2012-10-09Initialize the end loc in ObjCInterfaceTypeLoc.Benjamin Kramer
Found by valgrind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165546 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-09The clang driver has a fairly fancy support for executing gcc instead ofRafael Espindola
clang itself. This dates back to clang's early days and while it looks like some of it is still used (for kext for example), other parts are probably dead. Remove the -ccc-clang-archs option and associated code. I don't think there is any remaining setup where clang doesn't support an architecture but it can expect an working gcc cross compiler to be available. A nice side effect is that tests no longer need to differentiate architectures that are included in production builds of clang and those that are not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165545 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-09When we load a function or method body from an AST file, we checkDouglas Gregor

2012-10-09If a macro has been #undef'd in a precompiled header, we still need toDouglas Gregor
write out the macro history for that macro. Similarly, we need to cope with reading a macro definition that has been #undef'd. Take advantage of this new ability so that global code-completion results can refer to #undef'd macros, rather than losing them entirely. For multiply defined/#undef'd macros, we will still get the wrong result, but it's better than getting no result. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165502 91177308-0d34-0410-b5e6-96231b3b80d8

The darwin change should be a nop since Triple::getArchTypeForDarwinArchName doesn't know about amd64.

This should fix the bots. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165358 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-06ParentMap: Restore the ability to update an existing map.Jordan Rose
The Clang ASTs are a DAG, not a pure tree. However, ParentMap has to choose a single parent for each object. In the main (only?) cases in which the AST forms a DAG, it protects from multiple traversal by using OpaqueValueExprs. Previously, ParentMap would just unconditionally look through all OpaqueValueExprs when building its map. In order to make this behavior better for the analyzer's diagnostics, ParentMap was changed to not set a statement's parent if there already was one in the map. However, ParentMap is supposed to allow updating existing mappings by calling addStmt once again. This change makes the "transparency" of OpaqueValueExprs explicit, and disables it when it is not desired, rather than checking the current contents of the map. This new code seems like a big change, but it should actually have essentially the same performance as before. Only OpaqueValueExprs and their users (PseudoObjectExpr and BinaryConditionalOperator) will have any different behavior. There should be no user-visible functionality change, though a test has been added for the current behavior of BinaryConditionalOperator source locations and accompanying Xcode arrows (which are not so great...). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165355 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-06[analyzer] Handle implicit statements used for end-of-path nodes' source locs.Jordan Rose
