2009-10-22When building types from declarators, instead of building two types (one forJohn McCall
the DeclaratorInfo, one for semantic analysis), just build a single type whose canonical type will reflect the semantic analysis (assuming the type is well-formed, of course). To make that work, make a few changes to the type system: * allow the nominal pointee type of a reference type to be a (possibly sugared) reference type. Also, preserve the original spelling of the reference type. Both of these can be ignored on canonical reference types. * Remove ObjCProtocolListType and preserve the associated source information on the various ObjC TypeLocs. Preserve the spelling of protocol lists except in the canonical form. * Preserve some level of source type structure on parameter types, but canonicalize on the canonical function type. This is still a WIP. Drops code size, makes strides towards accurate source location representation, slight (~1.7%) progression on Cocoa.h because of complexity drop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18When performing template-substitution into a type, don't just replace theJohn McCall
TemplateTypeParmType with the substituted type directly; instead, replace it with a SubstTemplateTypeParmType which will note that the type was originally written as a template type parameter. This makes it reasonable to preserve source information even through template substitution. Also define the new SubstTemplateTypeParmType class, obviously. For consistency with current behavior, we stringize these types as if they were the underlying type. I'm not sure this is the right thing to do. At any rate, I paled at adding yet another clause to the don't-desugar 'if' statement, so I extracted a function to do it. The new function also does The Right Thing more often, I think: e.g. if we have a chain of typedefs leading to a vector type, we will now desugar all but the last one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84412 91177308-0d34-0410-b5e6-96231b3b80d8

TypeLoc class names to be $(Type classname)Loc. Rewrite the visitor. Provide skeleton implementations for all the new TypeLocs. Handle all cases in PCH.

2009-10-17Merge the "types" and "declarations" blocks in the precompiled headerDouglas Gregor
format, so that we don't end up with multiple declaration and types blocks. Also, fix a few obscure bugs with PCH loading and generation: - If the DeclIDs DenseMap reallocates while we are writing a declaration (due to recursively writing other declarations), we could end up writing a bad ID to ExternalDefinitions. - When loading an ArrayLoc (part of DeclaratorInfo), we need to set the size expression to NULL if no size expression was provided. PCH -> AST rewriting is still partly broken, unfortunately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84293 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-05Basic support for representing elaborated type specifiersJohn McCall
directly in the AST. The current thinking is to create these only in C++ mode for efficiency. But for now, they're not being created at all; patch to follow. This will let us do things like verify that tags match during template instantation, as well as signal that an elaborated type specifier was used for clients that actually care. Optimally, the TypeLoc hierarchy should be adjusted to carry tag location information as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81057 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
2009-07-07Make ASTContext explicitly keep track of the declaration for the CDouglas Gregor
FILE type, rather than using name lookup to find FILE within the translation unit. Within precompiled headers, FILE is treated as yet another "special type" (like __builtin_va_list). This change should provide a performance improvement (not verified), since the lookup into the translation unit declaration forces the (otherwise unneeded) construction of a large hash table. More importantly, with precompiled headers, the construction of that table requires deserializing most of the top-level declarations from the precompiled header, which are then unused. Fixes PR 4509. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74911 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-07Introduce the notion of "Relocatable" precompiled headers, which are builtDouglas Gregor
with a particular system root directory and can be used with a different system root directory when the headers it depends on have been installed. Relocatable precompiled headers rewrite the file names of the headers used when generating the PCH file into the corresponding file names of the headers available when using the PCH file.

2009-07-02Add support for retrieving the Doxygen comment associated with a givenDouglas Gregor
declaration in the AST. The new ASTContext::getCommentForDecl function searches for a comment that is attached to the given declaration, and returns that comment, which may be composed of several comment blocks. Comments are always available in an AST. However, to avoid harming performance, we don't actually parse the comments. Rather, we keep the source ranges of all of the comments within a large, sorted vector, then lazily extract comments via a binary search in that vector only when needed (which never occurs in a "normal" compile). Comments are written to a precompiled header/AST file as a blob of source ranges. That blob is only lazily loaded when one requests a comment for a declaration (this never occurs in a "normal" compile). The indexer testbed now supports comment extraction. When the -point-at location points to a declaration with a Doxygen-style comment, the indexer testbed prints the associated comment block(s). See test/Index/comments.c for an example. Some notes: - We don't actually attempt to parse the comment blocks themselves, beyond identifying them as Doxygen comment blocks to associate them with a declaration. - We won't find comment blocks that aren't adjacent to the declaration, because we start our search based on the location of the declaration. - We don't go through the necessary hops to find, for example, whether some redeclaration of a declaration has comments when our current declaration does not. Similarly, we don't attempt to associate a \param Foo marker in a function body comment with the parameter named Foo (although that is certainly possible). - Verification of my "no performance impact" claims is still "to be done". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74704 91177308-0d34-0410-b5e6-96231b3b80d8
