From fe079aa13d6f77f9d7323b58ab24448e73ae6a93 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 8 Jun 2020 10:41:49 -0700 Subject: decodetree: Drop check for less than 2 patterns in a group While it makes little sense for the end product to have a group containing only a single pattern, avoiding this case within an incremental patch set is troublesome. Because this is expected to be a transient condition, do not bother "optimizing" this case, e.g. by folding away the group.
