# Builds and runs payload/ava1/test/aead_test.c (RFC 8439 vectors, Monocypher
|
|
# differential, throughput) for `make test-ava1`:
|
|
#
|
|
# - natively: the AVX2 path on an x86-64 host, the portable path elsewhere;
|
|
# - on an arm64 Mac, also as x86-64 under Rosetta 2 (which runs AVX2), so the
|
|
# console's ChaCha20 path is exercised on the machine the payload is
|
|
# developed on. Its MB/s are translated code: indicative only.
|
|
#
|
|
# Without Rosetta 2 the x86-64 run is skipped with a notice, never silently. Set
|
|
# AVA1_X86_IMAGE to a linux/amd64 Docker image that has gcc (or cc) to run it
|
|
# there instead; Docker Desktop on Apple Silicon also translates with Rosetta.
