From a1222b75350a098e70106bf95d4e6a962c37f373 Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Fri, 22 Jan 2021 11:13:32 -0500 Subject: [PATCH] cmd/link: add debug print in deadcode This matches the prints that deadcode prints later as the algorithm progresses under -v=2. It helps to see the initial conditions with -v=2 as well.
