* [BPI] Adjust the probability for floating point unordered comparisonGuozhi Wei2019-09-101-1/+2
| | | | | | | | Since NaN is very rare in normal programs, so the probability for floating point unordered comparison should be extremely small. Current probability is 3/8, it is too large, this patch changes it to a tiny number. Differential Revision: https://reviews.llvm.org/D65303 llvm-svn: 371541
* [SystemZ] Support conditional indirect sibling calls via BCRUlrich Weigand2016-04-111-0/+467
This adds a conditional variant of CallBR instruction, CallBCR. Also, it can be fused with integer comparisons, resulting in one of the new C*BCall instructions. In addition to CallBRCL limitations, this has another one: it won't trigger if the function to call isn't already in %r1 - see f22 in the test for an example (it's also why the loads in tests are volatile).
