2013-01-16Fix parsing error in conditional expressions.Daniel Jasper
We used to incorrectly parse aaaaaa ? aaaaaa(aaaaaa) : aaaaaaaa; Due to an l_paren being followed by a colon, we assumed it to be part of a constructor initializer. Thus, we never found the colon belonging to the conditional expression, marked the line as bing incorrect and did not format it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172621 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-16[PCH/Modules] Change how macro [re]definitions are de/serialized.Argyrios Kyrtzidis
Previously we would serialize the macro redefinitions as a list, part of the identifier, and try to chain them together across modules individually without having the info that they were already chained at definition time. Change this by serializing the macro redefinition chain and then try to synthesize the chain parts across modules. This allows us to correctly pinpoint when 2 different definitions are ambiguous because they came from unrelated modules. Fixes bogus "ambiguous expansion of macro" warning when a macro in a PCH is redefined without undef'ing it first. rdar://13016031 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172620 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16Disable inlining of short ifs in Google style.Daniel Jasper
Various reasons seem to speak against it, so I am disabling this for now. Changed tests to still test this option. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172618 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-16Add option to avoid "bin-packing" of parameters.Daniel Jasper
"Bin-packing" here means allowing multiple parameters on one line, if a function call/declaration is spread over multiple lines. This is required by the Chromium style guide and probably desired for the Google style guide. Not making changes to LLVM style as I don't have enough data. With this enabled, we format stuff like: aaaaaaaaaaaaaaa(aaaaaaaaaa, aaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaa).aaaaaaaaaaaaaaaaaa(); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172617 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16Calculate the total length of a line up to each token up front.Daniel Jasper
This makes the tedious fitsIntoLimit() method unnecessary and I can replace one hack (constructor initializers) by a slightly better hack. Furthermore, this will enable calculating whether a certain part of a line fits into the limit for future modifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172604 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-16Change the datastructure for UnwrappedLines.Daniel Jasper
It was quite convoluted leading to us accidentally introducing O(N^2) complexity while copying from UnwrappedLine to AnnotatedLine. We might still want to improve the datastructure in AnnotatedLine (most importantly not put them in a vector where they need to be copied on vector resizing but that will be done as a follow-up. This fixes most of the regression in llvm.org/PR14959. No formatting changes intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172602 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-15Do not traverse the break-state when we know we cannot break anyway.Manuel Klimek
This is an optimization that djasper spottet. For now, we do not format anything after the first token that belongs to such an implicit string literal. All our state is not made for handling that anyway, so we'll revisit this if we find a problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172537 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Fix formatting of preprocessor directives (incluces, warnings & errors).Manuel Klimek
Treat tokens inside <> for includes and everything from the second token of a warning / error on as an implicit string literal, e.g. do not change its whitespace at all. Now correctly formats: #include < path with space > #error Leave all white!!!!! space* alone! Note that for #error and #warning we still format the space up to the first token of the text, so: # error Text will become #error Text git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172536 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-15Fixes various bugs around the keywords class, struct and union.Manuel Klimek
This switches to parsing record definitions only if we can clearly identify them. We're specifically allowing common patterns for visibility control through macros and attributes, but we cannot currently fix all instances. This fixes all known bugs we have though.

with function definitions. We really should remove Parser::isDeclarationAfterDeclarator entirely, since it's meaningless in C++11 (an open brace could be either a function definition or an initializer, which is what it's trying to differentiate between).

2013-01-15Fix behavior of [[gnu::]] function attributes. Per g++'s behavior, theseRichard Smith
attributes appertain to a declaration, even though they would be much more naturally modelled as appertaining to a function type. Previously, we would try to distribute them from the declarator to the function type, then reject them for being at an incorrect location. Now, we just distribute them as far as the declarator; the existing attribute handling code can actually apply them there just fine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172504 91177308-0d34-0410-b5e6-96231b3b80d8
