# The fabric's CPU vector-unit members: the gate's fixed-point arithmetic in

# the processor's own vector extension, certified bit-exact against the CPU
|

# reference's pinned corpus digests.

|
# - avx2 on silicon: the container runner's x86-64 processor;
|
|
# - sve and rvv under the host's user-mode emulator (its binfmt handler), at
|
|
# several vector lengths each: the scalable kernels set their length per
|
|
# pass, and every leg checks the length the member read from the unit is the
|
|
# one the emulator was given, so a leg cannot pass at the wrong length;
|
|
# - the macOS runner, whose processor has no vector extension these kernels
|
|
# use outside streaming mode, finding no member.
|
|
#
|
|
# Silicon for sve and rvv: a processor with them runs the same tests with no
|
|
# emulator declared.
