2010-03-19Remove the capture, serialization, and deserialization of commentDouglas Gregor
ranges as part of the ASTContext. This code is not and was never used, but contributes ~250k to the size of the Cocoa.h precompiled header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99007 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Implement serialization and lazy deserialization of the preprocessingDouglas Gregor
record (which includes all macro instantiations and definitions). As with all lay deserialization, this introduces a new external source (here, an external preprocessing record source) that loads all of the preprocessed entities prior to iterating over the entities. The preprocessing record is an optional part of the precompiled header that is disabled by default (enabled with -detailed-preprocessing-record). When the preprocessor given to the PCH writer has a preprocessing record, that record is written into the PCH file. When the PCH reader is given a PCH file that contains a preprocessing record, it will be lazily loaded (which, effectively, implicitly adds -detailed-preprocessing-record). This is the first case where we have sections of the precompiled header that are added/removed based on a compilation flag, which is unfortunate. However, this data consumes ~550k in the PCH file for Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering this detailed preprocessing information, so it's too expensive to turn on by default. In the future, we should investigate a better encoding of this information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99002 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-16Fix header-search problems with precompiled headers, where theDouglas Gregor
presence or absence of header map arguments when using the precompiled header would cause Clang to get confused about which headers had already been included/imported, along with their controlling macros. The fundamental problem is that the serialization of the header search information was relying on the UIDs of FileEntry objects at PCH generation time and PCH load time to be equivalent, which effectively means that we had to probe the same files in the same order. Differing header map arguments caused an extra FileEntry lookup, but it's easy to imagine other minor command-line arguments triggering this problem. Header-search information is now encoded along with the source-location entry for a file, so that we register information about a file's properties as a header at the same time we create the FileEntry for that file. Fixes <rdar://problem/7743243>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98636 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98134 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-21This patch implements objective-c's 'SEL' type as a built-inFariborz Jahanian
type and fixes a long-standing code gen. crash reported in at least two PRs and a radar. (radar 7405040 and pr5025). There are couple of remaining issues that I would like for Ted. and Doug to look at: Ted, please look at failure in Analysis/MissingDealloc.m. I have temporarily added an expected-warning to make the test pass. This tests has a declaration of 'SEL' type which may not co-exist with the new changes. Doug, please look at a FIXME in PCHWriter.cpp/PCHReader.cpp. I think the changes which I have ifdef'ed out are correct. They need be considered for in a few Indexer/PCH test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89561 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-23Remove OriginalTypeParmDecl; the original type is the one specifiedJohn McCall
in the DeclaratorInfo, if one is present. Preserve source information through template instantiation. This is made more complicated by the possibility that ParmVarDecls don't have DIs, which is possibly worth fixing in the future. Also preserve source information for function parameters in ObjC method declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84971 91177308-0d34-0410-b5e6-96231b3b80d8
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
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.

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

2009-07-02Add 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
