The 27x18 rule carried B_MINWIDTH=13, so any product whose narrower operand was below 13 (e.g. 27x4, 4x13) was rejected even though it fits one MULTALU27X18 tile, and decomposed onto MULT12X12 partials instead. Drop the floor to 2 so the rule blocks only degenerate Nx1 multiplies, matching the rest of the tree. Adds a 4x13 regression case. |
