* R600: Remove AMDIL instruction and register definitionsTom Stellard2014-06-13
| | | | | | Most of these are no longer used any more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210915 91177308-0d34-0410-b5e6-96231b3b80d8

* R600/SI: Only create one instruction when spilling/restoring register v3Tom Stellard2014-05-02
| | | | | | | | | | | | | | | | | | The register spiller assumes that only one new instruction is created when spilling and restoring registers, so we need to emit pseudo instructions for vector register spills and lower them after register allocation. v2: - Fix calculation of lane index - Extend VGPR liveness to end of program. v3: - Use SIMM16 field of S_NOP to specify multiple NOPs. https://bugs.freedesktop.org/show_bug.cgi?id=75005 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207843 91177308-0d34-0410-b5e6-96231b3b80d8

* R600/SI: Return the correct index for VGPRs in getHWRegIndex()Tom Stellard2014-03-31
| | | | | | The register index is stored in the low 8-bits of the encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205186 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix known typosAlp Toker2014-01-24
| | | | | | | Sweep the codebase for common typos. Includes some changes to visible function names that were misspelt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200018 91177308-0d34-0410-b5e6-96231b3b80d8
* R600/SI: Fix moveToVALU when the first operand is VSrc.Matt Arsenault2013-11-18
| | | | | | | Moving into a VSrc doesn't always work, since it could be replaced with an SGPR later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195042 91177308-0d34-0410-b5e6-96231b3b80d8

* R600/SI: Add support for private address space load/storeTom Stellard2013-11-13
| | | | | | | Private address space is emulated using the register file with MOVRELS and MOVRELD instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194626 91177308-0d34-0410-b5e6-96231b3b80d8
* R600/SI: Prefer SALU instructions for bit shift operationsTom Stellard2013-11-13
| | | | | | | | | | | | | | All shift operations will be selected as SALU instructions and then if necessary lowered to VALU instructions in the SIFixSGPRCopies pass. This allows us to do more operations on the SALU which will improve performance and is also required for implementing private memory using indirect addressing, since the private memory pointers must stay in the scalar registers. This patch includes some fixes from Matt Arsenault. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194625 91177308-0d34-0410-b5e6-96231b3b80d8

* R600/SI: Mark the EXEC register as reservedTom Stellard2013-10-10

* R600/SI: Choose the correct MOV instruction for copying immediatesTom Stellard2013-08-14
| | | | | | | | The instruction selector will now try to infer the destination register so it can decided whether to use V_MOV_B32 or S_MOV_B32 when copying immediates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188426 91177308-0d34-0410-b5e6-96231b3b80d8
