From 034685f9ce92cf6dfb6656745365b6a5904a8e84 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 16 Apr 2015 02:11:12 -0400 Subject: sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET} The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET} except the latter adds a layer of indirection via the sim state. This lets models set up different functions at runtime and doesn't reach so directly into the arch-specific cpu state. It also doesn't make sense to have two sets of macros that do exactly the same thing, so lets standardize on the one that gets us more. --- sim/mcore/ChangeLog | 8 ++++++++ sim/mcore/interp.c | 8 ++++---- sim/mcore/sim-main.h | 3 --- 3 files changed, 12 insertions(+), 7 deletions(-) (limited to 'sim/mcore') diff --git a/sim/mcore/ChangeLog b/sim/mcore/ChangeLog index a00954c..89f17d8 100644 --- a/sim/mcore/ChangeLog +++ b/sim/mcore/ChangeLog @@ -1,3 +1,11 @@ +2015-04-17 Mike Frysinger + + * interp.c (set_initial_gprs): Change CIA_SET to CPU_PC_SET. + (sim_resume): Change CIA_GET to CPU_PC_GET and CIA_SET to + CPU_PC_SET. + (sim_create_inferior): Change CIA_SET to CPU_PC_SET. + * sim-main.h (CIA_GET, CIA_SET): Delete. + 2015-04-16 Mike Frysinger * interp.c (mcore_pc_get, mcore_pc_set): New functions. diff --git a/sim/mcore/interp.c b/sim/mcore/interp.c index fc1131b..54d628c 100644 --- a/sim/mcore/interp.c +++ b/sim/mcore/interp.c @@ -397,7 +397,7 @@ set_initial_gprs (SIM_CPU *scpu) init_pointers (); /* Set up machine just out of reset. */ - CIA_SET (scpu, 0); + CPU_PC_SET (scpu, 0); cpu.sr = 0; memsize = cpu.asregs.msize / (1024 * 1024); @@ -716,7 +716,7 @@ sim_resume (SIM_DESC sd, int step, int siggnal) word WLhash; cpu.asregs.exception = step ?
