Member Data Documentation

bool native::arm_capabilities::raw_observations::ebf16 = false

OS advertises enhanced BF16 behavior, usable when the caller sets FPCR.EBF. Also exposed as arm_feature::ebf16; NEON_BF16 does not require it.

isa<arm> native::arm_capabilities::raw_observations::extra_observed {}

Additional independent instruction-feature queries. A feature must occur in both sets; failed queries never authorize it.
