2016-01-03sim: drop host endian configure optionMike Frysinger3-261/+232
The --enable-sim-hostendian flag was purely so people had an escape route for when cross-compiling. This is because historically, AC_C_BIGENDIAN did not work in those cases. That was fixed a while ago though, so we can require that macro everywhere now and simplify a good bit of code.
2016-01-03sim: convert to bfd_endianMike Frysinger4-21/+26
Rather than re-invent endian defines, as well as maintain our own list of OS & arch-specific includes, punt all that logic in favor of the bfd ones already set up and maintained elsewhere. We already rely on the bfd library, so leveraging the endian aspect should be fine.
2016-01-02sim: cris: use standard output helpersMike Frysinger2-35/+14
The sim-io module provides output helpers, so no need to define local ones anymore.
2016-01-02sim: delete dead current_state globalsMike Frysinger2-8/+5
The global current_state handle to the current simulator state is a design idea that was half implemented, but never really cleaned up. The point was to have a global variable pointing to the state so that funcs could more quickly & easily access the state anywhere. We've instead moved in the direction of passing state around everywhere and don't have any intention of moving back. I also can't find any references to gdb using this variable, or to cgen related "dump_regs" functions, both of which were used in the comments related to this code.

2015-12-30sim: cris/m68hc11: move default endian/alignment to configureMike Frysinger4-8/+57
2015-12-27sim: unify sim-hloadMike Frysinger2-46/+4
Pretty much all targets are using this module already, so add it to the common list of objects. The only oddball out here is cris and that's because it supports loading via an offset for all the phdrs. We drop support for that.
2015-12-26sim: punt WITH_DEVICES & tconfig.h supportMike Frysinger4-7/+8
No arch is using this anymore, and we want all new ports using the hardware framework instead. Punt WITH_DEVICES and the two callbacks device_io_{read,write}_buffer. We can also punt the tconfig.h file as no port is using it anymore. This fixes in-tree builds that get confused by picking up the wrong one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.
2015-12-26sim: cris: do not pass cpu when writing memory during initMike Frysinger2-5/+10
The point of passing down the cpu to core reads/writes is to signal which cpu is making the access. For system accesses (such as internal memory initialization), passing the cpu down doesn't make sense, and in the case of early init like cris, can cause crashes. Since the cpu isn't fully set up at this point, if the core code tries to access some fields (like the PC reg), it'll crash. While cris shouldn't be doing this setup here (it should be in the inferior stage), we'll deal with that later.
2015-12-26sim: standardize sim_create_inferior handling of argv a bit moreMike Frysinger2-5/+14
For targets that process argv in sim_create_inferior, improve the code: - provide more details in the comment - make the check for when to re-init more robust - clean out legacy sim_copy_argv code This will be cleaned up more in the future when we have a common inferior creation function, but at least help new ports get it right until then.
2015-12-25sim: cris: migrate from WITH_DEVICES to WITH_HWMike Frysinger8-125/+108
The cris port was using the device framework to handle two addresses when the --cris-900000xx flag was specified. That can be implemented using the newer hardware framework instead which allows us to drop the device logic entirely, as well as delete the tconfig.h file. Basically we create a new cris_900000xx device model and move the read logic out of devices.c and into that. The rest of the devices logic was callback to the hardware framework already.
2015-12-25sim: cris: clean up rvdummy a bitMike Frysinger2-2/+6
This fixes a few warnings when compiling the rvdummy tool.
2015-12-25sim: sim-model: build for everyoneMike Frysinger3-3/+5
Rather than include this for some targets, set it up so we can build it all the time via the common code. This makes it easier for targets to opt into it when they're ready, increases build coverage, and allows us to centralize much of the logic. We also get to delete tconfig.h from two more targets -- they were setting WITH_DEVICES to 0 which has the same behavior as not defining it at all. While the SIM_HAVE_MODEL knob is gone, we now have WITH_MODEL_P, but it is only used by the common sim-model code. We use it to declare dummy model lists when the arch hasn't created its own.
2015-12-25sim: move MACH/MODEL types into SIM_xxx namespaceMike Frysinger5-9/+17
The "MACH" and "MODEL" names are a bit generic and collide with symbols used by other sections of code (like h8300's opcodes). Since these are sim-specific types, they really should have a "SIM_" prefix.
2015-12-25sim: move WITH_SCACHE_PBB to sim-main.hMike Frysinger3-5/+10
This helps us break up tconfig.h more. Any file using this define should be pulling in sim-main.h already, so things should continue working.
2015-12-25sim: device_error: puntMike Frysinger2-8/+4
Only four targets implement this function, and three of them do nothing. The 4th merely calls abort. Since calls to this function are followed by calls to sim_hw_abort or sim_io_error, this is largely useless. In the two places where we don't, replace the call with sim_engine_abort. We want to kill off the WITH_DEVICES logic in favor of WITH_HW, so this is a good first step.
2015-12-24sim: make LMA loading the default for all targetsMike Frysinger2-3/+4
Most targets already default to loading code via their LMA, but for a few, this means the default changes from loading VMA to LMA. It's better to have the different targets be consistent, and allows some code clean up.
