2009-06-14Sink the BuiltinInfo object from ASTContext into theChris Lattner
preprocessor and initialize it early in clang-cc. This ensures that __has_builtin works in all modes, not just when ASTContext is around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73319 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-15A C++ member function always has either weak linkage (if it's inline or ↵Anders Carlsson
defined inline) or strong linkage (other cases). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71873 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-12push GlobalDecl through enough of the CodeGenModule interfacesChris Lattner
to allow us to support generation of deferred ctors/dtors. It looks like codegen isn't emitting a call to the dtor in member-functions.cpp:test2, but when it does, its body should get emitted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71594 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-05When defining a function whose type has no prototype, make an effortChris Lattner
to go back and clean up existing uses of the bitcasted function. This is not just an optimization: it is required for correctness to get always inline functions to work, see testcases in function-attributes.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70971 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-03PR4133: fix always_inline implementation to be consistent with gcc.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70786 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Improve compatibility with GCC regarding inline semantics in GNU89Douglas Gregor
mode and in the presence of __gnu_inline__ attributes. This should fix both PR3989 and PR4069. As part of this, we now keep track of all of the attributes attached to each declaration even after we've performed declaration merging. This fixes PR3264. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70292 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Fix handling of C99 "extern inline" semantics when dealing withDouglas Gregor
multiple declarations of the function. Should fix PR3989 and <rdar://problem/6818429>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69905 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69849 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Don't convert interface types (to structs) as part of CodeGenTypes.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69797 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Fix some mishandling of the attr(gnu_inline) mode when used withChris Lattner
extern. Previously we would warn about it and ignore the attribute. This is incorrect, it should be handled as a c89 "extern inline" function. Many thanks to Matthieu Castet for pointing this out and beating me over the head until I got it. PR3988: extern inline function are not externally visible git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69756 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-21Explictly track tentative definitions within Sema, then hand thoseDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69681 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14Refactor how attributes are set on values.Daniel Dunbar
- Pull out SetCommonAttributes, which handles the things common to aliases, methods, functions, and variables. - Pull out SetLLVMFunctionAttributesForDefinition, which handles the LLVM attributes which we only want to apply to a definition (like noinline and alwaysinline). - Kill SetGVDeclarationAttributes (inlined into SetFunctionAttributes and specialized). - Kill SetFunctionAttributesForDefinition (inlined into sole caller). - Inline SetGVDefinitionAttributes into SetMethodAttributes and specialize. - Rename SetGVDefinitionAttributes to SetFunctionDefinitionAttributes. This is supposed to be a no functionality change commit, but I may have made a mistake. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69036 91177308-0d34-0410-b5e6-96231b3b80d8
