2010-11-19Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein
than a Token that holds the same information all in one easy-to-use package. There's no technical reason to prefer the former -- the information comes from a Token originally -- and it's clumsier to use, so I've changed the code to use tokens everywhere. Approved by clattner git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119845 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Refactoring of Diagnostic class.Argyrios Kyrtzidis
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119730 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18In some situations, TemplateArgumentLoc wasn't setting TypeSourceLoc (seeCraig Silverstein
http://llvm.org/bugs/show_bug.cgi?id=8558). This patch fixes it. Thanks to rjmccall for all the coaching! Approved by rjmccall git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119697 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Calculate the value kind of an expression when it's created andJohn McCall
store it on the expression node. Also store an "object kind", which distinguishes ordinary "addressed" l-values (like variable references and pointer dereferences) and bitfield, @property, and vector-component l-values. Currently we're not using these for much, but I aim to switch pretty much everything calculating l-valueness over to them. For now they shouldn't necessarily be trusted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119685 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17a metric ton of refactoring later, Sema::getLocationOfStringLiteralByte Chris Lattner

2010-11-17For an Objective-C @synthesize statement, e.g.,Douglas Gregor
@synthesize foo = _foo; keep track of the location of the ivar ("_foo"). Teach libclang to visit the ivar as a member reference. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119447 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Fix source-range information for Objective-C properties. Previously,Douglas Gregor
we were just getting a range covering only the property name, which is certainly not correct (and broke token annotation, among other things). Also, teach libclang about the relationship between @synthesize/@dynamic and @property, so we get property name and cursor-reference information for @synthesize and @dynamic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119409 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Re-work the handling of implicit 'this' arguments and silly GCC-style attributeChandler Carruth
argument indexes. This handles the offsets in a consistent manner for all of the attributes which I saw working with these concepts. I've also added tests for the attribute that motivated this: nonnull. I consolidated the tests for format attributes into one file, and fleshed them out a bit to trigger more of the warning cases. Also improved the quality of some of the diagnostics that occur with invalid argument indices. The only really questionable change here is supporting the implicit this argument for the ownership attribute. I'm not sure it's really a sensible concept there, but implemented the logic for consistency. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119339 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-16Change CXTranslationUnit to not directly cast to an ASTUnit*,Ted Kremenek
but to wrap both an ASTUnit and a "string pool" that will be used for fast USR generation. This requires a bunch of mechanical changes, as there was a ton of code that assumed that CXTranslationUnit and ASTUnit* were the same. Along with this change, introduce CXStringBuf, which provides an llvm::SmallVector<char> backing for repeatedly generating CXStrings without a huge amount of malloc() traffic. This requires making some changes to the representation of CXString by renaming a few fields (but keeping the size of the object the same). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119337 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Have CXXDeleteExpr::getDestroyedType return the actual destroyed typeCraig Silverstein
in more situations. In particular, for code like template<class T> void Fn() { T* x; delete x; } getDestroyedType() will now return T rather than T*, as it would before this change. On the other hand, for code like this: template<class T> void Fn() { T x; delete x; } getDestroyedType() will return an empty QualType(), since it doesn't know what the actual destroyed type would be. Previously, it would return T. OKed by rjmccall git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119334 91177308-0d34-0410-b5e6-96231b3b80d8
