2012-10-10tblgen: Use semantically correct RTTI functions.Sean Silva
Also, some minor cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165647 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
2012-10-10Add 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

2012-10-09Initial assembler implementation of Mips load address macroJack Carter
This patch provides initial implementation of load address macro instruction for Mips. We have implemented two kinds of expansions with their variations depending on the size of immediate operand: 1) load address with immediate value directly: * la d,j => addiu d,$zero,j (for -32768 <= j <= 65535) * la d,j => lui d,hi16(j) ori d,d,lo16(j) (for any other 32 bit value of j) 2) load load address with register offset value * la d,j(s) => addiu d,s,j (for -32768 <= j <= 65535) * la d,j(s) => lui d,hi16(j) (for any other 32 bit value of j) ori d,d,lo16(j) addu d,d,s This patch does not cover the case when the address is loaded from the value of the label or function.
