From 612536b85f7c68db2cde439f6018f48255a93f95 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Tue, 24 Mar 2020 17:21:51 -0700 Subject: [PATCH] util: Add SCons build files for the aarch64 verson of the m5 utility. These are currently specific to aarch64, but will be expanded to cover all other versions of the utility as well. The intention of these new files is to centralize the build mechanism for the different versions of the utility so that they have consistent features, mechanisms, and targets, and so that new features will automatically be shared by all versions without having to be implemented in each. This also sets up a separate build directory which will keep the source tree clean, and will (with some more development) make it possible to build multiple versions of the m5 utility at the same time without them running into each other.
