2009-07-22Fix a couple recent ABI regressions noticed during code review (fallout from ↵Steve Naroff
the ObjC type system rewrite). It's unfortunate that the mangling includes the low-level structs. Nevertheless, we need this for binary compatibility with GCC. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76755 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say ↵Steve Naroff
pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective). This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-). This patch also adds Type::isObjCBuiltinType(). This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75808 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the attribute-related methods of Decl.Argyrios Kyrtzidis
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext. This commit touches a lot of files since call sites for these methods are everywhere. I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74501 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-29Improve code generation for function template specializations:Douglas Gregor
- Track implicit instantiations vs. the not-yet-supported explicit specializations - Give implicit instantiations of function templates (and member functions of class templates) linkonce_odr linkage. - Improve name mangling for function template specializations, including the template arguments of the instantiation and the return type of the function. Note that our name-mangling is improved, but not correct: we still don't mangle substitutions, although the manglings we produce can be demangled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74466 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-13Simplify mangleFunctionDecl by unnesting a crazy condition. This fixesChris Lattner
the check for extern "c" system headers, which should prevent functiondecls from being mangled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73311 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-30initial support for __[u]int128_t, which should be basicallyChris Lattner
compatible with VC++ and GCC. The codegen/mangling angle hasn't been fully ironed out yet. Note that we accept int128_t even in 32-bit mode, unlike gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70464 91177308-0d34-0410-b5e6-96231b3b80d8

by anything yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69343 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-16Fix a crash bug when comparing overload quality of conversion operators with ↵Sebastian Redl
conversion constructors. Remove an atrocious amount of trailing whitespace in the overloaded operator mangler. Sorry, couldn't help myself. Change the DeclType parameter of Sema::CheckReferenceInit to be passed by value instead of reference. It wasn't changed anywhere. Let the parser handle C++'s irregular grammar around assignment-expression and conditional-expression. And finally, the reason for all this stuff: implement C++ semantics for the conditional operator. The implementation is complete except for determining lvalueness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69299 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-21fix several problems with asm renaming, by pulling it into the mangling code:Chris Lattner
1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo") 2. multiple definitions were conflicting, they weren't getting merged. 3. the code was duplicated in several places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67442 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Create a new TypeNodes.def file that enumerates all of the types,Douglas Gregor
giving them rough classifications (normal types, never-canonical types, always-dependent types, abstract type representations) and making it far easier to make sure that we've hit all of the cases when decoding types. Switched some switch() statements on the type class over to using this mechanism, and filtering out those things we don't care about. For example, CodeGen should never see always-dependent or non-canonical types, while debug info generation should never see always-dependent types. More switch() statements on the type class need to be moved over to using this approach, so that we'll get warnings when we add a new type then fail to account for it somewhere in the compiler. As part of this, some types have been renamed: TypeOfExpr -> TypeOfExprType FunctionTypeProto -> FunctionProtoType FunctionTypeNoProto -> FunctionNoProtoType There shouldn't be any functionality change... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65591 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Improve merging of function declarations. Specifically:Douglas Gregor
- When we are declaring a function in local scope, we can merge with a visible declaration from an outer scope if that declaration refers to an entity with linkage. This behavior now works in C++ and properly ignores entities without linkage. - Diagnose the use of "static" on a function declaration in local scope. - Diagnose the declaration of a static function after a non-static declaration of the same function. - Propagate the storage specifier to a function declaration from a prior declaration (PR3425) - Don't name-mangle "main" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65360 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20We must always mangle attribute overloadable functions; even if in aDaniel Dunbar
system header. - Prevents a codegen crash when anything used anything in tgmath! :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65200 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-13Add basic support for C++ name mangling according to the Itanium C++Douglas Gregor
ABI to the CodeGen library. Since C++ code-generation is so incomplete, we can't exercise much of this mangling code. However, a few smoke tests show that it's doing the same thing as GCC. When C++ codegen matures, we'll extend the ABI tester to verify name-mangling as well, and complete the implementation here. At this point, the major client of name mangling is in the uses of the new "overloadable" attribute in C, which allows overloading. Any "overloadable" function in C (or in an extern "C" block in C++) will be mangled the same way that the corresponding C++ function would be mangled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64413 91177308-0d34-0410-b5e6-96231b3b80d8
