From 69d2591a829132492662bbfe164fcde5e44ad1c4 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 9 Nov 2012 11:32:52 -0300 Subject: perf machine: Move more methods to machine.[ch] This time out of map.[ch] mostly, just code move plus a buch of 'self' removal, using machine or machines instead.
