2012-07-17Allow for customized graph edge pruning in PostOrderIterator.hJakob Stoklund Olesen
Make it possible to prune individual graph edges from a post-order traversal by specializing the po_iterator_storage template. Previously, it was only possible to prune full graph nodes. Edge pruning makes it possible to remove loop back-edges, for example. Also replace the existing DFSetTraits customization hook with a po_iterator_storage method for observing the post-order. DFSetTraits was only used by LoopIterator.h which now provides a po_iterator_storage specialization. Thanks to Sean and Chandler for reviewing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160366 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-17TableGen: Allow conditional instruction pattern in multiclass.Jim Grosbach
Define a 'null_frag' SDPatternOperator node, which if referenced in an instruction Pattern, results in the pattern being collapsed to be as-if '[]' had been specified instead. This allows supporting a multiclass definition where some instaniations have ISel patterns associated and others do not. For example, multiclass myMulti<RegisterClass rc, SDPatternOperator OpNode = null_frag> { def _x : myI<(outs rc:), (ins rc:), []>; def _r : myI<(outs rc:), (ins rc:), [(set rc:, (OpNode rc:))]>; } defm foo : myMulti<GRa, not>; defm bar : myMulti<GRb>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160333 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16Add support for attaching branch weight metadata directly from the IRBuilder.Chandler Carruth
Added a basic unit test for this with CreateCondBr. I didn't go all the way and test the switch side as the boilerplate for setting up the switch IRBuilder unit tests is a lot more.

2012-07-15Move llvm/Support/TypeBuilder.h -> llvm/TypeBuilder.h. This completesChandler Carruth
the move of *Builder classes into the Core library. No uses of this builder in Clang or DragonEgg I could find.

2012-07-10Add support for dynamic stack realignment in the presence of dynamic allocas onChad Rosier
X86. Basically, this is a reapplication of r158087 with a few fixes. Specifically, (1) the stack pointer is restored from the base pointer before popping callee-saved registers and (2) in obscure cases (see comments in patch) we must cache the value of the original stack adjustment in the prologue and apply it in the epilogue. rdar://11496434 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160002 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-10Allow intrinsics to be used in place of node matchables.Jim Grosbach
TableGen has support for using an intrinics name directly in a DAG, but this breaks down when referring to just a node, as that's handled initializer list stuff entirely via subclassing in the parser. That is, using an instrinsic like "(int_my_intrinsic ...)" works fine. Using it standalone for parameterizing the operator in such a DAG does not. Fixing this is simple enough, as we simply declare Intrinsic as deriving from SDPatternOperator, which is the class name intended for exactly this purpose in TargetSelectionDAG.td. When the intrinsic is actually used in the DAG pattern, it will be recognized and expanded to an intrinsic_wo_chain (et. al.) just like when it's used directly. Incoming ARM NEON cleanup based on this and a bit of functionality improvement after that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159973 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-07I'm introducing a new machine model to simultaneously allow simpleAndrew Trick
subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159891 91177308-0d34-0410-b5e6-96231b3b80d8
