Eigler <fche@redhat.com> * decode.scm (-distinguishing-bit-population): Significantly improve popularity heuristic. Renamed from (-mask-bit-population): Gone. (-population-above-threshold): Sort new bit numbers in order of popularity. (-population-top-few): Allow up to three more bits to be selected than requested. Correct selection order to prefer better bits. Correct bug in fewer-than-requested case. Keep threshold as floating-point. (decode-best-get-bits): Pass also the insn-values. * utils-sim.scm (-gen-decoder-switch): Add comment suggesting a future optimization. * utils.scm (message): Format nested lists better.
