From 8852d02874735b231b0a0e36c767423542212f49 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 6 May 2021 23:51:10 -0400 Subject: [PATCH] sim: m68hc11: warn when emul_write fails Not sure what we should do here when this fails, so just emit a warning for now to satisfy unused result compiler warnings. We can see if any users actually notice here. --- sim/m68hc11/ChangeLog | 5 +++++ sim/m68hc11/emulos.c | 7 +++++-- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/sim/m68hc11/ChangeLog b/sim/m68hc11/ChangeLog index 6fd984dfa99..48b54b45dea 100644 --- a/sim/m68hc11/ChangeLog +++ b/sim/m68hc11/ChangeLog @@ -1,3 +1,8 @@ +2021-05-06 Mike Frysinger + + * emulos.c: Include errno.h & stdio.h. + (emul_write): Print a warning when the write fails. + 2021-05-04 Mike Frysinger * dv-m68hc11.c (struct m68hc11cpu): Change attach_size to unsigned int. diff --git a/sim/m68hc11/emulos.c b/sim/m68hc11/emulos.c index 916364f306c..247e66871cf 100644 --- a/sim/m68hc11/emulos.c +++ b/sim/m68hc11/emulos.c @@ -23,6 +23,8 @@ along with this program.
