* Fix PR18361: Invalidate LoopDispositions after LoopSimplify hoists things.Andrew Trick2014-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getSCEV for an ashr instruction creates an intermediate zext expression when it truncates its operand. The operand is initially inside the loop, so the narrow zext expression has a non-loop-invariant loop disposition. LoopSimplify then runs on an outer loop, hoists the ashr operand, and properly invalidate the SCEVs that are mapped to value. The SCEV expression for the ashr is now an AddRec with the hoisted value as the now loop-invariant start value. The LoopDisposition of this wide value was properly invalidated during LoopSimplify. However, if we later get the ashr SCEV again, we again try to create the intermediate zext expression. We get the same SCEV that we did earlier, and it is still cached because it was never mapped to a Value. When we try to create a new AddRec we abort because we're using the old non-loop-invariant LoopDisposition. I don't have a solution for this other than to clear LoopDisposition when LoopSimplify hoists things. I think the long-term strategy should be to perform LoopSimplify on all loops before computing SCEV and before running any loop opts on individual loops. It's possible we may want to rerun LoopSimplify on individual loops, but it should rarely do anything, so rarely require invalidating SCEV. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198478 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a LLVM_DUMP_METHOD macro.Nico Weber2014-01-03
| | | | | | | | | | | | | | | | The motivation is to mark dump methods as used in debug builds so that they can be called from lldb, but to not do so in release builds so that they can be dead-stripped.

* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-03
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198438 91177308-0d34-0410-b5e6-96231b3b80d8

* [RegAlloc] Make tryInstructionSplit less aggressive.Quentin Colombet2014-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The greedy register allocator tries to split a live-range around each instruction where it is used or defined to relax the constraints on the entire live-range (this is a last chance split before falling back to spill). The goal is to have a big live-range that is unconstrained (i.e., that can use the largest legal register class) and several small local live-range that carry the constraints implied by each instruction. E.g., Let csti be the constraints on operation i. V1= op1 V1(cst1) op2 V1(cst2) V1 live-range is constrained on the intersection of cst1 and cst2. tryInstructionSplit relaxes those constraints by aggressively splitting each def/use point: V1= V2 = V1 V3 = V2 op1 V3(cst1) V4 = V2 op2 V4(cst2) Because of how the coalescer infrastructure works, each new variable (V3, V4) that is alive at the same time as V1 (or its copy, here V2) interfere with V1. Thus, we end up with an uncoalescable copy for each split point. To make tryInstructionSplit less aggressive, we check if the split point actually relaxes the constraints on the whole live-range. If it does not, we do not insert it. Indeed, it will not help the global allocation problem: - V1 will have the same constraints. - V1 will have the same interference + possibly the newly added split variable VS. - VS will produce an uncoalesceable copy if alive at the same time as V1. <rdar://problem/15570057> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198369 91177308-0d34-0410-b5e6-96231b3b80d8
* Disable compare sinking in CodeGenPrepare when multiple condition registers ↵Hal Finkel2014-01-02
| | | | | | | | | | | | | | | | | | | are available As noted in the comment above CodeGenPrepare::OptimizeInst, which aggressively sinks compares to reduce pressure on the condition register(s), for targets such as PowerPC with multiple condition registers, this may not be the right thing to do. This adds an HasMultipleConditionRegisters boolean to TLI, and CodeGenPrepare::OptimizeInst is skipped when HasMultipleConditionRegisters is true. This functionality will be used by the PowerPC backend in an upcoming commit. Especially when the PowerPC backend starts tracking individual condition register bits as separate allocatable entities (which will happen in this upcoming commit), this sinking from CodeGenPrepare::OptimizeInst is significantly suboptimial. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198354 91177308-0d34-0410-b5e6-96231b3b80d8
