2009-11-30If pointer type has a name then do not ignore the name.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90172 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-30New virtual registers created for spill intervals should inherit allocation ↵Jakob Stoklund Olesen
hints from the original register. This helps us avoid silly copies when rematting values that are copied to a physical register: leaq _.str44(%rip), %rcx movq %rcx, %rsi call _strcmp becomes: leaq _.str44(%rip), %rsi call _strcmp The coalescer will not touch the movq because that would tie down the physical register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90163 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-30Reprioritize tests for tail duplication to be aggressive about indirectBob Wilson
branches even when optimizing for code size. Unless we find evidence to the contrary in the future, the special treatment for indirect branches does not have a significant effect on code size, and performance still matters with -Os. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90147 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-30Remove isProfitableToDuplicateIndirectBranch target hook. It is profitableBob Wilson
for all the processors where I have tried it, and even when it might not help performance, the cost is quite low. The opportunities for duplicating indirect branches are limited by other factors so code size does not change much due to tail duplicating indirect branches aggressively. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90144 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-30Added support to allow clients to custom widen. For X86, custom widen ↵Mon P Wang
vectors for divide/remainder since these operations can trap by unroll them and adding undefs for the resulting vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90108 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-26Rename new TailDuplicationPass to avoid name conflict with the old one.Bob Wilson

2009-11-26Split tail duplication into a separate pass. This is needed to avoidBob Wilson
running tail duplication when doing branch folding for if-conversion, and we also want to be able to run tail duplication earlier to fix some reg alloc problems. Move the CanFallThrough function from BranchFolding to MachineBasicBlock so that it can be shared by TailDuplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89904 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-25Use StringRef (again) in DebugInfo interface.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89866 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-24Refactor target hook for tail duplication as requested by Chris.Bob Wilson
Make tail duplication of indirect branches much more aggressive (for targets that indicate that it is profitable), based on further experience with this transformation. I compiled 3 large applications with and without this more aggressive tail duplication and measured minimal changes in code size. ("size" on Darwin seems to round the text size up to the nearest page boundary, so I can only say that any code size increase was less than one 4k page.) Radar 7421267. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89814 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-24<rdar://problem/6721894>. Allow multiple registers to be renamed together ↵David Goodwin
(super and sub) if necessary to break an anti-dependence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89722 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

no filename. This situation is apparently fairly common right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89701 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-23Move the FunctionLoweringInfo class and some related utility functions outDan Gohman
of SelectionDAGBuild.h/cpp into its own files, to help separate general lowering logic from SelectionDAG-specific lowering logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89667 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-22Add getFrameIndexReference() to TargetRegisterInfo, which allows targets toJim Grosbach
tell debug info which base register to use to reference a frame index on a per-index basis. This is useful, for example, in the presence of dynamic stack realignment when local variables are indexed via the stack pointer and stack-based arguments via the frame pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89620 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-21Be more clever about calculating live variables through new basic blocks.Jakob Stoklund Olesen
When splitting a critical edge, the registers live through the edge are: - Used in a PHI instruction, or - Live out from the predecessor, and - Live in to the successor. This allows the coalescer to eliminate even more phi joins. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89530 91177308-0d34-0410-b5e6-96231b3b80d8

and stores, handle the case where the element size is not a valid target type correctly (PPC). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89521 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21There is no need to use FoldingSet to unique DIEs. Devang Patel
DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89518 91177308-0d34-0410-b5e6-96231b3b80d8
