2009-01-13Removoe MachineModuleInfo methods (and related DebugInfoDesc class ↵Devang Patel
hierarchy) that were used to handle debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62199 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-13The list-td and list-tdrr schedulers don't yet support physregDan Gohman
scheduling dependencies. Add assertion checks to help catch this. It appears the Mips target defaults to list-td, and it has a regression test that uses a physreg dependence. Such code was liable to be miscompiled, and now evokes an assertion failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62177 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-13When replacing uses and the same node is reachedDuncan Sands
via two paths, process it once not twice, d'oh! Analysis, testcase and original patch thanks to Mon Ping Wang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62169 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-12Rename getABITypeSize to getTypePaddedSize, asDuncan Sands
suggested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62099 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12Fix PR3241: Currently EmitCopyFromReg emits a copy from the physical ↵Evan Cheng
register to a virtual register unless it requires an expensive cross class copy. That means we are only treating "expensive to copy" register dependency as physical register dependency. Also future proof the scheduler to handle "normal" physical register dependencies. The code is not exercised yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62074 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-06Fix a bug in ComputeLinearIndex computation handling multi-levelDan Gohman
aggregate types. Don't increment the current index after reaching the end of a struct, as it will already be pointing at one-past-the end. This fixes PR3288. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61828 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06Update these argument lists for the isNormalMemoryDan Gohman
argument. This doesn't affect current functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61779 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06Use a latency value of 0 for the artificial edges inserted byDan Gohman
AddPseudoTwoAddrDeps. This lets the scheduling infrastructure avoid recalculating node heights. In very large testcases this was a major bottleneck. Thanks to Roman Levenstein for finding this! As a side effect, fold-pcmpeqd-0.ll is now scheduled better and it no longer requires spilling on x86-32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61778 91177308-0d34-0410-b5e6-96231b3b80d8

own OpActionsCapacity magic number; it can just use ISD::BUILTIN_OP_END, as long as it takes care to round up when needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61733 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-03CommuteNodesToReducePressure() is now removed.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61612 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-03Remove the code from the scheduler that commuted two-addressDan Gohman
instructions to avoid copies, because TwoAddressInstructionPass also does this optimization. The scheduler's version didn't account for live-out values, which resulted in spurious commutes and missed opportunities. Now, TwoAddressInstructionPass handles all the opportunities, instead of just those that the scheduler missed. The result is usually the same, though there are occasional trivial differences resulting from the avoidance of spurious commutes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61611 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-01Fix PR3274: when promoting the condition of a BRCOND node,Duncan Sands
promote from i1 all the way up to the canonical SetCC type. In order to discover an appropriate type to use, pass MVT::Other to getSetCCResultType. In order to be able to do this, change getSetCCResultType to take a type as an argument, not a value (this is also more logical). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61542 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-23Clean up the atomic opcodes in SelectionDAG.Dan Gohman
This removes all the _8, _16, _32, and _64 opcodes and replaces each group with an unsuffixed opcode. The MemoryVT field of the AtomicSDNode is now used to carry the size information. In tablegen, the size-specific opcodes are replaced by size-independent opcodes that utilize the ability to compose them with predicates. This shrinks the per-opcode tables and makes the code that handles atomics much more concise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61389 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-17Double the amount of memory reserved for SUnits. This is aDan Gohman
temporary workaround for an obscure bug. When node cloning is used, it is possible that more SUnits will be created, and if the SUnits std::vector has to reallocate, it will invalidate all the graph edges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61122 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-16We have decided not to support inline asm where an output operand with a ↵Evan Cheng
matching input operand with incompatible type (i.e. either one is a floating point and the other is an integer or the sizes of the types differ).

latency computation code that is no longer needed with the new method for handling latencies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61074 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-16Fix some register-alias-related bugs in the post-RA scheduler livenessDan Gohman
computation code. Also, avoid adding output-depenency edges when both defs are dead, which frequently happens with EFLAGS defs. Compute Depth and Height lazily, and always in terms of edge latency values. For the schedulers that don't care about latency, edge latencies are set to 1. Eliminate Cycle and CycleBound, and LatencyPriorityQueue's Latencies array. These are all subsumed by the Depth and Height fields. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61073 91177308-0d34-0410-b5e6-96231b3b80d8
