* Remove many calls to TII::isMoveInstr. Targets should be producing COPY anyway.Jakob Stoklund Olesen2010-07-161-1/+1
| | | | | | TII::isMoveInstr is going tobe completely removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108507 91177308-0d34-0410-b5e6-96231b3b80d8
* Mark the SPU 'lr' instruction to never have side effects. Kalle Raiskila2010-06-211-2/+2
| | | | | | | | | | This allows the fast regiser allocator to remove redundant register moves. Update a set of tests that depend on the register allocator to be linear scan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106420 91177308-0d34-0410-b5e6-96231b3b80d8

* - Remove Tilmann's custom truncate lowering: it completely hosed overScott Michel2008-12-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | DAGcombine's ability to find reasons to remove truncates when they were not needed. Consequently, the CellSPU backend would produce correct, but _really slow and horrible_, code. Replaced with instruction sequences that do the equivalent truncation in SPUInstrInfo.td. - Re-examine how unaligned loads and stores work. Generated unaligned load code has been tested on the CellSPU hardware; see the i32operations.c and i64operations.c in CodeGen/CellSPU/useful-harnesses. (While they may be toy test code, it does prove that some real world code does compile correctly.) - Fix truncating stores in bug 3193 (note: unpack_df.ll will still make llc fault because i64 ult is not yet implemented.) - Added i64 eq and neq for setcc and select/setcc; started new instruction information file for them in SPU64InstrInfo.td. Additional i64 operations should be added to this file and not to SPUInstrInfo.td. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61447 91177308-0d34-0410-b5e6-96231b3b80d8
* CellSPU:Scott Michel2008-12-091-1/+1
| | | | | | | | - Fix call.ll and call_indirect.ll expected results, now that it's using a different pre-register allocation scheduler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60741 91177308-0d34-0410-b5e6-96231b3b80d8

* - Expand tabs to spaces.Scott Michel2008-03-051-17/+17
| | | | | | | | | - select_bits.ll now fully functional now that PR1993 is closed. It was previously broken by refactoring in SPUInstrInfo.td and using multiclasses. - Same for eqv.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47972 91177308-0d34-0410-b5e6-96231b3b80d8
* Overhaul Cell SPU's addressing mode internals so that there are nowScott Michel2008-01-291-8/+7
| | | | | | | | | | | | | | | only two addressing mode nodes, SPUaform and SPUindirect (vice the three previous ones, SPUaform, SPUdform and SPUxform). This improves code somewhat because we now avoid using reg+reg addressing when it can be avoided. It also simplifies the address selection logic, which was the main point for doing this. Also, for various global variables that would be loaded using SPU's A-form addressing, prefer D-form offs[reg] addressing, keeping the base in a register if the variable is used more than once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46483 91177308-0d34-0410-b5e6-96231b3b80d8

* Forward progress: crtbegin.c now compiles successfully!Scott Michel2008-01-171-8/+18
| | | | | | | | | | | | | | Fixed CellSPU's A-form (local store) address mode, so that all globals, externals, constant pool and jump table symbols are now wrapped within a SPUISD::AFormAddr pseudo-instruction. This now identifies all local store memory addresses, although it requires a bit of legerdemain during instruction selection to properly select loads to and stores from local store, properly generating "LQA" instructions. Also added mul_ops.ll test harness for exercising integer multiplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46142 91177308-0d34-0410-b5e6-96231b3b80d8
* More CellSPU refinements:Scott Michel2008-01-111-0/+11
| | | | | | | | | | | | | - struct_2.ll: Completely unaligned load/store testing - call_indirect.ll, struct_1.ll: Add test lines to exercise X-form [$reg($reg)] addressing At this point, loads and stores should be under control (he says in an optimistic tone of voice.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45882 91177308-0d34-0410-b5e6-96231b3b80d8
* More CellSPU refinement and progress:Scott Michel2008-01-111-0/+29
- Cleaned up custom load/store logic, common code is now shared [see note below], cleaned up address modes - More test cases: various intrinsics, structure element access (load/store test), updated target data strings, indirect function calls. Note: This patch contains a refactoring of the LoadSDNode and StoreSDNode structures: they now share a common base class, LSBaseSDNode, that provides an interface to their common functionality. There is some hackery to access the proper operand depending on the derived class; otherwise, to do a proper job would require finding and rearranging the SDOperands sent to StoreSDNode's constructor. The current refactor errs on the side of being conservatively and backwardly compatible while providing functionality that reduces redundant code for targets where loads and stores are custom-lowered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45851 91177308-0d34-0410-b5e6-96231b3b80d8
