2015-11-15sim: sim-close: unify sim_close logicMike Frysinger3-3/+11
Other than the nice advantage of all sims having to declare one fewer common function, this also fixes leakage in pretty much every sim. Many were not freeing any resources, and a few were inconsistent as to the ones they did. Now we have a single module that takes care of all the logic for us. Most of the non-cgen based ones could be deleted outright. The cgen ones required adding a callback to the arch-specific cleanup func. The few that still have close callbacks are to manage their internal state. We do not convert erc32, m32c, ppc, rl78, or rx as they do not use the common sim core.
2015-06-24sim: trace: add a basic cpu register classMike Frysinger2-2/+7
The bfin/msp430 ports already had trace logic set up for reading/writing cpu registers, albeit using different unrelated levels (core & vpu). Add a proper register class for these and for other ports.
2015-06-23sim: use AS_HELP_STRING everywhereMike Frysinger2-11/+23
This helps standardize the configure --help output.
2015-06-17sim: syscall: add common sim_syscall helpersMike Frysinger2-56/+13
Many ports have the same sim syscall logic, so add some helpers to handle all the common details. The arches still have to deal with the unpacking and packing of the syscall arguments, but the rest of the sim<->callback glue is now shared.
2015-06-17sim: syscall: unify memory helpersMike Frysinger2-22/+10
Almost every port implements these two callbacks in the same way, so unify them in the common layer.
2015-06-12sim: update configure.in->configure.ac docsMike Frysinger2-1/+5
A few places still refer to the configure.in file; update them.
2015-06-12sim: drop -DTRACE from configureMike Frysinger2-3/+7
No code uses this anymore and the symbol conflicts with the new TRACE helper. Punt it from configure.
2015-06-12sim: msp430: use new common trace print helpersMike Frysinger2-109/+69
Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx". The output is the same, but the code is nicer to read.
2015-06-11sim: msp430: delete unused trace macrosMike Frysinger2-48/+6
These macros were copied from the Blackfin port but never used, so delete them as part of the trace unification work.
2015-04-18sim: unify SIM_CPU definitionMike Frysinger2-3/+4
Since every target typedefs this the same way, move it to the common code. We have to leave Blackfin behind here for now because of inter-dependencies on types and headers: sim-base.h includes sim-model.h which needs types in machs.h which needs types in bfim-sim.h which needs SIM_CPU.
2015-04-18sim: unify sim_cia definitionMike Frysinger2-2/+4
Almost every target defines sim_cia the same way -- either using the address_word type directly, or a type of equivalent size. The only odd one out is sh64 (who has 32bit address_word and 64bit cia), and even that case doesn't seem to make sense. We'll put off clean up though of sh64 and at least set up a sensible default for everyone.
2015-04-17sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}Mike Frysinger2-3/+4
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.
2015-04-15sim: unify sim-cpu usageMike Frysinger3-7/+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 Frysinger2-2/+6
This should be SIM, not GDB.
2015-04-06sim: move sim-engine.o/sim-hrw.o to the common listMike Frysinger2-2/+4
This makes these two objects available to all sims by default.

2015-04-01sim: update zlib handlingMike Frysinger3-84/+17
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 Frysinger2-1/+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 Frysinger3-10/+10
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 Frysinger7-15/+186
This triggers a bunch of new warnings, so fix some of them.
2015-03-14sim: make nrun the default run programMike Frysinger2-2/+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.

2014-03-10sim: msp430: set initial PC to ELF entry if availableMike Frysinger2-1/+11
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 Frysinger2-2/+7
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__)'
