2012-11-06ARM byval: when type alignment is bigger than ABI alignment, instead ofManman Ren
disabling byval, we set realign to true. It will perform an aligned alloca, and call memcpy to copy the byval argument to the local variable. Change the size threshold back to 64 bytes. rdar://12596507 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167440 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-06[PCH] Write out the ClassTemplateDecl::Common::InjectedClassNameType typeArgyrios Kyrtzidis
reference instead of relying on computing it. In general, if storage is no issue, it is preferable to deserialize info from the PCH instead of trying to recompute it after the PCH was loaded. The incentive to change this now was due to r155303 changing how friend template classes in dependent contexts are handled; such classes can now be chained to a previous template class but the computed InjectedClassNameType may be different due to the extra template parameters from the dependent context. The new handling requires more investigation but, in the meantime, writing out InjectedClassNameType fixes PCH issue in rdar://12627738. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167425 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-05Add -fsanitize=<sanitizers> argument to driver and frontend, and addRichard Smith
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the various UBSan checks to be enabled and disabled separately. Right now, the different modes can't be combined, but the intention is that combining UBSan and the other sanitizers will be permitted in the near future. Currently, the UBSan checks will all be enabled if any of them is; that will be fixed by the next patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167411 91177308-0d34-0410-b5e6-96231b3b80d8

While we're here, extend the module map to cover most of the newly-added instrinsic headers. Only wmmintrin.h is missing, because it needs to be split into AES/PCLMUL subheaders (as a separate commit). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167398 91177308-0d34-0410-b5e6-96231b3b80d8

If someone contributes (say) and MD4 implementation, we'd happily switch to that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167397 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-05On PowerPC64, integer arguments and return values need to be sign- orUlrich Weigand
zero-extended to 64 bits. This information is currently provided to the back end by setting "signext" or "zeroext" attributes. However, this is done only for integer types *smaller* than i32, not for i32 itself. This causes clang to generate code violating the ABI, which results in a failure of the tramp3d-v4 test case (due to calling a system library routine without ABI-required extension). This patch implements custom versions of classifyArgumentType and classifyReturnType for PPC64_SVR4_ABIInfo, which are the same as the default versions except that they also classify "int" and "unsigned int" as types needing extending. This fixed tramp3d-v4 on PowerPC64. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167393 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-05[analyzer] Move convenience REGISTER_*_WITH_PROGRAMSTATE to CheckerContext.hJordan Rose
As Anna pointed out, ProgramStateTrait.h is a relatively obscure header, and checker writers may not know to look there to add their own custom state. The base macro that specializes the template remains in ProgramStateTrait.h (REGISTER_TRAIT_WITH_PROGRAMSTATE), which allows the analyzer core to keep using it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167385 91177308-0d34-0410-b5e6-96231b3b80d8
