* Make sure we apply attributes to correct places.Bill Wendling2013-02-221-13/+17
| | | | | | | Some attributes make sense only on the function or on the call site, but not both. Make this distinction here. llvm-svn: 175918

* [Sema] Semantic analysis for empty-declaration and attribute-declaration.Michael Han2013-02-222-0/+2
| | | | | | | | Introduce a new AST Decl node "EmptyDecl" to model empty-declaration. Have attributes from attribute-declaration appertain to the EmptyDecl node by creating the AST representations of these attributes and attach them to the EmptyDecl node so these attributes can be sema checked just as attributes attached to "normal" declarations. llvm-svn: 175900

| | | | | | | | | | | | | | control the visibility of a type for the purposes of RTTI and template argument restrictions independently of how visibility propagates to its non-type member declarations. Also fix r175326 to not ignore template argument visibility on a template explicit instantiation when a member has an explicit attribute but the instantiation does not.

* Re-apply r174919 - smarter copy/move assignment/construction, with fixes forLang Hames2013-02-173-1/+375
| | | | | | | | | | | bitfield related issues. The original commit broke Takumi's builder. The bug was caused by bitfield sizes being determined by their underlying type, rather than the field info. A similar issue with bitfield alignments showed up on closer testing. Both have been fixed in this patch. llvm-svn: 175389
* [CodeGen] tighten objc ivar invariant.load attributionSaleem Abdulrasool2013-02-171-4/+25
| | | | | | | | | | | | | | | | | An ivar ofset cannot be marked as invariant load in all cases. The ivar offset is a lazily initialised constant, which is dependent on an objc_msgSend invocation to perform a fixup of the offset. If the load is being performed on a method implemented by the class then this load can safely be marked as an inviarant because a message must have been passed to the class at some point, forcing the ivar offset to be resolved. An additional heuristic that can be used to identify an invariant load would be if the ivar offset base is a parameter to an objc method. However, without the parameters available at hand, this is currently not possible.

* When generating IR for default copy-constructors, copy-assignment operators,Lang Hames2013-02-113-1/+364
| | | | | | | | | | | | | | | | | | | | move-constructors and move-assignment operators, use memcpy to copy adjacent POD members. Previously, classes with one or more Non-POD members would fall back on element-wise copies for all members, including POD members. This often generated a lot of IR. Without padding metadata, it wasn't often possible for the LLVM optimizers to turn the element-wise copies into a memcpy. This code hasn't yet received any serious tuning. I didn't see any serious regressions on a self-hosted clang build, or any of the nightly tests, but I think it's important to get this out in the wild to get more testing. Insights, feedback and comments welcome. Many thanks to David Blaikie, Richard Smith, and especially John McCall for their help and feedback on this work. llvm-svn: 174919

* CodeGen: Implement hint values for dynamic_cast as described in the Itanium ↵Benjamin Kramer2013-02-031-2/+59
| | | | | | | | | | | | | | | C++ ABI. This can yield dramatic speedups of dynamic_cast for simple inheritance trees, at least with libsupc++. Neither libcxxabi nor libcxxrt make use of this hint currently, it was never implemented because clang didn't support it. There was some concern about the number of class hierarchy walks this change introduces. If it turns out to be an issue we can add caching either at the cast pair level or even deeper, but we also do a lot of walks in Sema so this codepath is probably fairly optimized already. llvm-svn: 174293
