2013-01-10Error if an anonymous DiagGroup is referenced multiple times.Jordan Rose
Not only is this inefficient for TableGen, it's annoying for maintenance when renaming warning flags (unusual) or adding those flags to a group (more likely). This uses the new fix-it infrastructure for LLVM's SourceMgr/SMDiagnostic, as well as a few changes to TableGen to track more source information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172087 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-10Pulling formatFirstToken one level up.Manuel Klimek
This prepares the code for single line optimizations and changes the dependencies between single-line-formats to the indent of the first token. Conceptually, the first token is "between" the lines anyway, as the whitespace for the first token includes the previous end-of-line, which needs to be escaped when inside a preprocessor directive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172083 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-10Fixes layout of right braces.Manuel Klimek
We now decide whether a newline should go before the closing brace depending on whether a newline was inserted after the opening brace. For example, we now insert a newline before '};' in: static SomeClass WithALoooooooooooooooooooongName = { 100000000, \"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\" }; ... while not inserting a newline here: static SomeClass = { a, b, c, d, e, f, g, h, i, j, looooooooooooooooooooooooooooooooooongname, looooooooooooooooooooooooooooooong }; Also fixes the formating of (column limit 25): int x = { avariable, b(alongervariable) }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172076 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-10Fixes formatting of function calls etc inside an initializer list.Manuel Klimek
We're now formatting (column limit 25): int x = { avariable, b(alongervariable) }; This also fixes: Aaa({ int i; }, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb, ccccccccccccccccc)); ... where we would previously break after the '},'. Putting the closing curly into an extra line when there's a break directly after the first curly will be done in a subsequent patch. Paired with djasper. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172070 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-10Improvements to function type and ObjC block formatting.Daniel Jasper
Before: int (^myBlock) (int) = ^(int num) {} A<void ()>; int (*b)(int); After: int (^myBlock)(int) = ^(int num) {} A<void()>; int(*b)(int); For function types and function pointer types, this patch only makes the behavior consistent (for types that are keywords and other types). For the latter function pointer type declarations, we'll probably want to add a space after "int". Also added LangOpts.Bool = 1, so we handle "A<bool()>" appropriately Moved the LangOpts-settings to a public place for use by tests and clang-format binary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172065 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-10Fix layout of blocks inside statements.Manuel Klimek
Previously, we would not indent: SOME_MACRO({ int i; }); correctly. This is fixed by adding the trailing }); to the unwrapped line starting with SOME_MACRO({, so the formatter can correctly match the braces and indent accordingly. Also fixes incorrect parsing of initializer lists, like: int a[] = { 1 }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172058 91177308-0d34-0410-b5e6-96231b3b80d8
