2012-06-06Revert r157755.Manman Ren
The commit is intended to fix rdar://11540023. It is implemented as part of peephole optimization. We can actually implement this in the SelectionDAG lowering phase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158122 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-06Remove unused private fields found by clang's new -Wunused-private-field.Benjamin Kramer
There are some that I didn't remove this round because they looked like obvious stubs. There are dead variables in gtest too, they should be fixed upstream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158090 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-01Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen
No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157854 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-01X86: peephole optimization to remove cmp instructionManman Ren
This patch will optimize the following: sub r1, r3 cmp r3, r1 or cmp r1, r3 bge L1 TO sub r1, r3 bge L1 or ble L1 If the branch instruction can use flag from "sub", then we can eliminate the "cmp" instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157831 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-01Implement the local-dynamic TLS model for x86 (PR3985)Hans Wennborg
This implements codegen support for accesses to thread-local variables using the local-dynamic model, and adds a clean-up pass so that the base address for the TLS block can be re-used between local-dynamic access on an execution path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157818 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-01Remove fadd(fmul) patterns for FMA3. This needs to be implemented by paying ↵Craig Topper
attention to FP_CONTRACT and matching @llvm.fma which is not available yet. This will allow us to enablle intrinsic use at least though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157804 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-31X86: Rename the CLMUL target feature to PCLMUL.Benjamin Kramer

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

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

2012-05-29Add 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
