| 2016-08-03 | Adding -verify-machineinstrs option to PowerPC tests | Ehsan Amiri | |
| Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277624 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
| 2013-07-09 | Don't crash in SE dealing with ashr x, -1 | Hal Finkel | |
| ScalarEvolution::getSignedRange uses ComputeNumSignBits from ValueTracking on ashr instructions. ComputeNumSignBits can return zero, but this case was not handled correctly by the code in getSignedRange which was calling: APInt::getSignedMinValue(BitWidth).ashr(NS - 1) with NS = 0, resulting in an assertion failure in APInt::ashr. Now, we just return the conservative result (as with NS == 1). Another bug found by llvm-stress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185955 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
