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

2010-01-31Add VarDecl::isThisDeclarationADefinition(), which properly encapsulates the ↵Sebastian Redl
logic for when a variable declaration is a (possibly tentativ) definition. Add a few functions building on this, and shift C tentative definition handling over to this new functionality. This shift also kills the Sema::TentativeDefinitions map and instead simply stores all declarations in the renamed list. The correct handling for multiple tentative definitions is instead shifted to the final walk of the list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94968 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22(1) Rename getClangSubversionRevision() to getClangRevision(), andTed Kremenek
have it return a StringRef instead of an integer (to be more VCS agnostic). (2) Add getClangFullRepositoryVersion(), which contains an amalgamation of the repository name and the revision. (3) Change PCH to only emit the string returned by getClangFullRepositoryVersion() instead of also emitting the value of getClangSubversionRevision() (which has been removed). This is functionally equivalent. More cleanup to version string generation pending... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94231 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.

2009-11-11Redo how PCH handles its implicit include. Instead of treating this specially inDaniel Dunbar
the front-end (as far as the preprocessor goes), follow the usual logic of inserting the (original include path) name into the predefines buffer. This pushes the responsibility for handling this to PCH instead of the front-end. In PCH this requires being a little more clever when we diff the predefines buffers. Neither of these solutions are particularly great, I think what we eventually should do is something like gcc where we insert a special marker to indicate the PCH file, but then run the preprocessor as usual. This would be clearer and would allow us to drop the overly clever predefines handling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86806 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-11Rewrite splitLines using StringRef; this is much simpler, and also now avoidsDaniel Dunbar
tons of std::string trashing. I plan to move this and other fun string munging utilities to a StringRefExtras.h at some point if no one beats me to it. On a synthetic benchmark on x86_64, llvm-gcc actually generates code thats 10% faster using the StringRef version. gcc miscompiles the synthetic benchmark, which I'm crossing my fingers and hoping won't happen here. clang compiles the sythetic benchmark correctly (wootness), but the StringRef version is slower. Silly clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86799 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Introduce a new representation for template templateDouglas Gregor
parameters. Rather than storing them as either declarations (for the non-dependent case) or expressions (for the dependent case), we now (always) store them as TemplateNames. The primary change here is to add a new kind of TemplateArgument, which stores a TemplateName. However, making that change ripples to every switch on a TemplateArgument's kind, also affecting TemplateArgumentLocInfo/TemplateArgumentLoc, default template arguments for template template parameters, type-checking of template template arguments, etc. This change is light on testing. It should fix several pre-existing problems with template template parameters, such as: - the inability to use dependent template names as template template arguments - template template parameter default arguments cannot be instantiation However, there are enough pieces missing that more implementation is required before we can adequately test template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86777 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-23Fix integer overflow in PCHReader when reading the length of anTed Kremenek
identifier. This caused a crash when reading PCH files that contained long identifier names. The issue is that 'StrLenPtr' was previously a 'const char *', meaning the byte loaded from it would be interpretted as a signed integer. If the topmost bit was set, conversion to 'unsigned' would extend that bit, causing an overflow. The solution is to make 'StrLenPtr' an 'unsigned char *', always treating the value as an unsigned integer. This fixes: <rdar://problem/7328900> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84925 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
