2010-10-24Simplify and "robust-ify" the way that CXXRecord references point to the ↵Argyrios Kyrtzidis
definition data when loaded from PCH. Temporary disable 'test/PCH/chain-cxx.cpp' until a better way to fix it is in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117234 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-22In the presence of using declarations, we can find the same classDouglas Gregor
members in class subobjects of different types. So long as the underlying declaration sets are the same, and the declaration sets involve non-instance members, this is not an ambiguity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117163 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22Fix a horrible bug in all dataflow analyses that use CFGRecStmtVisitor ↵Ted Kremenek
(including live variables analysis). We shouldn't recurse into CompoundStmts since they are already inlined in the CFG. This could result in bogus dead stores warnings (among other things). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117162 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-22After discussion with Doug and John, I am revertingFariborz Jahanian
the patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117159 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22Substantially revise how clang computes the visibility of a declaration toJohn McCall
more closely parallel the computation of linkage. This gets us to a state much closer to what gcc emits, modulo bugs, which will undoubtedly arise in abundance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117147 91177308-0d34-0410-b5e6-96231b3b80d8

statement expressions, //rdar: //8540501 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117146 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22When we perform name lookup for a template, we may end up finding anDouglas Gregor
ambiguous name where none of the declarations found are actually templates. In this case, make sure we clear out the ambiguous-path data when recomputing the lookup result kind. Fixes PR8439. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117112 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22Tidy up MIPS_linkage name. Provide it only if it does not match regular ↵Devang Patel
name, otherwise it confuses debugger. This is tested by local.C in llvmgcc testsuite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117107 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22When performing name lookup for a namespace definition, only look intoDouglas Gregor
the current context's redeclaration context, ignoring using directives. Fixes PR8430. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117097 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-21Tweak diagnostics for redeclaration of a @property in a class extension ↵Ted Kremenek
where the redelcaration and original declaration have the 'readwrite' attribute. This is a common case, and we can issue a more lucid diagnostic. Fixes <rdar://problem/7629420>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117045 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Implement the integral promotion rules for the C++0x char16_t andDouglas Gregor
char32_t character types and enable built-in overloaded operator candidates for these types. Fixes PR8432. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117038 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Diagnose the declaration of template template parameters thatDouglas Gregor
themselves have no template parameters. This is actually a restriction due to the grammar of template template parameters, but we choose to diagnose it in Sema to provide better recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117032 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Always treat 'main' as an extern "C" function, so that we detectDouglas Gregor
redeclarations of main appropriately rather than allowing it to be overloaded. Also, disallowing declaring main as a template. Fixes GCC DejaGNU g++.old-deja/g++.other/main1.C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117029 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Tweak the ObjCAtSyncChecker to assume that a mutex is non-nil after checking ↵Ted Kremenek
that it is nil. Otherwise we can get false paths where a second @synchronized using the mutex can have a bogus warning. Fixes <rdar://problem/8578650>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117016 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Improve the implementation of libclang's token-annotation logic forDouglas Gregor
entities in the preprocessing record. Previously, we would only end up getting the first token of a preprocessing record annotated correctly. For example, given #include "foo.h" we would only get the '#' annotated as an inclusion directive; the 'include' and '"foo.h"' tokens would be given the general 'processing directive' annotation. Now, we get proper annotations for entities in the preprocessing record. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117001 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-21Previously, the printf warnings would say your arguments type was 'int' when ↵Ted Kremenek
it was really a 'char' or a 'short'. This fixes that and allows the hints to suggest 'h' modifiers for small ints. Patch by Justin Bogner! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116996 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-20Extend the preprocessing record and libclang with support forDouglas Gregor
inclusion directives, keeping track of every #include, #import, etc. in the translation unit. We keep track of the source location and kind of the inclusion, how the file name was spelled, and the underlying file to which the inclusion resolved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116952 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-20Fix handling of property and ivar lookup in typo correction; the twoDouglas Gregor
kinds of lookup into Objective-C classes were tangled together, a situation that was compounded by automatically synthesized ivars. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116907 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-20Introduce a simple cache for unqualified typo corrections, so that weDouglas Gregor
don't repeatedly loop through identifiers, correcting the same typo'd identifier over and over again. We still bail out after 20 typo corrections, but this should help improve performance in the common case where we're typo-correcting because the user forgot to include a header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116901 91177308-0d34-0410-b5e6-96231b3b80d8
