2013-03-05Use ASTContext::getDeclAlign(<Field Decl>) to get the alignment of the firstLang Hames
field to be memcpy'd, rather instead of ASTContext::getTypeAlign(<Field Type>). For packed structs the alignment of a field may be less than the alignment of the field's type. <rdar://problem/13338585> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176512 91177308-0d34-0410-b5e6-96231b3b80d8

[[noreturn]] function are not required to also be [[noreturn]].

2013-03-03Improve C11 atomics support:David Chisnall
- Generate atomicrmw operations in most of the cases when it's sensible to do so. - Don't crash in several common cases (and hopefully don't crash in more of them). - Add some better tests. We now generate significantly better code for things like: _Atomic(int) x; ... x++; On MIPS, this now generates a 4-instruction ll/sc loop, where previously it generated about 30 instructions in two nested loops. On x86-64, we generate a single lock incl, instead of a lock cmpxchgl loop (one instruction instead of ten). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176420 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-28Use the actual ABI-determined C calling convention for runtimeJohn McCall
calls and declarations. LLVM has a default CC determined by the target triple. This is not always the actual default CC for the ABI we've been asked to target, and so we sometimes find ourselves annotating all user functions with an explicit calling convention. Since these calling conventions usually agree for the simple set of argument types passed to most runtime functions, using the LLVM-default CC in principle has no effect. However, the LLVM optimizer goes into histrionics if it sees this kind of formal CC mismatch, since it has no concept of CC compatibility. Therefore, if this module happens to define the "runtime" function, or got LTO'ed with such a definition, we can miscompile; so it's quite important to get this right. Defining runtime functions locally is quite common in embedded applications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176286 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-27Use the correct alignment for POD-member memcpys where the first field is aLang Hames

2013-02-17[CodeGen] tighten objc ivar invariant.load attributionSaleem Abdulrasool
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.