2015-12-24sim: cris: move option install to sim_openMike Frysinger2-15/+7
We've moved custom option install for other targets to sim_open, so update cris too. It's the last one using MODULE_LIST, so we can drop that from the common code too.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger2-2/+6
Now that all arches (for the most part) have moved over, move sim-stop.o, sim-reason.o, and sim-reg.o to the common object list and out of all the arch ports.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger2-7/+4
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.
2015-06-23sim: use AS_HELP_STRING everywhereMike Frysinger2-15/+31
This helps standardize the configure --help output.
2015-06-17sim: syscall: unify memory helpersMike Frysinger2-30/+10
Almost every port implements these two callbacks in the same way, so unify them in the common layer.
2015-06-17sim: callback: add human readable strings for debugging to mapsMike Frysinger2-161/+166
When tracing, we often want to display the human readable name for the various syscall/errno values. Rather than make each target duplicate the lookup, extend the existing maps to include the string directly, and add helper functions to look up the constants. While most targets are autogenerated (from libgloss), the bfin/cris targets have custom maps for the Linux ABI which need to be updated by hand.
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: cgen: namespace custom trace functionsMike Frysinger6-2695/+2705
The cgen code declares some macros/funcs using the trace_xxx prefix, but the code isn't generic and only works with cgen targets. This is blocking the creation of new common trace functions. Let's blindly add cgen_xxx prefixes to all these symbols. Some already use this convention to avoid conflicts, so it makes sense to align them. In the future we might want to move some to the common trace core, but one thing at a time.
2015-04-18sim: clean up duplicate sim-engine hooksMike Frysinger2-11/+4
Now that we've unified sim-cpu, we can delete the duplicate sim-engine hooks -- these targets defined these only because they didn't fully implement the sim-cpu callbacks.
2015-04-18sim: trim old USING_SIM_BASE_H defineMike Frysinger2-2/+4
This doesn't appear to have been used since 1998, but wasn't cleaned up since. So much for being "quick" ;).
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 Frysinger2-3/+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 Frysinger4-5/+8
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 Frysinger3-6/+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.
2015-04-15sim: cris/frv/h8300/iq2000/lm32/m32r/sh64: standardize cpu stateMike Frysinger2-2/+11
This sets up the sim_state structure and the cpu member to match what we do in most other sims, and what the common code suggests. This is a step to unifying on the sim-cpu.o object.
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/+5
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.
2015-03-24sim: fix sim-hardware configure optionMike Frysinger2-6/+6
The current default handling for the --enable-sim-hardware option ends up forcing the value to whatever is set as the first argument when calling the macro (by virtue of how autoconf works). Relocate the setup code to the 4th parameter of the AC_ARG_ENABLE macro to fix it. This was caused by the simplification work in 1517bd274290e06af498ef7e49. Reported-by: Hans-Peter Nilsson <hans-peter.nilsson@axis.com>
2015-03-23sim: drop support for requiring hw supportMike Frysinger2-10/+9
Since no sim is using the "always" option to SIM_AC_OPTION_HARDWARE, and we don't want to require hw support to always be enabled, drop the option. This leads to a slight simplification in the macro too as we can collapse the sim_hw_p variable.
2015-03-23sim: cris: delete unused CONFIG_DEVICESMike Frysinger2-3/+5
Looks like unused copy & paste from other sim ports. Drop it.
2015-03-23sim: dv-sockser: move build to common dirMike Frysinger2-6/+10
If dv-sockser is available, lets add it to the common SIM_HW_OBJS variable so it is always included automatically. Now ports do not have to shoe horn it in directly themselves. It does mean it will be compiled for targets that don't explicitly use it, but that's really what we want anyways.
2015-03-16sim: rename tconfig.in to tconfig.hMike Frysinger6-22/+23
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.
2015-03-15sim: dv-sockser: push module init prototype downMike Frysinger2-12/+6
Pull out the duplicated dv_sockser_install prototype from the tconfig.in files and put it in the one place it gets used -- sim-module.c. This is still arguably incorrect, but it's better than the status quo where the tconfig.in has to include header files and duplicate the dv-sockser func. The tconfig header is meant to be simple and contain a target defines.
2015-03-14sim: make nrun the default run programMike Frysinger2-1/+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.

2014-12-03callback.h:struct host_callback_struct compilation error on Windows hosts.Joel Brobecker2-1/+6
On Windows, a recent gnulib update imported the lstat module, and this caused a remote-sim.c build failure in struct host_callback_struct: In file included from /[...]/gdb/remote-sim.c:34:0: /[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64' int (*lstat) (host_callback *, const char *, struct stat *); ^ What happens it that gnulib's stat.h makes the following defines: /* Large File Support on native Windows. */ #if 1 # define stat _stati64 #endif and then: #if 1 # if ! 0 /* mingw does not support symlinks, therefore it does not have lstat. But without links, stat does just fine. */ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define lstat stat # endif So, the following fields in struct host_callback_struct... int (*stat) (host_callback *, const char *, struct stat *); int (*fstat) (host_callback *, int, struct stat *); int (*lstat) (host_callback *, const char *, struct stat *); ... get translated to... int (*_stati64) (host_callback *, const char *, struct _stati64 *); int (*_fstati64) (host_callback *, int, struct _stati64 *); int (*_stati64) (host_callback *, const char *, struct _stati64 *); ... which causes two fields to have the same name.
