From 8a492f46cf91216277a478a7b0cb81d8c8dd9073 Mon Sep 17 00:00:00 2001 From: Jan Bobek Date: Thu, 23 May 2019 16:44:04 -0400 Subject: risu_i386: remove old unused code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The code being removed is a remnant of the past implementation; it has since been replaced by its more powerful, architecture-independent counterpart in reginfo.c.
