native-image -march=list
------------------------

(Annoted list -- "Y" is a preset I think would work for Deck-targetted
builds, "N" is for those that won't.  For flags with a slash: first bit
is what native-image says, second bit is what I think they're actually
reported as in /proc/cpuinfo)

On AMD64, the following machine types are available:

Y?  'native' (detected on my desktop CPU)
      CPU features: cx8 + cmov + fxsr + mmx + amd_3dnow_prefetch/3dnowprefetch + sse + sse2 + sse3/pni + ssse3 + sse4a + sse4_1 + sse4_2 + popcnt + lzcnt/abm + tsc + tscinv_bit(?) + avx + aes + clmul/pclmulqdq + bmi1 + fma + vzeroupper(?) + flush/clflush
      (looks like the Deck might actually have all these, though I have no idea where "tscinv_bit"
      and "vzeroupper" come from on my own CPU; nothing like that is listed in my flags below)

Y   'x86-64'
      CPU features: cx8 + cmov + fxsr + mmx + sse + sse2

Y   'x86-64-v1'
      CPU features: all of 'x86-64'

Y   'x86-64-v2'
      CPU features: all of 'x86-64-v1' + sse3/pni + ssse3 + sse4_1 + sse4_2 + popcnt

Y   'x86-64-v3'
      CPU features: all of 'x86-64-v2' + lzcnt/abm + avx + avx2 + bmi1 + bmi2 + fma

N   'x86-64-v4'
      CPU features: all of 'x86-64-v3' + avx512f + avx512dq + avx512cd + avx512bw + avx512vl
      (missing basically all the extras)

Y   'compatibility'
      CPU features: all of 'x86-64'

Y   'haswell'
      CPU features: all of 'x86-64' + sse3/pni + ssse3 + sse4_1 + sse4_2 + popcnt + lzcnt/abm + avx + avx2 + aes + clmul/pclmulqdq + bmi1 + bmi2 + fma

Y   'skylake'
      CPU features: all of 'haswell' + amd_3dnow_prefetch/3dnowprefetch + adx + flushopt/clflushopt

N   'skylake-avx512'
      CPU features: all of 'skylake' + avx512f + avx512dq + avx512cd + avx512bw + avx512vl + clwb
      (missing all the avx512* ones)
