2013-02-14merge hasCLanguageLinkage and isExternC. Keep the shorter name.Rafael Espindola
I added hasCLanguageLinkage while fixing some language linkage bugs some time ago so that I wouldn't have to check all users of isExternC. It turned out to be a much longer detour than expected, but this patch finally merges the two again. The isExternC function now implements just the standard notion of having C language linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175119 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-14Add a getLanguageLinkage method to VarDecls and FunctionDecls. Use it to fixRafael Espindola
some cases where functions with no language linkage were being treated as having C language linkage. In particular, don't warn in extern "C" { static NonPod foo(); } Since getLanguageLinkage checks the language linkage, the linkage computation cannot use the language linkage. Break the loop by checking just the context in the linkage computation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175117 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-13An attempt to make the search algorithm easier to understand.Manuel Klimek
- clear ownership: the SpecificBumpPtrAllocator owns all StateNodes - this allows us to simplify the memoization data structure into a std::set (FIXME: figure out whether we want to use a hash based data structure). - introduces StateNode as recursive data structure, instead of using Edge and the Seen-map combined to drill through the graph - using a count to stabilize the penalty instead of relying on the container - pulled out a method to forward-apply states in the end This leads to a ~40% runtime decrease on Nico's benchmark. Main FiXME is that the parameter lists of some function get too long. I'd vote for either pulling the Queue etc into the Formatter proper, or creating an inner class just for the search algorithm. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175051 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-12Accept over-qualified constructor in MSVC emulation modeDmitri Gribenko
MSVC accepts this: class A { A::A(); }; Clang accepts regular member functions with extra qualification as an MS extension, but not constructors. This changes the parser to defer rejecting qualified constructors so that the same Sema logic can apply to constructors as regular member functions. This also improves the error message when MS extensions are disabled (in my opinion). Before it was: /Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers A::A(); ~~~~ ^ 1 error generated. After: /Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A' A::A(); ~~~^ 1 error generated.

2013-02-12Formatter: Correctly format stars in `sizeof(int**)` and similar places.Nico Weber
This redoes how '*' and '&' are classified as pointer / reference markers when followed by ')', '>', or ','. Previously, determineStarAmpUsage() marked a single '*' and '&' followed by ')', '>', or ',' as pointer or reference marker. Now, all '*'s and '&'s preceding ')', '>', or ',' are marked as pointer / reference markers. Fixes PR14884. Since only the last '*' in 'int ***' was marked as pointer before (the rest were unary operators, which don't reach spaceRequiredBetween()), spaceRequiredBetween() now had to be thought about handing multiple '*'s in sequence. Before: return sizeof(int * *); Type **A = static_cast<Type * *>(P); Now: return sizeof(int**); Type **A = static_cast<Type **>(P); While here, also make all methods of AnnotatingParser except parseLine() private.
