* | Add synthesize uses at back edge. | Nicolas Geoffray | 2015-04-29 | 3 | -0/+133 |
This reduces the cost of linearizing the graph (hence removing the notion of back edge). Since linear scan allocates/spills registers based on next use, adding a use at a back edge ensures we do count for loop uses. Change-Id: Idaa882cb120edbdd08ca6bff142d326a8245bd14 |
