From 35831e8bfa1c0944d4c978d99c4c5b9577945170 Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Fri, 11 Sep 2015 11:59:18 +0100 Subject: Reduce memory used by CompiledMethods. Use LengthPrefixedArray<>s instead of SwapVector<>s to store CompiledMethod data and get rid of the unnecessary members of CompiledMethod to reduce dex2oat memory usage. Refactor the deduplication from CompilerDriver to a new class. Use HashSet<> instead of std::set<> for the DedupeSet<> to further decrease the memory usage and improve performance. This reduces the dex2oat memory usage when compiling boot image on Nexus 5 (with Optimizing, -j1) by ~6.75MiB (5%). This also reduces the compile time by ~2.2% (~1.6% dex2oat time; with Optimizing, without -j).
