This patch will optimize the following movq %rdi, %rax subq %rsi, %rax cmovsq %rsi, %rdi movq %rdi, %rax to cmpq %rsi, %rdi cmovsq %rsi, %rdi movq %rdi, %rax Perform this optimization if the actual result of SUB is not used. rdar: 11540023 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157755 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-31X86: Rename the CLMUL target feature to PCLMUL.Benjamin Kramer
It was renamed in gcc/gas a while ago and causes all kinds of confusion because it was named differently in llvm and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157745 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-31Added FMA3 Intel instructions.Elena Demikhovsky
I disabled FMA3 autodetection, since the result may differ from expected for some benchmarks. I added tests for GodeGen and intrinsics. I did not change llvm.fma.f32/64 - it may be done later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157737 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-30it's pointed out that R11 can be used for magic things, and doing things ↵Chris Lattner
just for 64-bit registers is silly. Just optimize 3 more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157699 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-30Extend the (abi-irrelevant) return convention to be able to return more than ↵Chris Lattner
two values in integer registers. This is already supported by the fastcc convention, but it doesn't hurt to support it in the standard conventions as well. In cases where we can cheat at the calling convention, this allows us to avoid returning things through memory in more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157698 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-30Port support for SSE4a extrq/insertq to the old jit code emitter.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157685 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-29Add intrinsics, code gen, assembler and disassembler support for the SSE4a ↵Benjamin Kramer
extrq and insertq instructions. This required light surgery on the assembler and disassembler because the instructions use an uncommon encoding. They are the only two instructions in x86 that use register operands and two immediates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157634 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-18Refactor data-in-code annotations.Jim Grosbach
Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-07Add an MF argument to TRI::getPointerRegClass() and TII::getRegClass().Jakob Stoklund Olesen
The getPointerRegClass() hook can return register classes that depend on the calling convention of the current function (ptr_rc_tailcall). So far, we have been able to infer the calling convention from the subtarget alone, but as we add support for multiple calling conventions per target, that no longer works.
