2013-01-07[analyzer] Fix a false positive in the ivar invalidation checker.Anna Zaks
When a property is "inherited" through both a parent class and directly through a protocol, we should not require the child to invalidate it since the backing ivar belongs to the parent class.

2013-01-07Fix parsing of variable declarations directly after a class / struct.Manuel Klimek
Previous indent: class A { } a; void f() { }; With this patch: class A { } a; void f() { } ; The patch introduces a production for classes and structs, and parses the rest of the line to the semicolon after the class scope. This allowed us to remove a long-standing wart in the parser that would just much the semicolon after any block. Due to this suboptimal formating some tests were broken. Some unrelated formatting tests broke; those hit a bug in the ast printing, and need to be fixed separately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171761 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Add fixit hints for misplaced C++11 attributes around class specifiers.Michael Han
Following r168626, in class declaration or definition, there are a combination of syntactic locations where C++11 attributes could appear, and among those the only valid location permitted by standard is between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to move them to expected location and we recover by applying them to the class specifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171757 91177308-0d34-0410-b5e6-96231b3b80d8

with respect to the lower "left-hand-side bitwidth" bits, even when negative); see OpenCL spec 6.3j. This patch both implements this behaviour in the code generator and "constant folding" bits of Sema, and also prevents tests to detect undefinedness in terms of the weaker C99 or C++ specifications from being applied. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171755 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Prefer not to break after assignments.Daniel Jasper
This addresses llvm.org/PR14830. Before: unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(), SI->getPointerAddressSpace()); CharSourceRange LineRange = CharSourceRange::getTokenRange(TheLine.Tokens.front().Tok.getLocation(), TheLine.Tokens.back().Tok.getLocation()); After: unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(), SI->getPointerAddressSpace()); CharSourceRange LineRange = CharSourceRange::getTokenRange( TheLine.Tokens.front().Tok.getLocation(), TheLine.Tokens.back().Tok.getLocation()); This required rudimentary changes to static initializer lists, but we are not yet formatting them in a reasonable way. That will be done in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171731 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07Add style option for number of spaces before trailing comments.Daniel Jasper
In LLVM style, a single space should be enough. In Google style, two spaces are required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171725 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07Do not break before "0" in pure virtual function declarations.Daniel Jasper
Before: virtual void write(ELFWriter *writer, OwningPtr<FileOutputBuffer> &buffer) = 0 After: virtual void write(ELFWriter *writerrr, OwningPtr<FileOutputBuffer> &buffer) = 0; This addresses llvm.org/PR14815. To implement this I introduced a line type during parsing and moved the definition of TokenType out of the struct for increased readability. Should have done the latter in a separate patch, but it would be hard to pull apart now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171724 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07Fix incorrect FIXME.Manuel Klimek
The case that we wanted to write a test for cannot happen, as the UnwrappedLineParser already protects against it. Added an assert to prevent regressions of that assumption. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171720 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Do not ever allow using the full line in preprocessor directives.Manuel Klimek
We would format: #define A \ int f(a); int i; as #define A \ int f(a);\ int i The fix will break up macro definitions that could fit a line, but hit the last column; fixing that is more involved, though, as it requires looking at the following line. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171715 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07Fix layouting of single-line-comments preceded by an escaped newline.Manuel Klimek
Previously, we'd format int i;\ // comment as int i; // comment The problem is that the escaped newline is part of the next token, and thus the raw token text of the comment doesn't start with "//". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171713 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07Fix layouting of tokens with a leading escaped newline.Manuel Klimek
If a token follows directly on an escaped newline, the escaped newline is stored with the token. Since we re-layout escaped newlines, we need to treat them just like normal whitespace - thus, we need to increase the whitespace-length of the token, while decreasing the token length (otherwise the token length contains the length of the escaped newline and we double-count it while indenting). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171706 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-06Fixes handling of unbalances braces.Manuel Klimek
If we find an unexpected closing brace, we must not stop parsing, as we'd otherwise not layout anything beyond that point. If we find a structural error on the highest level we'll not re-indent anyway, but we'll still want to format within unwrapped lines. Needed to introduce a differentiation between an expected and unexpected closing brace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171666 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-05Fixes parsing of hash tokens in the middle of a line.Manuel Klimek
To parse # correctly, we need to know whether it is the first token in a line - we can deduct this either from the whitespace or seeing that the token is the first in the file - we already calculate this information. This patch moves the identification of the first token into the getNextToken method and stores it inside the FormatToken, so the UnwrappedLineParser can stay independent of the SourceManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171640 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-04Various fixes to clang-format's macro handling.Manuel Klimek
Some of this is still pretty rough (note the load of FIXMEs), but it is strictly an improvement and fixes various bugs that were related to macro processing but are also imporant in non-macro use cases. Specific fixes: - correctly puts espaced newlines at the end of the line - fixes counting of white space before a token when escaped newlines are present - fixes parsing of "trailing" tokens when eof() is hit - puts macro parsing orthogonal to parsing other structure - general support for parsing of macro definitions Due to the fix to format trailing tokens, this change also includes a bunch of fixes to the c-index tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171556 91177308-0d34-0410-b5e6-96231b3b80d8
