# "Comprehensive" set of tests that nothing is critically broken by the m1 | |
# branch. | |
# | |
# The claim is that: | |
# x86_64-darwin bootstrap tools can be recreated natively | |
# aarch64-darwin bootstrap tools can be cross compiled by x86_64-darwin | |
# | |
# This test suite is probably best run on an aarch64-darwin computer with | |
# x86_64-darwin remote builders. If run with rosetta, there's a chance that | |
# platform mismatches will be unnoticed. |
