* code hoisting pass based on GVNSebastian Pop2016-07-0110-4/+1418
| | | | | | | | | | | | | This pass hoists duplicated computations in the program. The primary goal of gvn-hoist is to reduce the size of functions before inline heuristics to reduce the total cost of function inlining. Pass written by Sebastian Pop, Aditya Kumar, Xiaoyu Hu, and Brian Rzycki. Important algorithmic contributions by Daniel Berlin under the form of reviews. Differential Revision: http://reviews.llvm.org/D19338 llvm-svn: 274305
* Target: Remove unused arguments from overrideSchedPolicy, NFCDuncan P. N. Exon Smith2016-07-019-16/+3
| | | | | | | | | | TargetSubtargetInfo::overrideSchedPolicy takes two MachineInstr* arguments (begin and end) that invite implicit conversions from MachineInstrBundleIterator. One option would be to change their type to an iterator, but since they don't seem to have been used since the API was added in 2010, I'm deleting the dead code. llvm-svn: 274304
* CodeGen: Use MachineInstr& in MachineSink, NFCDuncan P. N. Exon Smith2016-07-011-52/+49
| | | | | | | Use MachineInstr& instead of MachineInstr* in MachineSinker to help avoid implicit conversions from iterator to pointer. llvm-svn: 274303

* CodeGen: Use MachineInstr& more in MachineTraceMetrics, NFCDuncan P. N. Exon Smith2016-07-011-20/+20
| | | | | | | | Push MachineInstr& through helper APIs for consistency. This doesn't remove any more implicit conversions, but it's a nice cleanup after r274300. llvm-svn: 274301
* CodeGen: Use MachineInstr& in MachineTraceMetrics, NFCDuncan P. N. Exon Smith2016-06-301-14/+14

* CodeGen: Use MachineInstr& in LocalStackSlotAllocation, NFCDuncan P. N. Exon Smith2016-06-301-35/+29
| | | | | | | Avoid a number of implicit conversions from iterator to pointer by using range-based for and MachineInstr&. llvm-svn: 274298
* CodeGen: Use range-based for in LiveVariables, NFCDuncan P. N. Exon Smith2016-06-301-6/+4

* CodeGen: Use MachineInstr& in LDVImpl::handleDebugValue, NFCDuncan P. N. Exon Smith2016-06-301-14/+13

* Add LoadStoreVectorizer passMatt Arsenault2016-06-3013-1/+1825

* CodeGen: Use MachineInstr& in ExpandISelPseudos, NFCDuncan P. N. Exon Smith2016-06-301-3/+3
| | | | | | | Avoid another implicit conversion from MachineInstrBundleIterator to MachineInstr* by using MachineInstr&. llvm-svn: 274292
* CodeGen: Use MachineInstr& in IfConversion, NFCDuncan P. N. Exon Smith2016-06-301-9/+9
| | | | | | | | Switch to a range-based for in IfConverter::PredicateBlock and take MachineInstr& in MaySpeculate to avoid an implicit conversion from MachineBasicBlock::iterator to MachineInstr*. llvm-svn: 274290

* [TableGen] Use a SmallVector for Record::Values to avoid debug iteratorsReid Kleckner2016-06-301-3/+3
| | | | | | | | | | | | | Debug iterators are valuable so we don't want to turn them off completely. However, llvm-tblgen is critical to build speed, so we can skip them here. Regenerating X86GenSubtargetInfo.inc in a clang-cl self-host debug build now takes 39s instead of 1m29s. Helps PR28222 llvm-svn: 274288
* CodeGen: Use MachineInstr& in TargetLowering, NFCDuncan P. N. Exon Smith2016-06-3036-1257/+1338
| | | | | | | | | | | | | This is a mechanical change to make TargetLowering API take MachineInstr& (instead of MachineInstr*), since the argument is expected to be a valid MachineInstr. In one case, changed a parameter from MachineInstr* to MachineBasicBlock::iterator, since it was used as an insertion point. As a side effect, this removes a bunch of MachineInstr* to MachineBasicBlock::iterator implicit conversions, a necessary step toward fixing PR26753. llvm-svn: 274287

* [CMake] Module builds depend on target intrinsics_gen to be built first.Vassil Vassilev2016-06-301-0/+9
| | | | | | | | | | | | | | When compiling with modules, header A and B can be in the same module M. B depends on intrinsics_gen and A doesn't. Compiling a source file #include-ing header A, we implicitly request module M to be built. It puts header A and B in the same TU and tries to build them. Since B depends on intrinsics_gen (which might not be built yet) we run into build failures. This should fix our modules buildbot. Patch reviewed by Chris Bieneman. llvm-svn: 274270
* Introduce a *draft* of a code of conduct for the LLVM community and theChandler Carruth2016-06-303-0/+256
| | | | | | | | | | | | | | | | | | | | | | | | | | | associated reporting guide. I want to emphasize that at this point these are just drafts! This is the result of very extended discussion on the mailing lists on several different threads: http://lists.llvm.org/pipermail/llvm-dev/2015-October/091218.html http://lists.llvm.org/pipermail/llvm-dev/2016-May/099120.html http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151019/307070.html The reporting guide in particular I anticipate will be shaped somewhat by the advisory committee when they are selected. But hopefully this serves as a good starting point and good guidance while the advisory committee is being sorted out. I'd like to thank all the folks who contributed to this. Many, *many* people worked to help with drafting, wording, suggestions, and edits. Also, this is based on widely used existing codes of coduct as mentioned in the text, and the original authors of those deserve many thanks as well.

* [InstCombine] shrink switch conditions better (PR24766)Sanjay Patel2016-06-303-47/+28
| | | | | | | | | | | | | | https://llvm.org/bugs/show_bug.cgi?id=24766#c2 This removes a hack that was added for the benefit of x86 codegen. It prevented shrinking the switch condition even to smaller legal (DataLayout) types. We have a safety mechanism in CGP after: http://reviews.llvm.org/rL251857 ...so we're free to use the optimal (smallest) IR type now.
