From c1c77c4902d5e7c58613d725d09d66a2a743da1c Mon Sep 17 00:00:00 2001 From: Andrew Waterman Date: Tue, 25 Jan 2022 15:13:51 -0800 Subject: Remove tentative purpose for reserved misa.B and misa.J bits This change has no normative effect. What were formerly informally referred to as the B and J extensions are instead going to become multiple smaller and disjoint extensions. Since it appears unlikely that B and J will ultimately have any meaning, simply mark these misa bits as "reserved", rather than "tentatively reserved for X". --- src/machine.tex | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/machine.tex b/src/machine.tex index c7f6fd0..1b26271 100644 --- a/src/machine.tex +++ b/src/machine.tex @@ -116,7 +116,7 @@ The ``X'' bit will be set if there are any non-standard extensions.
