* When we see a reference to a struct, class, or union like "struct X"Douglas Gregor2009-01-095-11/+53
| | | | | | | | | | | | | | | | that is neither a definition nor a forward declaration and where X has not yet been declared as a tag, introduce a declaration into the appropriate scope (which is likely *not* to be the current scope). The rules for the placement of the declaration differ slightly in C and C++, so we implement both and test the various corner cases. This implementation isn't 100% correct due to some lingering issues with the function prototype scope (for a function parameter list) not being the same scope as the scope of the function definition. Testcase is FIXME'd; this probably isn't an important issue. Addresses <rdar://problem/6484805>. llvm-svn: 62014

* Enhance PTH 'getSpelling' caching:Ted Kremenek2009-01-091-15/+104
| | | | | | | | | | | | | | - Refactor caching logic into a helper class PTHSpellingSearch - Allow "random accesses" in the spelling cache, thus catching the remaining cases where 'getSpelling' wasn't hitting the PTH cache For -Eonly, PTH, Cocoa.h: - This reduces wall time by 3% (user time unchanged, sys time reduced) - This reduces the amount of paged source by 1112K. The remaining 1112K still being paged in is from somewhere else (investigating). llvm-svn: 62009

* Replace DeclContext's vector of ScopedDecl pointers with a linked listDouglas Gregor2009-01-094-10/+25
| | | | | | | | | | | | | | | | | | of ScopedDecls (using the new ScopedDecl::NextDeclInScope pointer). Performance-wise: - It's a net win in memory utilization, since DeclContext is now one pointer smaller than it used to be (std::vectors are typically 3 pointers; we now use 2 pointers) and - Parsing Cocoa.h with -fsyntax-only (with a Release-Asserts Clang) is about 1.9% faster than before, most likely because we no longer have the memory allocations and copying associated with the std::vector. I'll re-enable serialization of DeclContexts once I've sorted out the NextDeclarator/NextDeclInScope question. llvm-svn: 62001

| | | | | | | | | | | | | | | rewrite @class declarations that showed up within linkage specifications because those @class declarations never made it any place where the rewriter could find them. Moved all of the ObjC*Decl nodes over to ScopedDecls, so that they can live in the appropriate top-level or transparent DeclContext near the top level, e.g., TranslationUnitDecl or LinkageSpecDecl. Objective-C declarations now show up in a traversal of the declarations in a DeclContext (they didn't before!). This way, the rewriter finds all Objective-C declarations within linkage specifications. llvm-svn: 61966

* Unify the code for defining tags in C and C++, so that we alwaysDouglas Gregor2009-01-0810-124/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | introduce a Scope for the body of a tag. This reduces the number of semantic differences between C and C++ structs and unions, and will help with other features (e.g., anonymous unions) in C. Some important points: - Fields are now in the "member" namespace (IDNS_Member), to keep them separate from tags and ordinary names in C. See the new test in Sema/member-reference.c for an example of why this matters. In C++, ordinary and member name lookup will find members in both the ordinary and member namespace, so the difference between IDNS_Member and IDNS_Ordinary is erased by Sema::LookupDecl (but only in C++!). - We always introduce a Scope and push a DeclContext when we're defining a tag, in both C and C++. Previously, we had different actions and different Scope/CurContext behavior for enums, C structs/unions, and C++ structs/unions/classes. Now, it's one pair of actions. (Yay!) There's still some fuzziness in the handling of struct/union/enum definitions within other struct/union/enum definitions in C. We'll need to do some more cleanup to eliminate some reliance on CurContext before we can solve this issue for real. What we want is for something like this: struct X { struct T { int x; } t; }; to introduce T into translation unit scope (placing it at the appropriate point in the IdentifierResolver chain, too), but it should still have struct X as its lexical declaration context. PushOnScopeChains isn't smart enough to do that yet, though, so there's a FIXME test in nested-redef.c llvm-svn: 61940

* This is a large/messy diff that unifies the ObjC AST's with DeclContext.Steve Naroff2009-01-0813-169/+136
| | | | | | | | | | | | | | | - ObjCContainerDecl's (ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl), ObjCCategoryImpl, & ObjCImplementation are all DeclContexts. - ObjCMethodDecl is now a ScopedDecl (so it can play nicely with DeclContext). - ObjCContainerDecl now does iteration/lookup using DeclContext infrastructure (no more linear search:-) - Removed ASTContext argument to DeclContext::lookup(). It wasn't being used and complicated it's use from an ObjC AST perspective. - Added Sema::ProcessPropertyDecl() and removed Sema::diagnosePropertySetterGetterMismatch(). - Simplified Sema::ActOnAtEnd() considerably. Still more work to do. - Fixed an incorrect casting assumption in Sema::getCurFunctionOrMethodDecl(), now that ObjCMethodDecl is a ScopedDecl. - Removed addPropertyMethods from ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl. This passes all the tests on my machine. Since many of the changes are central to the way ObjC finds it's methods, I expect some fallout (and there are still a handful of FIXME's). Nevertheless, this should be a step in the right direction. llvm-svn: 61929

* PTH: Hook up getSpelling() caching in PTHLexer. This results in a niceTed Kremenek2009-01-081-4/+62
| | | | | | | | | | | | | | | | | | | | performance gain. Here's what we see for -Eonly on Cocoa.h (using PTH): - wall time decreases by 21% (26% speedup overall) - system time decreases by 35% - user time decreases by 6% These reductions are due to not paging source files just to get spellings for literals. The solution in place doesn't appear to be 100% yet, as we still see some of the pages for source files getting mapped in. Using -print-stats, we see that SourceManager maps in 7179K less bytes of source text (reduction of 75%). Will investigate why the remaining 25% are getting paged in. With these changes, here's how PTH compares to non-PTH on Cocoa.h: -Eonly: PTH takes 64% of the time as non-PTH (54% speedup) -fsyntax-only: PTH takes 89% of the time as non-PTH (11% speedup) llvm-svn: 61913
* PTH:Ted Kremenek2009-01-082-7/+41
| | | | | | | | | | - Added stub PTHLexer::getSpelling() that will be used for fetching cached spellings from the PTH file. This doesn't do anything yet. - Added a hook in Preprocessor::getSpelling() to call PTHLexer::getSpelling() when using a PTHLexer. - Updated PTHLexer to read the offsets of spelling tables in the PTH file. llvm-svn: 61911
