An application writer can't use:
# include {x86 spec}"
to get these values ... if applications need them to find out if AMX is present,
and to enable it, then they need an API.
Maybe your example code should just be a library routine? So application writers
can just do:
if (!intel_amx_enable()) {
error message, or fall back to non-AMX implementation
}
without having to worry about those #defines.
