* include/llvm: Add R600 Intrinsics v6Tom Stellard2012-07-16

* Add support for attaching branch weight metadata directly from the IRBuilder.Chandler Carruth2012-07-16
| | | | | | | | | 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. Fortunately, the two share all the interesting code paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160251 91177308-0d34-0410-b5e6-96231b3b80d8
* Move llvm/Support/TypeBuilder.h -> llvm/TypeBuilder.h. This completesChandler Carruth2012-07-15
| | | | | | | | | | | | the move of *Builder classes into the Core library. No uses of this builder in Clang or DragonEgg I could find. If there is a desire to have an IR-building-support library that contains all of these builders, that can be easily added, but currently it seems likely that these add no real overhead to VMCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160243 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor the code that checks that all operands of a node are UNDEFs.Nadav Rotem2012-07-15
| | | | | | | | | | | Add a micro-optimization to getNode of CONCAT_VECTORS when both operands are undefs. Can't find a testcase for this because VECTOR_SHUFFLE already handles undef operands, but Duncan suggested that we add this.

* Add support for dynamic stack realignment in the presence of dynamic allocas onChad Rosier2012-07-10
| | | | | | | | | | | | | | 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

* Allow intrinsics to be used in place of node matchables.Jim Grosbach2012-07-10
| | | | | | | | | | | | | | | | | | | | | | 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

* I'm introducing a new machine model to simultaneously allow simpleAndrew Trick2012-07-07
| | | | | | | | | | | | | | | | | | | | | | | 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

* Finish fixing the MachineOperand hashing, providing a nice modernChandler Carruth2012-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | hash_value overload for MachineOperands. This addresses a FIXME sufficient for me to remove it, and cleans up the code nicely too. The important changes to the hashing logic: - TargetFlags are now included in all of the hashes. These were complete missed. - Register operands have their subregisters and whether they are a def included in the hash. - We now actually hash all of the operand types. Previously, many operand types were simply *dropped on the floor*. For example: - Floating point immediates - Large integer immediates (>64-bit) - External globals! - Register masks - Metadata operands - It removes the offset from the block-address hash; I'm a bit suspicious of this, but isIdenticalTo doesn't consider the offset for black addresses. Any patterns involving these entities could have triggered extreme slowdowns in MachineCSE or PHIElimination. Let me know if there are PRs you think might be closed now... I'm looking myself, but I may miss them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159743 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an experimental early if-conversion pass, off by default.Jakob Stoklund Olesen2012-07-04
| | | | | | | | | | | | | This pass performs if-conversion on SSA form machine code by speculatively executing both sides of the branch and using a cmov instruction to select the result. This can help lower the number of branch mispredictions on architectures like x86 that don't have predicable instructions. The current implementation is very aggressive, and causes regressions on mosts tests. It needs good heuristics that have yet to be implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159694 91177308-0d34-0410-b5e6-96231b3b80d8

* Extend TargetPassConfig to allow running only a subset of the normal passes.Bob Wilson2012-07-02
| | | | | | | | | | | | | | | | | This is still a work in progress but I believe it is currently good enough to fix PR13122 "Need unit test driver for codegen IR passes". For example, you can run llc with -stop-after=loop-reduce to have it dump out the IR after running LSR. Serializing machine-level IR is not yet supported but we have some patches in progress for that. The plan is to serialize the IR to a YAML file, containing separate sections for the LLVM IR, machine-level IR, and whatever other info is needed. Chad suggested that we stash the stop-after pass in the YAML file and use that instead of the start-after option to figure out where to restart the compilation. I think that's a great idea, but since it's not implemented yet I put the -start-after option into this patch for testing purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159570 91177308-0d34-0410-b5e6-96231b3b80d8
