From cdf850e9d953f765f600e1ecae61664eab5ae7f1 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 17 Nov 2015 00:19:56 -0800 Subject: [PATCH] sim: always enable modulo memory Having this be a config option doesn't make sense: the code size is pretty much the same (as all the logic is still active), and if it's disabled, the sim throws an error if you try to use it. That means we can't break sims that weren't using it before by enabling it all the time. --- sim/bfin/ChangeLog | 4 ++++ sim/bfin/tconfig.h | 4 ---- sim/common/ChangeLog | 8 ++++++++ sim/common/sim-config.h | 4 ---- sim/common/sim-core.c | 24 +++--------------------- sim/common/sim-core.h | 7 +++---- sim/m68hc11/ChangeLog | 4 ++++ sim/m68hc11/sim-main.h | 1 - sim/mips/ChangeLog | 4 ++++ sim/mips/sim-main.h | 1 - sim/v850/ChangeLog | 4 ++++ sim/v850/sim-main.h | 1 - 12 files changed, 30 insertions(+), 36 deletions(-) diff --git a/sim/bfin/ChangeLog b/sim/bfin/ChangeLog index 4445006346..ac4b774200 100644 --- a/sim/bfin/ChangeLog +++ b/sim/bfin/ChangeLog @@ -1,3 +1,7 @@ +2015-11-17 Mike Frysinger + + * tconfig.h (WITH_MODULO_MEMORY): Delete. + 2015-11-15 Mike Frysinger * Makefile.in (SIM_OBJS): Delete sim-reason.o, sim-reg.o, and diff --git a/sim/bfin/tconfig.h b/sim/bfin/tconfig.h index d28fd8d9f5..a3e6f7bf7c 100644 --- a/sim/bfin/tconfig.h +++ b/sim/bfin/tconfig.h @@ -9,7 +9,3 @@ /* ???
