2012-11-28objective-C blocks: Make sure that identical logic is usedFariborz Jahanian
in deciding a copy/dispose field is needed in a byref structure and when generating the copy/dispose helpers. In certain cases, these fields were being added but no copy/dispose was being generated. This was uncovered in ARC, but not in MRR. // rdar://12759433 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168825 91177308-0d34-0410-b5e6-96231b3b80d8

the original parameter or return type. Since we do not accurately represent the data fields of a union, we should not directly load or store a union type. As an exmple, if we have i8,i8, i32, i32 as one field type and i32,i32 as another field type, the first field type will be chosen to represent the union. If we load with the union's type, the 3rd byte and the 4th byte will be skipped. rdar://12723368 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168820 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-27objective-C arc: load of a __weak object happens via call toFariborz Jahanian
objc_loadWeak. This retains and autorelease the weakly-refereced object. This hidden autorelease sometimes makes __weak variable alive even after the weak reference is erased, because the object is still referenced by an autorelease pool. This patch overcomes this behavior by loading a weak object via call to objc_loadWeakRetained(), followng it by objc_release at appropriate place, thereby removing the hidden autorelease. // rdar://10849570 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168740 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-27This patch addresses an incompatibility relative to the 64-bit PowerPCBill Schmidt
ELF ABI. Complex values are to be passed in registers as though the real and imaginary parts were passed as separate parameters. Prior to this patch, complex values were passed as byval aggregates. It turns out that specifying getDirect() for all complex types when classifying the argument type results in the desired behavior.

2012-11-21Fix the '-fuse-init-array' option to actually be an option.Chandler Carruth
Previously, this flag to CC1 was never exposed at the clang driver layer, and if you happened to enable it (by being on Android or GCC 4.7 platform), you couldn't *disable* it, because there was no 'no' variant. The whole thing was confusingly implemented. Now, the target-specific flag processing gets the driver arg list, and we use standard hasFlag with a default based on the GCC version and/or Android platform. The user can still pass the 'no-' variant to forcibly disable the flag, or pass the positive variant to clang itself to enable the flag. The test has also been substantially cleaned up and extended to cover these use cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168473 91177308-0d34-0410-b5e6-96231b3b80d8
