* | [SystemZ] Rework IPM sequence generation | Ulrich Weigand | 2018-01-19 | 1 | -0/+73 |
The SystemZ back-end uses a sequence of IPM followed by arithmetic operations to implement the SETCC primitive. This is currently done early during SelectionDAG. This patch moves generating those sequences to much later in SelectionDAG (during PreprocessISelDAG). This doesn't change much in generated code by itself, but it allows further enhancements that will be checked-in as follow-on commits. llvm-svn: 322987 |
