* | [MachinePipeliner] Fix risky iterator usage R++, --R | Jinsong Ji | 2019-06-25 | 1 | -1/+1 |
| | | | | | | | | | | | | | When we calculate MII, we use two loops, one with iterator R++ to check whether we can reserve the resource, then --R to move back the iterator to do reservation. This is risky, as R++, --R may not point to the same element at all. The can cause wrong MII. Differential Revision: https://reviews.llvm.org/D63536 llvm-svn: 364353 | ||||
