Where possible the gem5 tests have been updated to use the build/ALL/gem5.opt compilation. If a quick test requied a specific a ISA/protocol compilation they were moved to the long/nightly set. This means all the quick/kokoro tests are run with the build/ALL/gem5.opt compilation. The learning_gem5 tests have been updated to use ALL/gem5.opt. The equivilant examples on the website have been updated via: https://gem5-review.googlesource.com/c/public/gem5-website/+/63336 Change-Id: I533689ad6848233867bdba9e9a43bb5840ed65c7 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/63374 Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Maintainer: Bobby Bruce <bbruce@ucdavis.edu>
