Hi all,
Just wanted to share a little build script I wrote for gem5. It presents a
table with all the architectures and optimization levels. You can navigate
and select which versions you want to build and then it will build all of
those binaries for you. Your previous selections are saved in a little db
file, so you can just call the script and hit "enter" on subsequent runs.
It pulls the architecture list from the build_opts/ directory, so it will
stay up to date.
Run inside the gem5 base dir. Arrow keys to navigate, space_bar to toggle a
selection, enter_key to proceed, "q" to exit and discard changes.
Cheers!
