cgen : ChangeLog decode.scm utils-sim.scm utils.scm
Log message:
* major sim decoder improvement
* minor diagnostic tweaks
2000-11-10 Frank Ch. 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.
