# Regarding `skylake` as inferior of `znver1`, there are reports of
# successful usage by Gentoo users and Phoronix benchmarking of different
# `-march` targets.
#
# The GCC documentation on extensions used and wikichip documentation
# regarding supperted extensions on znver1 and skylake was used to create
# this partial order.
#
# Note:
#
# - The succesors of `skylake` (`cannonlake`, `icelake`, etc) use `avx512`
# which no current AMD Zen michroarch support.
# - `znver1` uses `ABM`, `CLZERO`, `CX16`, `MWAITX`, and `SSE4A` which no
# current Intel microarch support.
