2010-02-28Implement XMM subregs.Dan Gohman
Extracting the low element of a vector is now done with EXTRACT_SUBREG, and the zero-extension performed by load movss is now modeled with SUBREG_TO_REG, and so on. Register-to-register movss and movsd are no longer considered copies; they are two-address instructions which insert a scalar into a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97354 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-27remove a bogus pattern, which had the same pattern as STDUChris Lattner
but codegen'd differently. This really wanted to use some sort of subreg to get the low 4 bytes of the G8RC register or something. However, it's invalid and nothing is testing it, so I'm just zapping the bogosity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97345 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-26Merge PPC instructions FMRS and FMRD into a single FMR instruction.Jakob Stoklund Olesen
This is possible because F8RC is a subclass of F4RC. We keep FMRSD around so fextend has a pattern. Also allow folding of memory operands on FMRSD. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97275 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Use the right floating point load/store instructions in ↵Jakob Stoklund Olesen
PPCInstrInfo::foldMemoryOperandImpl(). The PowerPC floating point registers can represent both f32 and f64 via the two register classes F4RC and F8RC. F8RC is considered a subclass of F4RC to allow cross-class coalescing. This coalescing only affects whether registers are spilled as f32 or f64. Spill slots must be accessed with load/store instructions corresponding to the class of the spilled register. PPCInstrInfo::foldMemoryOperandImpl was looking at the instruction opcode which is wrong. X86 has similar floating point register classes, but doesn't try to fold memory operands, so there is no problem there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97262 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-26Currently in LLVM, names of libcalls are assigned during TargetLoweringSanjiv Gupta
object construction. There is no provision to change them when the code for a function generated. So we have to change these names while printing assembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97213 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Revert r97064. Duncan pointed out that bitcasts are defined inDan Gohman
terms of store and load, which means bitcasting between scalar integer and vector has endian-specific results, which undermines this whole approach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97137 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Large stack frame patch for the CellSPU: handle stack frames that exceed 8176Scott Michel
(511*16) bytes register displacement (D-form). NOTE: This is a potential headache, given the SPU's local core limitations, allowing the software developer to commit stack overrun suicide unknowingly. Also, large SPU stack frames will cause code size explosion. But, one presumes that the software developer knows what they're doing...
