2013-01-03Warn on unused auto variables.Rafael Espindola
To do so we have to wait until we know that the type of a variable has been deduced. Sema::FinalizeDeclaration is the first callback that is used for decl with or without initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171458 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
2012-12-28Reject 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

2012-12-28Change this to an IR test instead of an assembly test (as per comment in ↵David Blaikie
r171134). This makes the test not dependent on LLVM & won't vary/break based on LLVM codegen related changes. Appropriately testing at the Clang level what was fixed at the Clang level originally (in r124210). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171175 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

2012-12-25Add 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

2012-12-24test/Index/preamble_macro_template.cpp: Tweak for win32.NAKAMURA Takumi
Using the file immediately after "> file 2>&1" causes weird behavior on win32. For example, "foo > %t 2>&1; FileCheck --input-file=%t" Use "foo 2>&1 | tee %t" instead. Note, mixing stdout and stderr to the same handle might cause unexpected behavior, due to buffering. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171009 91177308-0d34-0410-b5e6-96231b3b80d8

Along the way, fix a bug in CheckLiteralKind(), previously in diagnoseObjCLiteralComparison, where we didn't ignore parentheses in boxed expressions for purpose of classification.

2012-12-21[analyzer] Re-apply r170826 and make the dumping of the GallGraphAnna Zaks
deterministic. Commit message for r170826: [analyzer] Traverse the Call Graph in topological order. Modify the call graph by removing the parentless nodes. Instead all nodes are children of root to ensure they are all reachable. Remove the tracking of nodes that are "top level" or global. This information is not used and can be obtained from the Decls stored inside CallGraphNodes. Instead of existing ordering hacks, analyze the functions in topological order over the Call Graph. Together with the addition of devirtualizable ObjC message sends and blocks to the call graph, this gives around 6% performance improvement on several large ObjC benchmarks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170906 91177308-0d34-0410-b5e6-96231b3b80d8
