* Convert RecordLayout::NonVirtualAlign to CharUnits. No change inKen Dyck2011-02-083-9/+16
| | | | | | functionality intended. llvm-svn: 125069
* dgregor accidentally killed this assert, but on investigation, it can fireJohn McCall2011-02-081-18/+10
| | | | | | on invalid code and we don't really care, so kill it harder. llvm-svn: 125068
* Support for objc use of property-dot syntax as receiverFariborz Jahanian2011-02-081-0/+4
| | | | | | | in liu of a class method getter. objc++ uses a different code path and is more involved (TBD). llvm-svn: 125061
* When copy-capturing values for a nested capture, use a BlockDeclRefExpr.John McCall2011-02-071-3/+11
| | | | llvm-svn: 125021
* A few more tweaks to the blocks AST representation: John McCall2011-02-0724-1060/+1279
| | | | | | | | | | | | | | | | | - BlockDeclRefExprs always store VarDecls - BDREs no longer store copy expressions - BlockDecls now store a list of captured variables, information about how they're captured, and a copy expression if necessary With that in hand, change IR generation to use the captures data in blocks instead of walking the block independently. Additionally, optimize block layout by emitting fields in descending alignment order, with a heuristic for filling in words when alignment of the end of the block header is insufficient for the most aligned field. llvm-svn: 125005

* When building with optimizations, emit thunks with available_externally ↵Anders Carlsson2011-02-062-6/+43

* Improve our uniquing of file entries when files are re-saved or areDouglas Gregor2011-02-056-42/+67
| | | | | | | | | | | | | | overridden via remapping. Thus, when we create a "virtual" file in the file manager, we still stat() the real file that lives behind it so that we can provide proper uniquing based on inodes. This helps keep the file manager much more consistent. To take advantage of this when reparsing files in libclang, we disable the use of the stat() cache when reparsing or performing code completion, since the stat() cache is very likely to be out of date in this use case. llvm-svn: 124971
* Basic implementation of inherited constructors. Only generates declarations, ↵Sebastian Redl2011-02-055-6/+281

| | | | | | | | GetOrCreateLLVMFunction so that we won't assert when building a thunk for an implicit virtual member function that is not marked used. llvm-svn: 124967
* [analyzer] Fix a false positive of the 'self' initialization checker.Argyrios Kyrtzidis2011-02-051-4/+20
| | | | | | | | | | | | | | | | | | | A common pattern in classes with multiple initializers is to put the subclass's common initialization bits into a static function that receives the value of 'self', e.g: if (!(self = [super init])) return nil; if (!(self = _commonInit(self))) return nil; It was reported that 'self' was not set to the result of [super init]. Until we can use inter-procedural analysis, in such a call, transfer the ObjCSelfInitChecker flags associated with 'self' to the result of the call. Fixes rdar://8937441 & http://llvm.org/PR9094 llvm-svn: 124940
* When the out-of-line definition differs from the declaration in the return type,Argyrios Kyrtzidis2011-02-051-1/+5
| | | | | | | | | say "out-of-line definition differ from the declaration in the return type" instead of the silly "functions that differ only in their return type cannot be overloaded". Addresses rdar://7980179. llvm-svn: 124939
* Re-land r124768, with a fix for PR9130.Anders Carlsson2011-02-055-21/+24

* -Wselector should warn on implemented selectors onlyFariborz Jahanian2011-02-041-1/+5
| | | | | | | | when selector metadata is generated, which is triggered by at least on class implementation. This is to match gcc's behavior. // rdar://8851684. llvm-svn: 124909

| | | | | | | | | | | | | | id-expression, e.g., CurrentClass<T>::member Previously, if CurrentClass<T> was dependent and not complete, we would treat it as a dependent-scoped declaration reference expression, even if CurrentClass<T> referred to the current instantiation. Fixes PR8966 and improves type checking of templates. llvm-svn: 124867
* Before checking bitfield initialization, make sure that neither theDouglas Gregor2011-02-041-0/+7

* When a function template's template parameter has a default argument,Douglas Gregor2011-02-041-2/+2
| | | | | | | | | | it's okay for the following template parameters to not have default arguments (since those template parameters can still be deduced). Also, downgrade the error about default template arguments in function templates to an extension warning, since this is a harmless C++0x extension. llvm-svn: 124855

* Implement -Woverloaded-virtual.Argyrios Kyrtzidis2011-02-032-1/+103
| | | | | | | | | | | | The difference with gcc is that it warns if you overload virtual methods only if the method doesn't also override any method. This is to cut down on the number of warnings and make it more useful like reported here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20423. If we want to warn that not all overloads are overriden we can have an additional warning like -Wpartial-override. -Woverloaded-virtual, unlike gcc, is added to -Wmost. Addresses rdar://8757630. llvm-svn: 124805
* Teach SourceManager::getLocation() how to cope with a source fileDouglas Gregor2011-02-031-18/+84
| | | | | | | | | | | | | | | | whose inode has changed since the file was first created and that is being seen through a different path name (e.g., due to symlinks or relative path elements), such that its FileEntry pointer doesn't match a known FileEntry pointer. Since this requires a system call (to stat()), we only perform this deeper checking if we can't find the file by comparing FileEntry pointers. Also, add a micro-optimization where we don't bother to compute line numbers when given the location (1, 1). This improves the efficiency of clang_getLocationForOffset(). llvm-svn: 124800

* More capturing of 'this': implicit member expressions. Getting thatJohn McCall2011-02-0310-195/+211
| | | | | | | | | | | right for anonymous struct/union members led to me discovering some seemingly broken code in that area of Sema, which I fixed, partly by changing the representation of member pointer constants so that IndirectFieldDecls aren't expanded. This led to assorted cleanups with member pointers in CodeGen, and while I was doing that I saw some random other things to clean up. llvm-svn: 124785

* Don't try to mark virtual members referenced for classes where the key functionAnders Carlsson2011-02-035-21/+25
| | | | | | | | | | | is not defined in the current translation unit. Doing so lead to compile errors such as PR9114. Instead, when CodeGen is building the vtable, don't try to emit a definition for functions that aren't marked used in the current translation unit. Fixes PR9114. llvm-svn: 124768
