* DebugInfo: Move type units into the debug_types section with appropriate ↵David Blaikie2013-12-13
| | | | | | | | | | | | | | | | | | | comdat grouping and type unit headers This commit does not complete the type units feature - there are issues around fission support (skeletal type units, pubtypes/pubnames) and hashing of some types including those containing references to types in other type units. Originally committed as r197073 and reverted in r197079. This commit originally got jumbled up with another build-breaking commit and I can't find the failures I thought this caused anymore.

* Fix a use-after-free error in GlobalOpt CleanupConstantGlobalUsersHal Finkel2013-12-12
| | | | | | | | | | | | GlobalOpt's CleanupConstantGlobalUsers function uses a worklist array to manage constant users to be visited. The pointers in this array need to be weak handles because when we delete a constant array, we may also be holding a pointer to one of its elements (or an element of one of its elements if we're dealing with an array of arrays) in the worklist. Fixes PR17347. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197178 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | The barrier pass is a temporary hack, and should go away soon.

* Improve instruction scheduling for the PPC POWER7Hal Finkel2013-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aside from a few minor latency corrections, the major change here is a new hazard recognizer which focuses on better dispatch-group formation on the POWER7. As with the PPC970's hazard recognizer, the most important thing it does is avoid load-after-store hazards within the same dispatch group. It uses the POWER7's special dispatch-group-terminating nop instruction (instead of inserting multiple regular nop instructions). This new hazard recognizer makes use of the scheduling dependency graph itself, built using AA information, to robustly detect the possibility of load-after-store hazards. significant test-suite performance changes (the error bars are 99.5% confidence intervals based on 5 test-suite runs both with and without the change -- speedups are negative): speedups: MultiSource/Benchmarks/FreeBench/pcompress2/pcompress2 -0.55171% +/- 0.333168% MultiSource/Benchmarks/TSVC/CrossingThresholds-dbl/CrossingThresholds-dbl -17.5576% +/- 14.598% MultiSource/Benchmarks/TSVC/Reductions-dbl/Reductions-dbl -29.5708% +/- 7.09058% MultiSource/Benchmarks/TSVC/Reductions-flt/Reductions-flt -34.9471% +/- 11.4391% SingleSource/Benchmarks/BenchmarkGame/puzzle -25.1347% +/- 11.0104% SingleSource/Benchmarks/Misc/flops-8 -17.7297% +/- 9.79061% SingleSource/Benchmarks/Shootout-C++/ary3 -35.5018% +/- 23.9458% SingleSource/Regression/C/uint64_to_float -56.3165% +/- 25.4234% SingleSource/UnitTests/Vectorizer/gcc-loops -18.5309% +/- 6.8496% regressions: MultiSource/Benchmarks/ASCI_Purple/SMG2000/smg2000 18.351% +/- 12.156% SingleSource/Benchmarks/Shootout-C++/methcall 27.3086% +/- 14.4733% git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197099 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix an over-constrained assertion in MachineFunction::addLiveIn.Quentin Colombet2013-12-12
| | | | | | | | | | | | | | | | | The assertion was checking that the virtual register VReg used to represent the physical register PReg uses the same register class as the one passed to MachineFunction::addLiveIn. This is over-constraining because it is sufficient to check that the register class of VReg (VRegRC) is a subclass of the register class of PReg (PRegRC) and that VRegRC contains PReg. Indeed, if VReg gets constrained because of some operation constraints between two calls of MachineFunction::addLiveIn, the original assertion cannot match. This fixes <rdar://problem/15633429>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197097 91177308-0d34-0410-b5e6-96231b3b80d8

* Add two additional hazard recognizer functionsHal Finkel2013-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds two additional functions to the hazard recognizer interface. These are optional (in the sense that the default implementations preserve the current behavior), and used by the post-RA scheduler. Upcoming commits will use this functionality in order to improve dispatch-group formation on the POWER7 and related cores. Dispatch groups are an odd construct: sometimes we need to insert nops to force a new one to start (for performance reasons), and some instructions need to appear in certain positions within a group, but the groups are not fundamentally cycle based (they can contain instructions with data dependencies with non-trivial latencies). Motivation: unsigned PreEmitNoops(SUnit *) - Used to force the post-RA scheduler to insert nops to force a new dispatch group to begin. We already have a NoopHazard, and this is also still needed. However, NoopHazard only causes a nop to be inserted if there are no other available instructions, and so is not always sufficient. The number of nops to insert depends on state that only the hazard recognizer has, so a general callback is necessary. bool ShouldPreferAnother(SUnit *) - Used to avoid scheduling instructions that would start a new dispatch group when others are available that could be part of the current dispatch group. In this case, we don't want to issue nops, because the non-preferred instruction will implicitly start a new dispatch group regardless. Although the motivation for these functions is driven by the PowerPC backend, they are completely general. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197084 91177308-0d34-0410-b5e6-96231b3b80d8
