2010-04-08Avoid using f64 to lower memcpy from constant string. It's cheaper to use ↵Evan Cheng
i32 store of immediates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100751 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-04Reapply address space patch after fixing an issue in MemCopyOptimizer.Mon P Wang
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset, e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100304 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-01- Avoid using floating point stores to implement memset unless the value is ↵Evan Cheng
zero. - Do not try to infer GV alignment unless its type is sized. It's not possible to infer alignment if it has opaque type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100118 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-01Fix sdisel memcpy, memset, memmove lowering:Evan Cheng
1. Makes it possible to lower with floating point loads and stores. 2. Avoid unaligned loads / stores unless it's fast. 3. Fix some memcpy lowering logic bug related to when to optimize a load from constant string into a constant. 4. Adjust x86 memcpy lowering threshold to make it more sane. 5. Fix x86 target hook so it uses vector and floating point memory ops more effectively. rdar://7774704 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100090 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-15Now that the default for Darwin platforms is to place the LSDA into the TEXTBill Wendling
section, remove the target-specific code that performs this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98580 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-12The same situation that effected ARM effects PPC with regards to placing theBill Wendling
LSDA into the TEXT section. We need to generate non-lazy pointers to it on Mach-O. However, the object the NLP points to may be local to the translation unit. If so, then the NLP needs to have the value of that object specified instead of "0", which the linker interprets as "external". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98325 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-09The address of an indirect call must be in R12 on Darwin.Dale Johannesen
Make it so. (This patch is in LowerCall_Darwin, which seems to be used by SVR4 code as well; since that doesn't belong here, I haven't worried about this case.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98077 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng
Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-22Add more plumbing. This time in the LowerArguments and "get" functions whichBill Wendling
return partial registers. This affected the back-end lowering code some. Also patch up some places I missed before in the "get" functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91880 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-23Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used.Dan Gohman
Note that "hasDotLocAndDotFile"-style debug info was already broken; people wanting this functionality should implement it in the AsmPrinter/DwarfWriter code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89711 91177308-0d34-0410-b5e6-96231b3b80d8

PPC is such a target; make it work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-12Add a bool flag to StackObjects telling whether they reference spillDavid Greene
slots. The AsmPrinter will use this information to determine whether to print a spill/reload comment. Remove default argument values. It's too easy to pass a wrong argument value when multiple arguments have default values. Make everything explicit to trap bugs early. Update all targets to adhere to the new interfaces.. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87022 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18-Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixedEvan Cheng
stack slots and giving them different PseudoSourceValue's did not fix the problem of post-alloc scheduling miscompiling llvm itself. - Apply Dan's conservative workaround by assuming any non fixed stack slots can alias other memory locations. This means a load from spill slot #1 cannot move above a store of spill slot #2. - Enable post-alloc scheduling for x86 at optimization leverl Default and above. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84424 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-27LBRX no longer has an explicit SrcValueSDNode operand, so the typeDan Gohman
operand is now at index 2, rather than 3. This fixes the "Invalid child # of SDNode!" failures on PowerPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82942 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Improve MachineMemOperand handling.Dan Gohman
- Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Rename getTargetNode to getMachineNode, for consistency with theDan Gohman
naming scheme used in SelectionDAG, where there are multiple kinds of "target" nodes, but "machine" nodes are nodes which represent a MachineInstr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82790 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-19Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic ↵Evan Cheng

2009-08-29- Add target lowering methods to get the preferred format for the FDE and LSDABill Wendling
encodings. - Make some of the values emitted by the FDEs dependent upon the pointer size. This is in line with how GCC does things. And it has the benefit of working for Darwin in 64-bit mode now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80428 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Add support for the PowerPC 64-bit SVR4 ABI.Tilmann Scheller
The Link Register is volatile when using the 32-bit SVR4 ABI. Make it possible to use the 64-bit SVR4 ABI. Add non-volatile registers for the 64-bit SVR4 ABI. Make sure r2 is a reserved register when using the 64-bit SVR4 ABI. Update PPCFrameInfo for the 64-bit SVR4 ABI. Add FIXME for 64-bit Darwin PPC. Insert NOP instruction after direct function calls. Emit official procedure descriptors. Create TOC entries for GlobalAddress references. Spill 64-bit non-volatile registers to the correct slots. Only custom lower VAARG when using the 32-bit SVR4 ABI. Use simple VASTART lowering for the 64-bit SVR4 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79091 91177308-0d34-0410-b5e6-96231b3b80d8
