2012-04-20[libclang] Don't set dylib load address to 0xe000000.Argyrios Kyrtzidis
Per Greg Clayton: libclang.dylib is trying to be smart and load itself at a valid address to be able to load faster which would work for 32 bit systems, bit won't make any difference on 64 bit systems. It should either pick a better 64 bit address, or just let itself be loaded at zero. rdar://11159142 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155246 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-20[analyzer] Run remove dead bindings right before leaving a function.Anna Zaks
This is needed to ensure that we always report issues in the correct function. For example, leaks are identified when we call remove dead bindings. In order to make sure we report a callee's leak in the callee, we have to run the operation in the callee's context. This change required quite a bit of infrastructure work since: - We used to only run remove dead bindings before a given statement; here we need to run it after the last statement in the function. For this, we added additional Program Point and special mode in the SymbolReaper to remove all symbols in context lower than the current one. - The call exit operation turned into a sequence of nodes, which are now guarded by CallExitBegin and CallExitEnd nodes for clarity and convenience. (Sorry for the long diff.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155244 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19In Parser::isCXXDeclarationSpecifier, consider a non-type identifierKaelyn Uhrain
followed by an identifier as declaration specificer (except for ObjC). This allows e.g. an out-of-line C++ member function definitions to be recognized as functions and not as variable declarations if the type name for the first parameter is not recognized as a type--say, when there is a function name shadowing an enum type name and the parameter is missing the "enum" keyword needed to distinguish the two. Note that returning TPResult::Error() instead of TPResult::True() appears to have the same end result, while TPResult::Ambiguous() results in a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155163 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19In mergeVisibility, if we already have an explicit visibility, keep it.Rafael Espindola
This fixes the included testcase and lets us simplify the code a bit. It does require using mergeWithMin when merging class information to its members. Expand the comments to explain why that works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155103 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19In mergeVisibilityWithMin, let an implicit hidden symbol take precedence overRafael Espindola
an explicit default one. This means that with -fvisibility hidden we now produce a hidden symbol for template <typename T> class DEFAULT foo { void bar() {} }; class zed {}; template class foo<zed>; This matches the behaviour of gcc 4.7. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155102 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19Now that we check visibility attributes in an appropriate order,Rafael Espindola
there is no need for mergeVisibily to ever increase the visibility. Not doing so lets us replace an incorrect use of mergeVisibilityWithMin. The testcase struct HIDDEN RECT { int top; }; DEFAULT RECT foo = {0}; shows that we should give preference to one of the attributes instead of keeping the minimum. We still get this testcase wrong because mergeVisibily handles two explicit visibilities incorrectly, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155101 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19Move the point in the code where we handle -fvisibility=hidden. WithRafael Espindola
the current implementation this should be a nop as explicit visibility takes precedence in mergeVisibility. The location chosen is such that attributes checked above it can force a symbol to be default. For example, an attribute is the variable or function. Attributes checked after this point, can only make the visibility more restrictive. An attribute in a type for example. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155098 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19Make setVisibility private and change users to mergeVisibility. This isRafael Espindola
currently a nop as those users are the first merge or are a merge of a hidden explicit visibility, which always wins in the current implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155095 91177308-0d34-0410-b5e6-96231b3b80d8
