2011-06-20PTX: Add basic register spilling codeJustin Holewinski
The current implementation generates stack loads/stores, which are really just mov instructions from/to "special" registers. This may not be the most efficient implementation, compared to an approach where the stack registers are directly folded into instructions, but this is easier to implement and I have yet to see a case where ptxas is unable to see through this kind of register usage and know what is really going on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133443 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-20Change how PHINodes store their operands.Jay Foad
Change PHINodes to store simple pointers to their incoming basic blocks, instead of full-blown Uses. Note that this loses an optimization in SplitCriticalEdge(), because we can no longer walk the use list of a BasicBlock to find phi nodes. See the comment I removed starting "However, the foreach loop is slow for blocks with lots of predecessors". Extend replaceAllUsesWith() on a BasicBlock to also update any phi nodes in the block's successors. This mimics what would have happened when PHINodes were proper Users of their incoming blocks. (Note that this only works if OldBB->replaceAllUsesWith(NewBB) is called when OldBB still has a terminator instruction, so it still has some successors.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133435 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-20Make better use of the PHINode API.Jay Foad
Change various bits of code to make better use of the existing PHINode API, to insulate them from forthcoming changes in how PHINodes store their operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133434 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-20Remove the AugmentedUse struct.Jay Foad

2011-06-20Revamp the "ConstantStruct::get" methods. Previously, these were scatteredChris Lattner
all over the place in different styles and variants. Standardize on two preferred entrypoints: one that takes a StructType and ArrayRef, and one that takes StructType and varargs. In cases where there isn't a struct type convenient, we now add a ConstantStruct::getAnon method (whose name will make more sense after a few more patches land). It would be "really really nice" if the ConstantStruct::get and ConstantVector::get methods didn't make temporary std::vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133412 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-20Add a RegisterTuples class to Target.td and TableGen.Jakob Stoklund Olesen
A RegisterTuples instance is used to synthesize super-registers by zipping together lists of sub-registers. This is useful for generating pseudo-registers representing register sequence constraints like 'two consecutive GPRs', or 'an even-odd pair of floating point registers'. The RegisterTuples def can be used in register set operations when building register classes. That is the only way of accessing the synthesized super-registers. For example, the ARM QQ register class of pseudo-registers could have been formed like this: // Form pairs Q0_Q1, Q2_Q3, ... def QQPairs : RegisterTuples<[qsub_0, qsub_1], [(decimate QPR, 2), (decimate (shl QPR, 1), 2)]>; def QQ : RegisterClass<..., (add QQPairs)>; Similarly, pseudo-registers representing '3 consecutive D-regs with wraparound' look like: // Form D0_D1_D2, D1_D2_D3, ..., D30_D31_D0, D31_D0_D1. def DSeqTriples : RegisterTuples<[dsub_0, dsub_1, dsub_2], [(rotl DPR, 0), (rotl DPR, 1), (rotl DPR, 2)]>; TableGen automatically computes aliasing information for the synthesized registers. Register tuples are still somewhat experimental. We still need to see how they interact with MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133407 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-18Fix PR10103: Less code for enum type translation.Hans Wennborg
In cases such as the attached test, where the case value for a switch destination is used in a phi node that follows the destination, it might be better to replace that value with the condition value of the switch, so that more blocks can be folded away with TryToSimplifyUncondBranchFromEmptyBlock because there are less conflicts in the phi node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133344 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-18When scalar replacement returns a vector type, only accept it if the vectorCameron Zwarich
type's bitwidth matches the (allocated) size of the alloca. This severely pessimizes vector scalar replacement when the only vector type being used is something like <3 x float> on x86 or ARM whose allocated size matches a <4 x float>. I hope to fix some of the flawed assumptions about allocated size throughout scalar replacement and reenable this in most cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133338 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-18Remove MethodProtos/MethodBodies and allocation_order_begin/end.Jakob Stoklund Olesen
Targets that need to change the default allocation order should use the AltOrders mechanism instead. See the X86 and ARM targets for examples.
