[gem5-dev] Change in gem5/gem5[develop]: util: Add SCons build files for the aarch64 verson of the m5 utility.
Gabe Black has submitted this change. ( https://gem5-review.googlesource.com/c/public/gem5/+/27213 ) Change subject: util: Add SCons build files for the aarch64 verson of the m5 utility. .. 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.
