| | | | | | | multiple declarations of the function. Should fix PR3989 and <rdar://problem/6818429>. llvm-svn: 69905
* Handle corner case where clang-cc is invoked directly to compile ↵Devang Patel2009-04-232-8/+15
| | | | | | | | preprocessed source file without -main-file-name. In this case, CDDebugInfo is not able identify correct main source file becase SM.isFromMainFile() returns true for locations from header files as well as locations from main source file. This patch takes conservative approach by not emitting more then one compile unit with isMain bit set. llvm-svn: 69902

* Mark IMAGE_INFO as constant on x86_64-darwin.Daniel Dunbar2009-04-231-0/+1
| | | | | | | - This shouldn't change anything, we never actually access it, but this is consistent with llvm-gcc (and 32-bit) llvm-svn: 69880

* the logic for computing __func__ and friends is really broken:Chris Lattner2009-04-234-6/+11
| | | | | | | | | the type assigned by sema (and is visible with sizeof(__func__) for example) has nothing to do with what codegen ends up producing. We should eventually add a method on PredefinedExpr to handle this. In the meantime, just set up some framework and add some fixme's. llvm-svn: 69872
* Use std::sort instead of qsort.Daniel Dunbar2009-04-231-15/+7
| | | | | | | | | - Notably, there was a memory error here, SkipIvars does not have to be the same size as IvarsInfo. - Fariborz, please check. llvm-svn: 69850
* Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor2009-04-233-32/+51
| | | | | | | | | | | methods, class methods, and property implementations) and instead place all of these entities into the DeclContext. This eliminates more linear walks when looking for class or instance methods and should make PCH (de-)serialization of ObjCDecls trivial (and lazy). llvm-svn: 69849
* ivar layout bitmap is alive!Fariborz Jahanian2009-04-221-10/+20

* Reapply r69771, with updates & fixes:Daniel Dunbar2009-04-221-8/+21
| | | | | | | | | | | | | | | | | | | | | | Rework the shadow struct that is layed out for Objective-C classes. - Superclasses are now always laid out in their shadow structure at the first field. - Prior to this, the entire class heirarchy was flattened into a single structure which meant that alignment, padding, and bitfields were incorrect (the ASTRecordLayout was correct however, which meant our debug info didn't coincide with ivar offsets, for example). - This is still very suboptimal (for example, ivar are looked up recursively, but I believe the ivar layout itself is now at least close to correct. - <rdar://problem/6773388> error: objc[29823]: layout bitmap sliding backwards llvm-svn: 69811
* Remove lookupFieldDeclFromIvar from ObjCIvarDecl interface.Daniel Dunbar2009-04-221-2/+18
| | | | | | - This is only used by CGObjCRuntime now. llvm-svn: 69800
* Don't convert interface types (to structs) as part of CodeGenTypes.Daniel Dunbar2009-04-224-43/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - This has pros and cons, but for now the pros seem to significantly outway the con. The con is that we will always need to cast in the runtime implementation to a struct type, if we wish to access an interface directly. The pros are: - Avoid the cost of generating types which are used. Most manipulation of Objective-C objects is done through messages, and only the implementation of a class will directly access memory. Previously, we would convert the type even if it only appear as a function parameter, for example. - We don't need to worry about incomplete types, and UpdateCompletedType for interfaces is gone. - It becomes easier to narrow the interface to the shadow struct for Objective-C interfaces (so it can be eliminated). Currently the runtimes still use the CodeGenTypes machinery to generate the LLVM structure they need via ConvertTagDecl, but this can eventually be replaced. llvm-svn: 69797

* Use ComputeIvarBaseOffset instead of looking up by hand.Daniel Dunbar2009-04-221-7/+2
| | | | llvm-svn: 69789
* Merge ivar access amongst the three runtimes.Daniel Dunbar2009-04-223-147/+124
| | | | | | | | | - For now, this means we are always doing the address computations by hand instead of constructing a proper GEP. Right now, however, this is less important than having fewer entry points to dealing with Objective-C interface layout. llvm-svn: 69787

| | | | | | | | | | extern. Previously we would warn about it and ignore the attribute. This is incorrect, it should be handled as a c89 "extern inline" function.

* Explictly track tentative definitions within Sema, then hand thoseDouglas Gregor2009-04-213-25/+20
| | | | | | | | | | | | | | | tentative definitions off to the ASTConsumer at the end of the translation unit. Eliminate CodeGen's internal tracking of tentative definitions, and instead hook into ASTConsumer::CompleteTentativeDefinition. Also, tweak the definition-deferal logic for C++, where there are no tentative definitions. Fixes <rdar://problem/6808352>, and will make it much easier for precompiled headers to cope with tentative definitions in the future. llvm-svn: 69681
