From a381ef07088ce479610129e37bfef42538f397da Mon Sep 17 00:00:00 2001 From: Jun Nakajima Date: Sat, 17 Dec 2011 19:13:25 -0800 Subject: Changes to existing files to add HAX support HAX (Hardware-based Accelerated eXecution) employes hardware virtualization technology to boost performance of the Android emulator on Mac OS X or Windows hosts. This changeset includes the changes required to the existing files. To pass the compilation, hax.h is added, but CONFIG_HAX is disabled so that no real changes added.
