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.

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

2012-10-26This patch addresses a 64-bit PowerPC ELF ABI compatibility issue withBill Schmidt
varargs parameter passing. A strict reading of the ABI indicates that any argument with alignment greater than 8 may require skipping doublewords in the parameter save area to align the argument, and hence require skipping GPRs. In practice, this is not done by GCC. The alignment restriction is used for internal alignment of a structure, but a structure with 16-byte alignment, for example, is not itself 16-byte aligned in the parameter save area. Although this is messy, it has become the de facto standard used in building existing libraries. My initial varargs support followed the ABI language, but not the de facto standard. Running the GCC compatibility test suite exposed this issue, and indeed showed that LLVM didn't pass parameters self-consistently with my original logic. Removing the additional alignment logic allows the affected tests to now pass. I modified the ppc64-varargs-struct.c test case to remove the existing test for generation of alignment code, which is no longer appropriate. Built and tested on powerpc64-unknown-linux-gnu with no new regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166805 91177308-0d34-0410-b5e6-96231b3b80d8
