer than that, we'll show the first half, then say how many were suppressed, then show the second half. The limit can be changed with -fmacro-instantiation-limit=N, and turned off with N=0. This eliminates a lot of note spew with libraries making use of the Boost.Preprocess library. llvm-svn: 103014
