The original code to keep track of the minimum and maximum indices of allocated 32-bit primary regions was sketchy at best. `MinRegionIndex` & `MaxRegionIndex` were shared between all size classes, and could (theoretically) have been updated concurrently. This didn't materialize anywhere I could see, but still it's not proper. This changes those min/max indices by making them class specific rather than global: classes are locked when growing, so there is no concurrency there. This also allows to simplify some of the 32-bit release code, that now doesn't have to go through all the regions to get the proper min/max. Iterate and unmap will no longer have access to the global min/max, but they aren't used as much so this is fine. Differential Revision: https://reviews.llvm.org/D91106 |
