From dc151b2346bb8a4fdeed0c06e54c2fca21d59b5d Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Thu, 15 Oct 2015 18:02:30 +0100 Subject: Optimizing: Determine invoke-static/-direct dispatch early. Determine the dispatch type of invoke-static/-direct in a special pass right after the type inference. This allows the inliner to pass the "needs dex cache" check and inline more. It also allows the code generator to avoid requesting a register location for the ArtMethod* for kDexCachePcRelative and direct methods. The supported dispatch check handles also situations that the CompilerDriver currently doesn't allow. The cleanup of the CompilerDriver and required changes to Quick will come in a separate change.
