| * | [X86] Merge ISD::ADD/SUB nodes into X86ISD::ADD/SUB equivalents (PR40483) | Simon Pilgrim | 2019-02-25 | 1 | -37/+15 |
| | | | | | | | | | | | Avoid ADD/SUB instruction duplication by reusing the X86ISD::ADD/SUB results. Includes ADD commutation - I tried to include NEG+SUB SUB commutation as well but this causes regressions as we don't have good combine coverage to simplify X86ISD::SUB.
