Mike Frysinger	be0387eed0	sim: hw: rework configure option & device selection The sim-hardware configure option allows builders to select a set of device models to enable. But this seems like unnecessary overkill: the existence of individual device models doesn't affect performance at all as they are only enabled at runtime if the config uses them, and individually these are all <5KB a piece. Stripping off a total of ~50KB from a ~1MB binary doesn't seem useful, and it's extremely unlikely anyone will ever bother. So let's simplify the configure/make logic by turning sim-hardware into a boolean option like many of the other sim options. Any ports that have unique device models will declare them in their Makefile instead of at configure time. This will allow us to (eventually) unify the setting into the common dir.	5 years ago
Mike Frysinger	3eda63f2e4	sim: delete SIM_AC_COMMON macro Now that we've moved all content out to the common file, this is empty and can be deleted it entirely.	5 years ago
Mike Frysinger	df68e12b3b	sim: create header namespace The gdb/callback.h & gdb/remote-sim.h headers have nothing to do with gdb and are really definitions for the libsim API under the sim/ tree. While gdb uses those headers as a client, it's not specific to it. So create a new sim/ namespace and move the headers there.	5 years ago
Mike Frysinger	425b0b1a98	sim: clean up explicit environment build calls This was enabled by default for all targets, but a few ports still include an explicit call. Clean that up, and update the docs.	5 years ago
Mike Frysinger	bd0918c910	sim: nltvals: unify common syscall tables Since libgloss provides a default syscall table for arches, use that to provide the default syscall table for ports. Only the exceptions need to be enumerated now with the common logic as the default.	5 years ago
Mike Frysinger	9d90335212	sim: simplify hardware m4 macro Every port using this sets the 1st arg to yes and the 2nd arg to "". These are the defaults we probably want anyways in order to unify the codebase, so move them to the macro and only allow ports to declare extra hardware models.	5 years ago
Mike Frysinger	ed30adf750	sim: delete unused SIM_EXTRA_LIBDEPS This was last used 15 years ago, so clearly not important enough to keep around. Punt it.	6 years ago
Mike Frysinger	f8069d55c1	sim: delete redundant SIM_EXTRA_ALL We don't need a variable to add a dependency to the "all" target, and having one doesn't really add value. Switch to the target directly for the few ports that actually use this.	6 years ago
Mike Frysinger	136da8cd9c	sim: switch to AC_CONFIG_MACRO_DIRS Rather than hand maintain m4 includes in various autotool files, use AC_CONFIG_MACRO_DIRS to declare the relevant search paths. This simplifies the code, makes it more robust, and cleans out unused logic from configure.	6 years ago
Mike Frysinger	4c0d76b9c4	sim: watchpoints: use common sim_pc_get Few arches implement STATE_WATCHPOINTS()->pc while all of them implement sim_pc_get. Lets switch the sim-watch core for monitoring pc events to the sim_pc_get API so this module works for all ports, and then we can delete this old back channel of snooping in the port's cpu state -- the code needs the pointer to the pc storage so that it can read out bytes and compare them to the watchrange. This also fixes the logic on multi-cpu sims by removing the limitation of only being able to watch CPU0's state.	12 years ago
Mike Frysinger	d4e3adda12	sim: watchpoints: change sizeof_pc to sizeof(sim_cia) Existing ports already have sizeof_pc set to the same size as sim_cia, so simply make that part of the core code. We already assume this in places by way of sim_pc_{get,set}, and this is how it's documented in the sim-base.h API. There is code to allow sims to pick different register word sizes from address sizes, but most ports use the defaults for both (32-bits), and the few that support multiple register sizes never change the address size (so address defaults to register). I can't think of any machine where the register hardware size would be larger than the address word size either. We have ABIs that behave that way (e.g. x32), but the hardware is still equivalent register sized.	12 years ago
Mike Frysinger	5e25901fcc	sim: common: delete configure & Makefile This was mostly orphaned a while back, but left behind so people could still run `make headers`. Merge that one target to the top sim dir and delete all the build logic. This should avoid confusing people further.	6 years ago
Mike Frysinger	68895f7d7e	sim: README-HACKING: clean up stale run references The run.c interface was deleted long ago and everyone moved to nrun.c (which is also the default), so no one needs to declare this anymore.	6 years ago
Mike Frysinger	50df264dae	sim: clean up stale AC_PREREQ refs This was purged from the tree when we upgraded to autoconf-2.69, but a few references in the sim tree were missed.	6 years ago
Mike Frysinger	46f900c065	sim: require a C11 compiler With GDB requiring a C++11 compiler now, this hopefully shouldn't be a big deal. It's been 10 years since C11 came out, so should be plenty of time to upgrade. This will allow us to start cleaning up random header logic and many of our non-standard custom types.	6 years ago
Mike Frysinger	1b393626ce	sim: punt WITH_DEVICES & tconfig.h support 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 `ae7d0cac8c`. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.	11 years ago
Mike Frysinger	306f4178ef	sim: update configure.in->configure.ac docs A few places still refer to the configure.in file; update them.	11 years ago
Mike Frysinger	ae7d0cac8c	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.	12 years ago
