      "message": "Dex-wide ArenaPool scoping for AOT compilation\n\nThe Arena Pool is a structure that holds memory allocated by the Arena\nAllocator, preventing system allocations and deallocations to occur too often\nduring AOT compilation. Currently, the Arena Pool holds memory it allocates\nduring the whole AOT compilation process. Unfortunately, such a behavior\ngenerates memory usage overhead, which is exacerbated by bigger applications\nsuch as Facebook.\n\nIn this particular app, method size imbalance provokes unnecessary memory\npressure, as one method might require a lot of arena allocations that won\u0027t be\nused in the remaining compilation. Because the compiler memory footprint keeps\nincreasing during AOT compilation, the memory pressure becomes very high.\n\nThe proposed patch is an attempt to find a tradeoff between allocations /\ndeallocations time overhead, and the aforementioned memory pressure overhead\nresulting of the allocations being held by the Arena Pool. The patch adds a\nfeature freeing up all memory allocated in the Arena Pool after each dex file\nis done compiling.\n\nWe have measured no significant AOT compile-time overhead with the patch\n(\u003c0.3%), because the selected dex-file granularity is coarse enough. In the\nmeantime, it provides significant memory footprint improvements. The impact is\nespecially big with Facebook, because this app has a few methods generating\nhuge memory footprint peaks (peak native heap footprint goes down 34%).\n\nChange-Id: I27e867e6a20b8a6c28a82cb83140941a8c2b5847\nSigned-off-by: Jean-Philippe Halimi \u003cjean-philippe.halimi@intel.com\u003e\n"
