From 005deb0a1683f9ee03a2cf2785dc6a7d7a8f16be Mon Sep 17 00:00:00 2001 From: Andreas Gampe Date: Wed, 24 Jun 2015 16:25:33 -0700 Subject: ART: Set methods to preverified in verify-none Actually mark all methods to be verified, so that the interpreter doesn't do access checks. Speedup is about 2x on a Nexus 6 when booting in verify-none mode.
