2013-01-09Formatter: Add support for @interface.Nico Weber
Previously: @interface Foo + (id)init; @end Now: @interface Foo + (id)init; @end Some tweaking remains, but this is a good first step. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171995 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-09Handle static functions being redeclared in function scope.Rafael Espindola
Fixes pr14861. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171978 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Enables layouting unwrapped lines around preprocessor directives.Manuel Klimek
Previously, we'd always start at indent level 0 after a preprocessor directive, now we layout the following snippet (column limit 69) as follows: functionCallTo(someOtherFunction( withSomeParameters, whichInSequence, areLongerThanALine(andAnotherCall, B withMoreParamters, whichStronglyInfluenceTheLayout), andMoreParameters), trailing); Note that the different jumping indent is a different issue that will be addressed separately. This is the first step towards handling #ifdef->#else->#endif chains correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171974 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Only align after assignments on the top level.Daniel Jasper
This fixes llvm.org/PR14870 and we no longer mess up: template <typename T1, typename T2 = char, typename T3 = char, typename T4 = char> void f(); It removes the nice aligment for assignments inside other expressions, but I am not sure those are actually practically relevant. If so, we can fix those later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171966 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Don't simply give up when exceeding 80cols, choose an "ok" option.Daniel Jasper
This addresses llvm.org/PR14847. We can now format something like: int aaaaaaaaaaaaaaaaaaaaaaaaaaa = // aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaiaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb; clang-format unavoidably exceeds the column limit, but does not just flush everything into a single line. Moreover, it tries to minimize the number of characters beyond the column limit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171964 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes llvm.org/PR14846. Before: template <typename T> void aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa( int aaaaaaaaaaaaaaaaa); After: template <typename T> void aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa( int aaaaaaaaaaaaaaaaa); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171963 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Allow comments in the middle of statements to be on their own line.Daniel Jasper
This fixes llvm.org/PR14860. Before, we messed up the format of: if (DeclaratorInfo.isFunctionDeclarator() && //getDeclSpecContextFromDeclaratorContext(Context) == DSC_top_level && Tok.is(tok::semi) && NextToken().is(tok::l_brace)) { } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171961 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-09Improve formatting of conditional operators.Daniel Jasper
This addresses llvm.org/PR14864. We used to completely mess this up and now format as: Diag(NewFD->getLocation(), getLangOpts().MicrosoftExt ? diag::ext_function_specialization_in_class : diag::err_function_specialization_in_class) << NewFD->getDeclName(); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171957 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-09When name lookup for a redeclaration finds declarations that are knownDouglas Gregor
(because they are part of some module) but have not been made visible (because they are in a submodule that wasn't imported), filter out those declarations unless both the old declaration and the new declaration have external linkage.

Thanks to Dmitri Gribenko for the suggestion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171889 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-08Mark all subsequent decls used.Rafael Espindola
In the source static void f(); static void f(); template<typename T> static void g() { f(); } static void f() { } void h() { g<int>(); } the call to f refers to the second decl, but it is only marked used at the end of the translation unit during instantiation, after the third f decl has been linked in. With this patch we mark all subsequent decls used, so that it is easy to check if a symbol is used or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171888 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-08Don't put spaces around ##.Daniel Jasper
In Clang/LLVM this seems to be the more common formatting for ##s. There might still be case that we miss, but we'll fix those as we go along.

2013-01-08Change the data structure used in clang-format.Daniel Jasper
This is a first step towards supporting more complex structures such as #ifs inside unwrapped lines. This patch mostly converts the array-based UnwrappedLine into a linked-list-based UnwrappedLine. Future changes will allow multiple children for each Token turning the UnwrappedLine into a tree. No functional changes intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171856 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-08[analyzer] Include the bug uniqueing location in the issue_hash.Anna Zaks
The issue here is that if we have 2 leaks reported at the same line for which we cannot print the corresponding region info, they will get treated as the same by issue_hash+description. We need to AUGMENT the issue_hash with the allocation info to differentiate the two issues. Add the "hash" (offset from the beginning of a function) representing allocation site to solve the issue. We might want to generalize solution in the future when we decide to track more than just the 2 locations from the diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171825 91177308-0d34-0410-b5e6-96231b3b80d8

This is in preparation for using this to construct the function type for pointers to member functions to include the implicit/artificial 'this' parameter in that case as well.
