2012-12-30Remove the Function::getFnAttributes method in favor of using the AttributeSetBill Wendling
directly. This is in preparation for removing the use of the 'Attribute' class as a collection of attributes. That will shift to the AttributeSet class instead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171254 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-29Don't warn for undefined but used decls that are external because of a typedef.Rafael Espindola
This fixes pr14736. It is fairly ugly, but I don't think we can do much better as we have to wait at least until the end of the typedef to know if the function will have external linkage or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171240 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-29Try to re-structure the GCCVersion comparison routine to make it easierChandler Carruth
to read and tell that it is a SWO -- we now descend through the components and return a result at the first inequal component. Also comment it a bit better and make it a total ordering by sorting on the text of the suffix if necessary. None of this should really be a visible change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171219 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-28Reject overloading of two static extern C functions.Rafael Espindola
This patch moves hasCLanguageLinkage to be VarDecl and FunctionDecl methods so that they can be used from SemaOverload.cpp and then fixes the logic in Sema::IsOverload. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171193 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-26Fix a regression from the previous commit.Rafael Espindola
Template instantiation can set the canonical decl to used after subsequent decls have been chained, so we have to check that too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171088 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-25Fix for PR12222.Erik Verbruggen
Changed getLocStart() and getLocEnd() to be required for Stmts, and make getSourceRange() optional.

2012-12-25Add 171048 back but invalidate the cache of all redeclarations when settingRafael Espindola
the body of a functions. The problem was that hasBody looks at the entire chain and causes problems to -fvisibility-inlines-hidden if the cache was not invalidated. Original message: Cache visibility of decls. This unifies the linkage and visibility caching. I first implemented this when working on pr13844, but the previous fixes removed the performance advantage of this one. This is still a step in the right direction for making linkage and visibility cheap to use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171053 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-24Let clang-format format itself.Daniel Jasper
Apply all formatting changes that clang-format would apply to its own source code. All choices seem to improve readability (or at least not make it worse). No functional changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171039 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24Penalize tokens with a lower parenthesis level than the start of the line.Daniel Jasper
This prevents formattings like this (assuming "parameter" doesn't fit the line): bool f = someFunction() && someFunctionWithParam( parameter) && someOtherFunction(); Here, "parameter" - the start of line 2 - has a parenthesis level of 2, but there are subsequent tokens ("&&" and "someOtherFunction") with a lower level. This is bad for readability as "parameter" hides "someOtherFunction". With this patch, this changes to: bool f = someFunction() && someFunctionWithParam(parameter) && someOtherFunction(); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171038 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-24Fix formatting over overloaded operators.Daniel Jasper
This fixes llvm.org/pr14686. We used to add too many spaces for different versions of overloaded operator function declarations/definitions.

2012-12-24Take operator precedence into account when splitting lines.Daniel Jasper
With this patch, splitting after binary operators has a panelty corresponding to the operator's precedence. We used to ignore this and eagerly format like: if (aaaaaaaaaaaaaaaaaaaaaaaaa || bbbbbbbbbbbbbbbbbbbbbbbbb && ccccccccccccccccccccccccc) { .. } With this patch, this becomes: if (aaaaaaaaaaaaaaaaaaaaaaaaa || bbbbbbbbbbbbbbbbbbbbbbbbb && ccccccccccccccccccccccccc) { .. } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171007 91177308-0d34-0410-b5e6-96231b3b80d8
