From bf9cd7ba2118a75f5aa9b56241c4d5fa00dedeb8 Mon Sep 17 00:00:00 2001 From: Roland Levillain Date: Tue, 30 Sep 2014 16:15:14 +0100 Subject: Introduce a class to implement optimization passes. - Add art::HOptimization. - Rename art::ConstantPropagation to art::HConstantFolding in compiler/optimizing/constant_folding.h to avoid name clashes with a class of the same name in compiler/dex/post_opt_passes.h. - Rename art::DeadCodeElimination to art::HDeadCodeElimination for consistency reasons. - Have art::HDeadCodeElimination and art::HConstantFolding derive from art::HOptimization. - Start to use these optimizations in art:OptimizingCompiler::TryCompile.
