From 68a5fefa90f03fdf5a238ac85c9439c6b03eae96 Mon Sep 17 00:00:00 2001 From: Nicolas Geoffray Date: Tue, 18 Feb 2014 16:43:35 +0000 Subject: Initial check-in of an optimizing compiler. The classes and the names are very much inspired by V8/Dart. It currently only supports the RETURN_VOID dex instruction, and there is a pretty printer to check if the building of the graph is correct.
