2013-01-04Add __has_feature support to detect if clang supports the explicit "atomic" ↵Ted Kremenek
keyword for ObjC properties. Fixes <rdar://problem/12953378>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171504 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04NSErrorChecker: remove quoting the parameter name in the diagnostic until we ↵Ted Kremenek
actually include it's name. This is a possible regression of moving to using ImplicitNullDerefEvent. Fixing this for real (including the parameter name) requires more plumbing in ImplicitNullDerefEvent. This is just a stop gap fix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171502 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-04Let the formatter ignore UnwrappedLines containing errors.Daniel Jasper
This prevents code like: namespace { class Foo { Foo( }; } // comment from causing segfaults (see llvm.org/PR14774). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171495 91177308-0d34-0410-b5e6-96231b3b80d8

The line information was changed when emitting debug information for all the DeclRefExprs and we should change it back to get ready for PopClenupBlocks called from FinishFunction. rdar://11562117 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171493 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-03Warn on unused auto variables.Rafael Espindola
To do so we have to wait until we know that the type of a variable has been deduced. Sema::FinalizeDeclaration is the first callback that is used for decl with or without initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171458 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-03[analyzer] Rename callback EndPath -> EndFunctionAnna Zaks
This better reflects when callback is called and what the checkers are relying on. (Both names meant the same pre-IPA.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171432 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02DiagnosticIds: Fix offset/ID calculation, no impact outside this code.Argyrios Kyrtzidis
Patch by Will Dietz: Minor touchup so the values of Offset/ID reflect their intention. Previously, the sum (Offset+ID) was correct, but Offset/ID individually were wrong. Caught by investigating unsigned overflow reported by -fsanitize=integer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171421 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-02Fixes multiple formatting bugs.Manuel Klimek
Fixes: - incorrect handling of multiple consecutive preprocessor directives - crash when trying to right align the escpaed newline for a line that is longer than the column limit - using only ColumnLimit-1 columns when layouting with escaped newlines inside preprocessor directives git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171401 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Don't allow line breaks after template parameters.Daniel Jasper
This fixes llvm.org/PR14786. We will need to split there as a last resort, but that should be done consistently independent of whether the type is a template type or not. Before: template <typename T> aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaa<T> ::aaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa); After: template <typename T> aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaa<T>::aaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171400 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Format */& as binary operator if followed by a unary operator.Daniel Jasper
This fixes llvm.org/PR14687. Also fixes segfault for lines starting with * or &. Before: a *~b; *a = 1; // <- this segfaulted After: a * ~b; *a = 1; // no segfault :-) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171396 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Fixes use of unescaped newlines when formatting preprocessor directives.Manuel Klimek
This is the first step towards handling preprocessor directives. This patch only fixes the most pressing issue, namely correctly escaping newlines for tokens within a sequence of a preprocessor directive. The next step will be to fix incorrect format decisions on #define directives. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171393 91177308-0d34-0410-b5e6-96231b3b80d8
