From b8fb721b813785e19591fcc39354dfd8615b99d3 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 8 Oct 2019 18:46:01 +1100 Subject: [PATCH] Consolidate logical instructions Consolidate and/andc/nand, or/orc/nor and xor/eqv, using a common invert on the input and output. This saves us about 200 LUTs.
