* [PlaceSafepoints] Switch to being a FunctionPassPhilip Reames2015-05-121-11/+6
| | | | | | | | The pass doesn't actually modify the module outside of the function being processed. The only confusing piece is that it both inserts calls and then inlines the resulting calls. Given that, it definitely invalidates module level analysis results, but many FunctionPasses do that. Differential Revision: http://reviews.llvm.org/D9590 llvm-svn: 237185
* [PlaceSafepoints] Make internal helper pass a FunctionPassPhilip Reames2015-05-121-11/+30
| | | | | | | | | | Switch from using a LoopPass to using a FunctionPass for the internal helper analysis pass. The next step is going to be to make this a true analysis pass which is required by the PlaceSafepoints pass itself. p.s. The interesting semantic part here is that we're changing the iteration order over the loops. It shouldn't matter, but that's the reason to separate this into it's own distinct patch.

* ARM: Remove Itineraries for swift CPUMatthias Braun2015-05-121-1046/+0
| | | | | | | | | | They do more harm than good when used in the MachineScheduler as they tend to take preference to register pressure minimsation which is more important for swift. Differential Revision: http://reviews.llvm.org/D9718 llvm-svn: 237179
* [PlaceSafepoints] Use analysis infrastructure to get dominator treePhilip Reames2015-05-121-6/+4
| | | | | | | | The old code computed dominators for every loop. This was terribly slow with no good reason. Just use the standard infrastructure for analysis passes. Differential Revision: http://reviews.llvm.org/D9586 llvm-svn: 237176

| | | | | | | | | | | | | | | | | | | Summary: This rule was always in the old SysV i386 ABI docs and the new ones that H.J. Lu has put together, but we never noticed: EAX scratch register; also used to return integer and pointer values from functions; also stores the address of a returned struct or union Fixes PR23491.

* [PlaceSafepoints] Remove dependence on LoopSimplifyPhilip Reames2015-05-121-29/+40
| | | | | | | | As a step towards getting rid of internal pass manager hack entirely, remove the need for loop simplify to run in the inner pass manager. The new code does produce slightly different loop structures, so this isn't technically NFC. Differential Revision: http://reviews.llvm.org/D9585 llvm-svn: 237172
* Convert PHI getIncomingValue() to foreach over incoming_values(). NFC.Pete Cooper2015-05-1217-49/+40

| | | | | | | | | | | | AMDGPU::SI_SPILL_V96_RESTORE was missing from a switch statement, which caused the srsrc and soffset register to not be set correctly. This commit replaces the switch statement with a SITargetInfo query to make sure all spill instructions are covered. Differential Revision: http://reviews.llvm.org/D9582 llvm-svn: 237164

* Reimplement heuristic for estimating complete-unroll optimization effects.Michael Zolotukhin2015-05-121-248/+300
| | | | | | | | | | | | | | | | | | | | Summary: This patch reimplements heuristic that tries to estimate optimization beneftis from complete loop unrolling. In this patch I kept the minimal changes - e.g. I removed code handling branches and folding compares. That's a promising area, but now there are too many questions to discuss before we can enable it. Test Plan: Tests are included in the patch.

* [Mips] Return false for isFPCloseToIncomingSP()Petar Jovanovic2015-05-121-0/+2
| | | | | | | | | | | | | On Mips, frame pointer points to the same side of the frame as the stack pointer. This function is used to decide where to put register scavenging spill slot. So far, it was put on the wrong side of the frame, and thus it was too far away from $fp when frame was larger than 2^15 bytes. Patch by Vladimir Radosavljevic. http://reviews.llvm.org/D8895 llvm-svn: 237153
* R600/SI: add pass to mark CF live ranges as non-spillableTom Stellard2015-05-124-0/+110
| | | | | | | | | | | | | | | | | | | | | | Spilling can insert instructions almost anywhere, and this can mess up control flow lowering in a multitude of ways, due to instruction reordering. Let's sort this out the easy way: never spill registers involved with control flow, i.e. saved EXEC masks. Unfortunately, this does not work at all with optimizations disabled, as the register allocator ignores spill weights. This should be addressed in a future commit. The test was reduced from the "stacks" shader of [1]. Some issues trigger the machine verifier while another one is checked manually. [1] http://madebyevan.com/webgl-path-tracing/ v2: only insert pass with optimizations enabled, merge test runs. Patch by: Grigori Goronzy llvm-svn: 237152

* R600/SI: Update tablegen defs to avoid restoring spilled sgprs to m0Tom Stellard2015-05-122-9/+4
| | | | | | | | We had code to do this in SIRegisterInfo::eliminateFrameIndex(), but it is easier to just change the definition of SI_SPILL_S32_RESTORE to only allow numbered sgprs. llvm-svn: 237143

* R600/SI: Remove explicit m0 operand from DS instructionsTom Stellard2015-05-126-118/+259

| | | | | | | | | | | | | | | Instead add m0 as an implicit operand. This allows us to avoid using the M0Reg register class and eliminates a number of unnecessary spills when using s_sendmsg instructions.

* AVX-512, X86: Added lowering for shift operations for SKX.Elena Demikhovsky2015-05-121-101/+65

* [ARM] Use AEABI aligned function variantsJohn Brawn2015-05-122-51/+141
| | | | | | | | | | | AEABI defines aligned variants of memcpy etc. that can be faster than the default version due to not having to do alignment checks. When emitting target code for these functions make use of these aligned variants if possible. Also convert memset to memclr if possible.

* Reverse ordering of base and derived pointer during safepoint lowering.Igor Laevsky2015-05-121-10/+12
| | | | | | | | According to the documentation in StackMap section for the safepoint we should have: "The first Location in each pair describes the base pointer for the object. The second is the derived pointer actually being relocated." But before this change we emitted them in reverse order - derived pointer first, base pointer second. llvm-svn: 237126
* [X86] Remove useless target specific combine on TRUNCATE dag nodes.Andrea Di Biagio2015-05-121-11/+0
| | | | | | | | | | | | | Before revision 171146, function 'PerformTruncateCombine' used to perform a premature lowering of TRUNCATE dag nodes. Revision 171146 then moved all the logic implemented by PerformTruncateCombine to a custom lowering hook. However, that revision forgot to delete function PerformTruncateCombine from the code. This patch removes function 'PerformTruncateCombine' since it has no effect on the SelectionDAG. No functional change intended. llvm-svn: 237122

* Migrate existing backends that care about software floating pointEric Christopher2015-05-1218-48/+81
| | | | | | | | | | | | | | | | | | | | to use the information in the module rather than TargetOptions. We've had and clang has used the use-soft-float attribute for some time now so have the backends set a subtarget feature based on a particular function now that subtargets are created based on functions and function attributes. For the one middle end soft float check go ahead and create an overloadable TargetLowering::useSoftFloat function that just checks the TargetSubtargetInfo in all cases. Also remove the command line option that hard codes whether or not soft-float is set by using the attribute for all of the target specific test cases - for the generic just go ahead and add the attribute in the one case that showed up. llvm-svn: 237079
