2010-11-17Re-enable test with modifications for Neon vector changes in clang.Bob Wilson
I mistakenly thought that this was checking for vector name mangling, but it is not. Since we're no longer wrapping Neon vectors in structs, this test can just return a vector directly. There are already other tests for that, so just to make this interesting, change the test to return a struct of two vectors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119434 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

where we failed to free this buffer along one of the paths, and detangles the code a little. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119379 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Simplify some complex emission and implement correct semantics forJohn McCall
assignment to volatiles in C. This in effect reverts some of mjs's work in and around r72572. Basically, the C++ standard is quite clear, except that it lies about volatile behavior approximating C's, whereas the C standard is almost actively misleading. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119344 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-16Futher reduce the includes of our builtin headers, and teach limits.h to avoidChandler Carruth
include_next when not hosted or unavailable. This follows the pattern in stdint.h and allows these headers to work even in a freestanding configuration without a standard library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119343 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-16Fix PR8625 and correctly interpret member-calls to static members whenChandler Carruth
producing warnings. This feels really fragile, and I've not audited all other argument index-based warnings. I suspect we'll grow this bug on another warning eventually. It might be nice to adjust the argument indices when building up the attribute AST node, as we already have to remember about the 'this' argument within that code to produce correct errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119340 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
2010-11-16Rework USR generation from CXCursors to use CXStringBufsTed Kremenek
for the backing of generated USRs. This optmizes for the case when a client generates a sequence of USRs in sequence, disposing of them soon after generating them. By using a string buffer, we recycle malloc'ed memory instead of constantly malloc'ing and copying strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119338 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
