2012-10-10Patch by Shuxin Yang <shuxin.llvm@gmail.com>.Nadav Rotem
Original message: The attached is the fix to radar://11663049. The optimization can be outlined by following rules: (select (x != c), e, c) -> select (x != c), e, x), (select (x == c), c, e) -> select (x == c), x, e) where the <c> is an integer constant. The reason for this change is that : on x86, conditional-move-from-constant needs two instructions; however, conditional-move-from-register need only one instruction. While the LowerSELECT() sounds to be the most convenient place for this optimization, it turns out to be a bad place. The reason is that by replacing the constant <c> with a symbolic value, it obscure some instruction-combining opportunities which would otherwise be very easy to spot. For that reason, I have to postpone the change to last instruction-combining phase. The change passes the test of "make check-all -C <build-root/test" and "make -C project/test-suite/SingleSource". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165661 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10When generating spill and reload code for vector registers on PowerPC,Bill Schmidt
the compiler makes use of GPR0. However, there are two flavors of GPR0 defined by the target: the 32-bit GPR0 (R0) and the 64-bit GPR0 (X0). The spill/reload code makes use of R0 regardless of whether we are generating 32- or 64-bit code. This patch corrects the problem in the obvious manner, using X0 and ADDI8 for 64-bit and R0 and ADDI for 32-bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165658 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10The PowerPC VRSAVE register has been somewhat of an odd beast sinceBill Schmidt
the Altivec extensions were introduced. Its use is optional, and allows the compiler to communicate to the operating system which vector registers should be saved and restored during a context switch. In practice, this information is ignored by the various operating systems using the SVR4 ABI; the kernel saves and restores the entire register state. Setting the VRSAVE register is no longer performed by the AIX XL compilers, the IBM i compilers, or by GCC on Power Linux systems. It seems best to avoid this logic within LLVM as well. This patch avoids generating code to update and restore VRSAVE for the PowerPC SVR4 ABIs (32- and 64-bit). The code remains in place for the Darwin ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165656 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Add in support for expansion of all of the comparison operations to the ↵Micah Villmow
absolute minimum required set. This allows a backend to expand any arbitrary set of comparisons as long as a minimum set is supported. The minimum set of required instructions is ISD::AND, ISD::OR, ISD::SETO(or ISD::SETOEQ) and ISD::SETUO(or ISD::SETUNE). Everything is expanded into one of two patterns: Pattern 1: (LHS CC1 RHS) Opc (LHS CC2 RHS) Pattern 2: (LHS CC1 LHS) Opc (RHS CC2 RHS) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165655 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10tblgen: Mechanically move dynamic_cast<> to dyn_cast<>.Sean Silva
Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>. That will happen in a future patch. There are also two dyn_cast_or_null<>'s slipped in instead of dyn_cast<>'s, since they were causing crashes with just dyn_cast<>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165646 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10docs: Propagate fix from r165632 to other docs.Sean Silva
There are only two other instances of using `.. code::` instead of `.. code-block::`. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165633 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10docs: Attempt to fix PR14053.Sean Silva
Hypothesis 1: use of `.. code::` directive instead of `.. code-block::` is causing Sphinx to discard the block. On my machine, `.. code::` renders fine. However, I don't think that `.. code::` is actually a legit Sphinx directive. I believe that on my machine Sphinx is falling back to just displaying it monospace with no syntax, whereas llvm.org's Sphinx is just discarding it. This is truly "remote debugging" since I can't reproduce this on my machine. It would be helpful to be able to see the llvm.org Sphinx build logs; if that's possible please let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165632 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Add support for FP_ROUND from v2f64 to v2f32Michael Liao
- Due to the current matching vector elements constraints in ISD::FP_ROUND, rounding from v2f64 to v4f32 (after legalization from v2f32) is scalarized. Add a customized v2f32 widening to convert it into a target-specific X86ISD::VFPROUND to work around this constraints. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165631 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Add alternative support for FP_ROUND from v2f32 to v2f64Michael Liao
- Due to the current matching vector elements constraints in ISD::FP_EXTEND, rounding from v2f32 to v2f64 is scalarized. Add a customized v2f32 widening to convert it into a target-specific X86ISD::VFPEXT to work around this constraints. This patch also reverts a previous attempt to fix this issue by recovering the scalarized ISD::FP_EXTEND pattern and thus significantly reduces the overhead of supporting non-power-2 vector FP extend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165625 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10Fix for LDRB instruction:Stepan Dyatkovskiy
SDNode for LDRB_POST_IMM is invalid: number of registers added to SDNode fewer that described in .td. 7 ops is needed, but SDNode with only 6 is created. In more details: In ARMInstrInfo.td, in multiclass AI2_ldridx, in definition _POST_IMM, offset operand is defined as am2offset_imm. am2offset_imm is complex parameter type, and actually it consists from dummy register and imm itself. As I understood trick with dummy reg was made for AsmParser. In ARMISelLowering.cpp, this dummy register was not added to SDNode, and it cause crash in Peephole Optimizer pass. The problem fixed by setting up additional dummy reg when emitting LDRB_POST_IMM instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165617 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Issue description:Stepan Dyatkovskiy
SchedulerDAGInstrs::buildSchedGraph ignores dependencies between FixedStack objects and byval parameters. So loading byval parameters from stack may be inserted *before* it will be stored, since these operations are treated as independent. Fix: Currently ARMTargetLowering::LowerFormalArguments saves byval registers with FixedStack MachinePointerInfo. To fix the problem we need to store byval registers with MachinePointerInfo referenced to first the "byval" parameter. Also commit adds two new fields to the InputArg structure: Function's argument index and InputArg's part offset in bytes relative to the start position of Function's argument. E.g.: If function's argument is 128 bit width and it was splitted onto 32 bit regs, then we got 4 InputArg structs with same arg index, but different offset values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165616 91177308-0d34-0410-b5e6-96231b3b80d8
