* Add initial support for debug countingDaniel Berlin2017-02-193-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We have support for bisection, and bugpoint can reduce testcases often to a single pass. But that doesn't help reduce it to a single transform by a single pass. Which debug counting lets us do. Debug counting lets you instrument a pass so that it only executes a certain thing (rwhatever you want) after skipping it a certain time of times, and then only does a certain number of executions before saying "skip" again. To make it concrete, for predicateinfo, if i instrument use renaming, i can make it so it skips renaming the first N uses, renames the next N, and then skips the rest. This lets you narrow down a miscompilation to, often, a single transformation, and then also debug it (by using the same command line parameters).

* Revert "[COFF] support /ERRORLIMIT option"David Blaikie2017-02-195-92/+29
| | | | | | | | | | | | | Behavior races on ErrorCount. If the enqueued paths are evaluated eagerly (in enqueuePath) then the behavior is as the test expects. But they may not be evaluated until the future is waited on, in run() - which is after the early return/exit on ErrorCount. (this causes the test to fail (because in the "/ERRORCOUNT:XYZ" test, no other errors are printed), at least for me, on linux) This reverts commit r295507. llvm-svn: 295590

* [ScopInfo] Count read-only arrays when computing complexity of alias checkTobias Grosser2017-02-182-1/+227
| | | | | | | | | | | Instead of counting the number of read-only accesses, we now count the number of distinct read-only array references when checking if a run-time alias check may be too complex. The run-time alias check is quadratic in the number of base pointers, not the number of accesses. Before this change we accidentally skipped SPEC's lbm test case. llvm-svn: 295567

* Revert "[X86] Remove XOP VPCMOV intrinsics and autoupgrade them to native IR."Craig Topper2017-02-187-94/+89
| | | | | | This reverts r295564. I missed that clang was still using the intrinsics despite our half implemented autoupgrade support. llvm-svn: 295565
* [X86] Remove XOP VPCMOV intrinsics and autoupgrade them to native IR.Craig Topper2017-02-187-89/+94
| | | | | | It seems we were already upgrading 128-bit VPCMOV, but the intrinsic was still defined and being used in isel patterns. While I was here I also simplified the tablegen multiclasses. llvm-svn: 295564

* Revert "threading_support: make __thread_sleep_for be alertable"Saleem Abdulrasool2017-02-181-5/+3
| | | | | | | | | This reverts SVN r295329. Although `__libcpp_thread_sleep_for` should be alertable, the implementation causes a large regression in the test suite. Add a FIXME item there for now to get the test suite in a better state before attempting to fix that behaviour. llvm-svn: 295561
* test: silence warnings on clang under clang-clSaleem Abdulrasool2017-02-181-1/+1
| | | | | | | When running under clang-cl mode, we do not define `__GNUC__`, resulting in the test failing. llvm-svn: 295560
* math: add type promoting template definition on MSVCRTSaleem Abdulrasool2017-02-181-0/+20
| | | | | | | | When building with MSVCRT, we need to manually provide the type promoting overloads to allow the correct type deduced invocation for signbit(Int) and fpclassify(int). llvm-svn: 295559
* test: explicitly size enumerationSaleem Abdulrasool2017-02-181-1/+1
| | | | | | | On certain targets, enumerations may be smaller than an `unsigned long`. Use an explicitly sized enumeration. llvm-svn: 295558

* Refactor instruction simplification code in visitors. NFC.Easwaran Raman2017-02-181-88/+67
| | | | | | | | | | | | | | Several visitors check if operands to the instruction are constants, either as it is or after looking up SimplifiedValues, check if the result is a constant and update the SimplifiedValues map. This refactoring splits it into a common function that does the checking of whether the operands are constants and updating of the SimplifiedValues table, and an instruction specific part that is implemented by each instruction visitor as a lambda and passed to the common function.
