* [PCH] When serializing Stmts, keep track of when sub statements are ↵Argyrios Kyrtzidis2011-10-212-4/+58
| | | | | | | | | | | | referenced again and in such a case just write out a reference of a previously serialized Stmt, instead of serializing it all over again. This saves memory + space + [de]serializing time, and avoids blowing up memory with pathological cases. rdar://10293911 llvm-svn: 142696

* Provide half floating point support as a storage only type.Anton Korobeynikov2011-10-142-0/+2
| | | | | | Lack of half FP was a regression compared to llvm-gcc. llvm-svn: 142016

| | | | | | | | committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic. Thanks to Jeffrey Yasskin for the thorough review! llvm-svn: 141330

* Improve location fidelity of objc decls.Argyrios Kyrtzidis2011-10-042-10/+9
| | | | | | | | -Add the location of the class name to all objc container decls, not just ObjCInterfaceDecl. -Make objc decls consistent with the rest of the NamedDecls and have getLocation() point to the class name, not the location of '@'. llvm-svn: 141061
* Allow getting all source locations of selector identifiers in a ObjCMethodDecl.Argyrios Kyrtzidis2011-10-032-2/+17
| | | | | | | | | | | | | Instead of always storing all source locations for the selector identifiers we check whether all the identifiers are in a "standard" position; "standard" position is -Immediately before the arguments: -(id)first:(int)x second:(int)y; -With a space between the arguments: -(id)first: (int)x second: (int)y; -For nullary selectors, immediately before ';': -(void)release; In such cases we infer the locations instead of storing them. llvm-svn: 140989

| | | | | | | | | | | | | Instead of always storing all source locations for the selector identifiers we check whether all the identifiers are in a "standard" position; "standard" position is -Immediately before the arguments: [foo first:1 second:2] -With a space between the arguments: [foo first: 1 second: 2] -For nullary selectors, immediately before ']': [foo release] In such cases we infer the locations instead of storing them. llvm-svn: 140987

| | | | | | | | | | PreprocessingRecord's getPreprocessedEntitiesInRange. Also remove all the stuff that were added in ASTUnit that are unnecessary now that we do a binary search for preprocessed entities and deserialize only what is necessary. llvm-svn: 140063

* [libclang] When getting a source location from a file:line:col tripletArgyrios Kyrtzidis2011-09-191-13/+5
| | | | | | | check whether the requested location points inside the precompiled preamble, in which case the returned source location will be a "loaded" one. llvm-svn: 140060
* Introduce PreprocessingRecord::getPreprocessedEntitiesInRange()Argyrios Kyrtzidis2011-09-192-7/+133
| | | | | | | | | | which will do a binary search and return a pair of iterators for preprocessed entities in the given source range. Source ranges of preprocessed entities are stored twice currently in the PCH/Module file but this will be fixed in a subsequent commit. llvm-svn: 140058

* [PCH] Overhaul how preprocessed entities are [de]serialized.Argyrios Kyrtzidis2011-09-153-198/+72
| | | | | | | | | | | | | -Use an array of offsets for all preprocessed entities -Get rid of the separate array of offsets for just macro definitions; for references to macro definitions use an index inside the preprocessed entities array. -Deserialize each preprocessed entity lazily, at first request; not in bulk. Paves the way for binary searching of preprocessed entities that will offer efficiency and will simplify things on the libclang side a lot. llvm-svn: 139809

* [PCH] Fix a regression that r139441 introduced (decls were getting passedArgyrios Kyrtzidis2011-09-133-11/+28
| | | | | | | | | | | | | | | | | to the consumer without being fully deserialized). The regression was on compiling boost.python and it was too difficult to get a reduced test case unfortunately. Also modify the logic of how objc methods are getting passed to the consumer; codegen depended on receiving objc methods before the implementation decl. Since the interesting objc methods are ones with a body and such methods only exist inside an ObjCImplDecl, deserialize and pass to consumer all the methods of ObCImplDecl when we see one. Fixes http://llvm.org/PR10922 & rdar://10117105. llvm-svn: 139644
