pub fn ffn_gateup_fused() -> boolExpand description
Whether the compiled target arms the fused gate+up decode GEMM.
The target declares it (kernels/<hw>/HARDWARE.toml [defaults] ffn_gateup_fused); ATLAS_FFN_GATEUP_FUSED overrides it under the
2026-09-11 grammar, so =0/=off/=false turn it off and anything else
turns it on. There is no ATLAS_NO_* legacy spelling: the lever is new, so
no script predates the grammar and none can be surprised by it.
