2012-10-10Move Sema::PropertyIfSetterOrGetter to ObjCMethodDecl::findPropertyDecl.Jordan Rose
Then, switch users of PropertyIfSetterOrGetter and LookupPropertyDecl (the latter by name) over to findPropertyDecl. This actually makes -Wreceiver-is-weak a bit stronger than it was before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165628 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Change Sema::PropertyIfSetterOrGetter to make use of isPropertyAccessor.Jordan Rose
Old algorithm: 1. See if the name looks like a getter or setter. 2. Use the name to look up a property in the current ObjCContainer and all its protocols. 3. If the current container is an interface, also look in all categories and superclasses (and superclass categories, and so on). New algorithm: 1. See if the method is marked as a property accessor. If so, look through all properties in the current container and find one that has a matching selector. 2. Find all overrides of the method using ObjCMethodDecl's getOverriddenMethods. This collects methods in superclasses and protocols (as well as superclass categories, which isn't really necessary), and checks if THEY are accessors. This part is not done recursively, since getOverriddenMethods is already recursive. This lets us handle getters and setters that do not match the property names. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165627 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.Jordan Rose
This more accurately reflects its use: this flag is set when a method matches the getter or setter name for a property in the same class, and does not actually specify whether or not the definition of the method will be synthesized (either implicitly or explicitly with @synthesize). This renames the setter and backing field as well, and changes the (soon-to-be-obsolete?) XML dump format to use 'property_accessor' instead of 'synthesized'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165626 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10Apply the same fundamental fix for PR14048 as was applied for PR11905.Chandler Carruth
The issue arises when coercing to/from types of different sizes. We need to be certain that the allocation on either end has sufficient room for the coerced type. When it doesn't, we need to make room, copy across, and then proceed. PR11905 handled the case of storing function arguments back into allocas in the function prolog, this patch handles the case of setting up the function arguments in a call expression. This is actually significantly simpler than the fix for PR11905. It ends up being a trivial change to create a temporary alloca when the source is too small and memcpy across. This should preserve the compile-time fast-isel benefits of doing gep+load sequences and avoiding FCAs.

2012-10-09Rework the (de-)serialization of macros, as stored inDouglas Gregor
MacroInfo*. Instead of simply dumping an offset into the current file, give each macro definition a proper ID with all of the standard modules-remapping facilities. Additionally, when a macro is modified in a subsequent AST file (e.g., #undef'ing a macro loaded from another module or from a precompiled header), provide a macro update record rather than rewriting the entire macro definition. This gives us greater consistency with the way we handle declarations, and ties together macro definitions much more cleanly. Note that we're still not actually deserializing macro history (we never were), but it's far easy to do properly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165560 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

2012-10-06ParentMap: 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
