2015-04-15sim: unify sim-cpu usageMike Frysinger1-0/+5
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.
2015-04-13sim: fix the PKGVERSION defineMike Frysinger1-0/+4
This should be SIM, not GDB.
2015-04-06sim: move sim-engine.o/sim-hrw.o to the common listMike Frysinger1-0/+4
This makes these two objects available to all sims by default.
2015-04-02sim: clean up SIM_EXTRA_OBJS referencesMike Frysinger1-0/+4
This variable was deleted in previous commits and is not used anymore. Prune any stray references to it.
2015-04-01sim: update zlib handlingMike Frysinger1-0/+4
With zlib being mandatory, and the updated m4 configs, we need to regen and use the new settings w/bfd to avoid linkage errors.
2015-03-23sim: bfin/msp430: drop run-sim.h includeMike Frysinger1-0/+4
This header is used only with run.o, and both of these use nrun.o.
2015-03-16sim: rename tconfig.in to tconfig.hMike Frysinger1-0/+4
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.
2015-03-14sim: msp430: use common warnings optionsMike Frysinger1-0/+10
This triggers a bunch of new warnings, so fix some of them.
2015-03-14sim: make nrun the default run programMike Frysinger1-0/+4
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.
2015-02-24Fix the detection of illegal memory accesses in the MSP430 simulator.Nick Clifton1-0/+12
* 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.
2014-08-19Fix --diable-shared --enable-plugins build breakageAlan Modra1-0/+4
Directories that don't use libtool need to add -ldl (on most *nix hosts) to provide dlopen for libbfd. config/ * plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to LIBS via AC_SEARCH_LIBS. gdb/ * acinclude.m4 (GDB_AC_CHECK_BFD): Don't add -ldl. * config.in: Regenerate. sim/ppc/ * configure.ac: Invoke AC_PLUGINS. * config.in: Regenerate. and regen lots of configure files.
2014-08-19Replace static variables in the MSP430 simulator with fields in the cpu ↵Nick Clifton1-0/+8
state structure. * msp430-sim.c: Move static hardware multiply support variables from here... * msp430-sim.h (msp430_cpu_state): ... into here ... * msp430-sim.c (get_op, put_op): ... and update references to use the msp430_cpu_state structure.
2014-08-15Regenerate sim configury.Roland McGrath1-0/+5
2014-06-03Fix a small but in the emulation of the MSP430 hardware multiply.Nick Clifton1-0/+7
* msp430-sim.c (get_op): Handle reads of low result register when in MAC mode. (put_op): Copy MAC result into result words. Handle writes to the low result register.
2014-05-12Support 32->64 sign extension in msp430's sign_extDJ Delorie1-0/+5
* msp43-sim.c (sign_ext): Change to "long long" to support sign-extending 32-bit values.
2014-05-08Add support for emulating the MSP430 hardware multiply feature.Nick Clifton1-0/+11
* msp430-sim.c (sim_open): Do not allocate memory over the hardware multiply registers. (get_op): Add support for reads from the hardware multiply registers. (put_op): Add support for writes to the hardware multiply registers. (msp430_step_once): Add support for the RETI instruction used by the CPUX architecture.
2014-03-10sim: msp430: set initial PC to ELF entry if availableMike Frysinger1-0/+5
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.
2014-03-10sim: msp430: fix build time warningsMike Frysinger1-0/+5
This fix is simple: msp430-sim.c: In function 'maybe_perform_syscall': msp430-sim.c:898:10: warning: format '%d' expects argument of type 'int', but argument 5 has type 'long int' [-Wformat] This one we change to use casts like everyone else does in the code base: msp430-sim.c: In function 'msp430_step_once': msp430-sim.c:985:7: warning: passing argument 3 of 'init_disassemble_info' from incompatible pointer type [enabled by default] include/dis-asm.h:368:13: note: expected 'fprintf_ftype' but argument is of type 'int (*)(struct FILE * __restrict__, const char * __restrict__)'
2013-09-23Regenerate sim configure files to pick up support for powerpc64le inAlan Modra1-0/+4
libtool.m4.
2013-06-21 * msp430: New Directory.Nick Clifton1-0/+12
* configure.tgt: Add it. * configure: Regenerate. * gennltvals.sh: Add msp430 support. * nltvals.def: Regenerate. * Makefile.in: New. * aclocal.m4: Generate. * config.in: Generate. * configure.ac: New. * configure: Generate. * msp430-sim.c: New. * msp430-sim.h: New. * sim-main.h: New. * trace.c: New. * trace.h: New.
