This commit fixes many problems which were resulting in these tests not executing correctly. However, the m5thread tests are still failing with an `fatal:syscall set_tid_address (#166) unimplemented` error, recorded here: https://gem5.atlassian.net/browse/GEM5-747. The tests have been removed from .testignore as part of our goal of removing all tests from the .testignore file: https://gem5.atlassian.net/browse/GEM5-361 Change-Id: I287d1e126963114a791d7f3aa563a037a89b2cb7 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/32916 Reviewed-by: Jason Lowe-Power <power.jg@gmail.com> Maintainer: Jason Lowe-Power <power.jg@gmail.com> Tested-by: kokoro <noreply+kokoro@google.com>
