Subject: lut2mux: handle 1-bit INIT constant in $lut cells.
X-Git-Tag: yosys-0.9~386^2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d1f2cb01dcde4bd8972e28df9e600a4060b77344;p=yosys.git

lut2mux: handle 1-bit INIT constant in $lut cells.

This pass already handles INIT constants shorter than 2^width, but
that was not done for the recursion base case.
