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

combination of a load+objc_release; this is generally better for tools that try to track why values are retained and released.

2012-10-16Add pnaclcall convention to Native Client targets.Derek Schuff
Because PNaCl bitcode must be target-independent, it uses some different bitcode representations from other targets (e.g. byval and sret for structures). This means that without additional type information, it cannot meet some native ABI requirements for some targets (e.g. passing structures containing unions by value on x86-64). To allow generation of code which uses the correct native ABIs, we also support triples such as x86_64-nacl, which uses target-dependent IR (as opposed to le32-nacl, which uses byval and sret). To allow interoperation between the two types of code, this patch adds a calling convention attribute to be used in code compiled with the target-dependent triple, which will generate code using the le32-style bitcode. This calling convention does not need to be explicitly supported in the backend because it determines bitcode representation rather than native conventions (the backend just needs to undersand how to handle byval and sret for the Native Client OS). This patch implements __attribute__((pnaclcall)) to generate calls in bitcode according to the le32 bitcode conventions, an attribute which is accepted by any Native Client target, but issues a warning otherwise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166065 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-16ARM ABI: passing illegal vector types as varargs.Manman Ren
We expand varargs in clang and the call site is handled in the back end, it is hard to match exactly how illegal vectors are handled in the backend. Therefore, we legalize the illegal vector types in clang: if (Size <= 32), legalize to i32. if (Size == 64), legalize to v2i32. if (Size == 128), legalize to v4i32. if (Size > 128), use indirect. rdar://12439123 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166043 91177308-0d34-0410-b5e6-96231b3b80d8
