The old candidate collection method in the outliner caused some very large regressions in compile time on large tests. For MultiSource/Benchmarks/7zip it caused a 284.07 s or 1156% increase in compile time. On average, using the SingleSource/MultiSource tests, it caused an average increase of 8 seconds in compile time (something like 1000%). This commit replaces that candidate collection method with a new one which only visits each node in the tree once. This reduces the worst compile time increase (still 7zip) to a 0.542 s overhead (22%) and the average compile time increase on SingleSource and MultiSource to 0.018 s (4%). llvm-svn: 298648 |
