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.

2015-04-17 Mike Frysinger <vapier@gentoo.org>
* sim-main.h (CIA_GET, CIA_SET): Delete.
sim: unify sim-cpu usage Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the cpu state is multicore, and the STATE_CPU defines match, we can move it all to the common code.
2015-04-15 06:13:23 +00:00
2015-04-15 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete sim-cpu.o.
* sim-main.h (STATE_CPU): Delete.
sim: fix the PKGVERSION define This should be SIM, not GDB.
2015-04-13 06:38:57 +00:00
2015-04-13 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: move sim-engine.o/sim-hrw.o to the common list This makes these two objects available to all sims by default.
2015-04-07 03:40:00 +00:00
2015-04-06 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete sim-engine.o and sim-hrw.o.
sim: clean up SIM_EXTRA_OBJS references This variable was deleted in previous commits and is not used anymore. Prune any stray references to it.
2015-04-01 06:34:00 +00:00
2015-04-01 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete $(SIM_EXTRA_OBJS).
sim: update zlib handling With zlib being mandatory, and the updated m4 configs, we need to regen and use the new settings w/bfd to avoid linkage errors.
2015-04-01 03:32:49 +00:00
2015-03-31 Mike Frysinger <vapier@gentoo.org>
* config.in, configure: Regenerate.
sim: bfin/msp430: drop run-sim.h include This header is used only with run.o, and both of these use nrun.o.
2015-03-23 04:08:25 +00:00
2015-03-23 Mike Frysinger <vapier@gentoo.org>
* sim-main.h: Delete run-sim.h include.
sim: rename tconfig.in to tconfig.h Rather than manually include tconfig.h when we think we'll need it (which is error prone as it can define symbols we expect from config.h), have it be included directly by config.h. Since we know we have to include that header everywhere already, this will make sure tconfig.h isn't missed. It should also be fine as tconfig.h is supposed to be simple and only set up a few core defines for the target. This allows us to stop symlinking it in place all the time and just use it straight out of the respective source directory.

2015-03-16 Mike Frysinger <vapier@gentoo.org>
* config.in, configure: Regenerate.
sim: msp430: use common warnings options This triggers a bunch of new warnings, so fix some of them.
2014-03-08 05:56:53 +00:00
2015-03-14 Mike Frysinger <vapier@gentoo.org>
* aclocal.m4, configure: Regenerate.
* configure.ac: Call the common inline & warning macros.
* msp430-sim.c: Include unistd.h & trace.h.
* trace.c: Include trace.h.
(load_file_and_line): Move FILE* decl to top of scope.
* trace.h (msp430_get_current_source_location): Adjust prototype to
match the function definition.
sim: make nrun the default run program We want people to stop using the run.c frontend, but it's hard to notice when it's still set as the default. Lets flip things so nrun.c is the default, and users of run.c will get an error by default. We turn that error into a warning for existing sims so we don't break them -- this is mostly meant for people starting new ports.

2015-03-14 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_RUN_OBJS): Delete.
Fix the detection of illegal memory accesses in the MSP430 simulator. * msp430-sim.c (sim_open): Allocate memory regions matching those declared in the libgloss/msp430 linker scripts. Allow sim_load_file to fail. (get_op): Test the correct address bit when checking for out of range addresses. Include the address in the error message when an illegal access to the hardware multiplier is detected. (put_op): Test the correct address bit when checking for out of range addresses.

sim: msp430: set initial PC to ELF entry if available If we want to run a simple ELF, the reset vector isn't set up, so starting at address 0 doesn't make sense. Use the ELF's entry point instead.
