sim: move MACH/MODEL types into SIM_xxx namespace 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.

2015-12-25 Mike Frysinger <vapier@gentoo.org>
* machs.c: Rename MACH to SIM_MACH, MACH_IMP_PROPERTIES to
SIM_MACH_IMP_PROPERTIES, and MODEL to SIM_MODEL.
sim: device_error: punt 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.

* devices.c (device_error): Delete.
sim: make LMA loading the default for all targets 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.

* tconfig.h (SIM_HANDLES_LMA): Delete.
sim: always enable modulo memory Having this be a config option doesn't make sense: the code size is pretty much the same (as all the logic is still active), and if it's disabled, the sim throws an error if you try to use it. That means we can't break sims that weren't using it before by enabling it all the time.

* Makefile.in (SIM_OBJS): Delete sim-reason.o, sim-reg.o, and
sim-stop.o.
sim: sim-close: unify sim_close logic 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.

sim: callback: add human readable strings for debugging to maps 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.

We'll put off clean up though of sh64 and at least set up a sensible default for everyone.

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.

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.

sim: rewrite SIM_AC_OPTION_HARDWARE a bit to simplify things There's no need to put the majority of the logic into the 3rd arg of the AC_ARG_ENABLE. Coupled with the lack of indentation, it makes it hard to follow, error prone to update, and duplicates code (with the 4th arg). So pull the logic out of the 3rd arg and outside of the AC_ARG_ENABLE macro. This allows us to gut the 4th arg entirely, merge with the code that followed the macro, and fix bugs related to the new dv-sockser in the process. Hopefully building the various sims with the default sim-hardware settings, as well as with explicit --{dis,en}able-sim-hardware flags, should all just work now.

sim: bfin: fix M_IH saturation size This reverts the previous commit and does it right. This change got lost in the shuffle of patches I have pending. Basically the logic is to change the 32bit saturation (and then masked to 16bits) to a proper 16bit saturation.

sim: bfin: fix sign extension in dsp insns with MM flag After testing the hardware with all the different dsp flags, the MM flag triggers sign extension in all modes. So drop the limited use of it, and the local custom helper that was also extending unsigned values. We also can see that the flag checks in the mult/mac insns have the same behavior with sign extending, so add a helper func to keep the logic the same in both places.

sim: bfin: fix clear/set/toggle GPIO handling The clear/set/toggle MMRs aren't backed by "real" data; they implicitly perform bit operations on the associated data register. So when we go to process writes to them, we need to adjust the pointer accordingly so that the actual backing data is modified. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

sim: bfin: fix inverted W1C logic When I originally wrote the w1c helper funcs, I used it in a few places. Then I forgot how it worked and when I later documented it, I described the 3rd arg in the exact opposite way it is actually used. This error propagated to a bunch of devices registers that were not explicitly tested (a bunch of the devices are stubs which merely exist to say "no device is connected" to make device drivers happy). So once the documentation is unscrewed, fix all of the broken call sites. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

sim: bfin: fix thinko in SIC pin encoding When encoding the SIC/pin info into unique input port ids, I used bases of 100 when I meant to use 0x100. Rather than simply fix the decoding math in the different functions, create a few helper macros to simplify the SIC/pin encoding and decoding steps. This makes the resulting tables nice & clear.
