* This patch solves a problem with passing varargs parameters under the PPC64Bill Schmidt2012-10-292-1/+34
| | | | | | | | | | | | | | | | | | | ELF ABI. A varargs parameter consisting of a single-precision floating-point value, or of a single-element aggregate containing a single-precision floating-point value, must be passed in the low-order (rightmost) four bytes of the doubleword stack slot reserved for that parameter. If there are GPR protocol registers remaining, the parameter must also be mirrored in the low-order four bytes of the reserved GPR. Prior to this patch, such parameters were being passed in the high-order four bytes of the stack slot and the mirrored GPR. The patch adds a new test case to verify the correct code generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166968 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch adds alignment information for long double to the 64-bit PowerPCBill Schmidt2012-10-292-0/+32
| | | | | | | | | | | | | | | | | | ELF subtarget. The existing logic is used as a fallback to avoid any changes to the Darwin ABI. PPC64 ELF now has two possible data layout strings: one for FreeBSD, which requires 8-byte alignment, and a default string that requires 16-byte alignment. I've added a test for PPC64 Linux to verify the 16-byte alignment. If somebody wants to add a separate test for FreeBSD, that would be great. Note that there is a companion patch to update the alignment information in Clang, which I am committing now as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166928 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch is for the implementation of mips16 complex pattern addr16.Reed Kotler2012-10-289-48/+409
| | | | | | | | | | | | | | | | | | | | | | | Previously mips16 was sharing the pattern addr which is used for mips32 and mips64. This had a number of problems: 1) Storing and loading byte and halfword quantities for mips16 has particular problems due to the primarily non mips16 nature of SP. When we must load/store byte/halfword stack objects in a function, we must create a mips16 alias register for SP. This functionality is tested in stchar.ll. 2) We need to have an FP register under certain conditions (such as dynamically sized alloca). We use mips16 register S0 for this purpose. In this case, we also use this register when accessing frame objects so this issue also affects the complex pattern addr16. This functionality is tested in alloca16.ll. The Mips16InstrInfo.td has been updated to use addr16 instead of addr. The complex pattern C++ function for addr has been copied to addr16 and updated to reflect the above issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166897 91177308-0d34-0410-b5e6-96231b3b80d8
