From 85c0f2ac03417f5125bc2ff1dab8109859c67d5c Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Thu, 2 Feb 2017 16:42:38 +0000 Subject: Revert^2 "Hash-based dex cache type array." The reason for the revert was fixed by https://android-review.googlesource.com/332666 . We now enable clearing dex cache types in test 155 from that CL. Also avoid an unnecessary store in LookupResolvedTypes() and prevent verifier from messing up the dex cache types. Test: m test-art-host Bug: 34839984 Bug: 30627598 Bug: 34659969 This reverts commit d16363a93053de0f32252c7897d839a46aff14ae.
