From 69d310e0317e2fce97bf8c9c133c5c2c0332e61d Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Mon, 9 Oct 2017 14:12:23 +0100 Subject: Use ScopedArenaAllocator for building HGraph. Memory needed to compile the two most expensive methods for aosp_angler-userdebug boot image: BatteryStats.dumpCheckinLocked() : 21.1MiB -> 20.2MiB BatteryStats.dumpLocked(): 42.0MiB -> 40.3MiB This is because all the memory previously used by the graph builder is reused by later passes. And finish the "arena"->"allocator" renaming; make renamed allocator pointers that are members of classes const when appropriate (and make a few more members around them const).
