2016-01-04sim: punt x86-specific bswap logicMike Frysinger2-21/+6
The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
2016-01-03sim: parse_args: display getopt error ourselvesMike Frysinger2-3/+5
Fix a long standing todo where we let getopt write directly to stderr when an invalid option is passed. Use the sim io funcs instead as they go through the filtered callbacks that gdb wants.
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 Frysinger3-19/+25
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.
2016-01-01GDB copyright headers update after running GDB's copyright.py script.Joel Brobecker3-3/+3
gdb/ChangeLog: Update year range in copyright notice of all files.
2015-12-27sim: unify sim-hloadMike Frysinger2-1/+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 Frysinger3-6/+6
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.
2015-12-15Fix invalid left shift of negative valueDominik Vogt2-1/+5
Fix occurrences of left-shifting negative constants in C code. sim/arm/ChangeLog: * thumbemu.c (handle_T2_insn): Fix left shift of negative value. * armemu.c (handle_v6_insn): Likewise. sim/avr/ChangeLog: * interp.c (sign_ext): Fix left shift of negative value. sim/mips/ChangeLog: * micromips.igen (process_isa_mode): Fix left shift of negative value. sim/msp430/ChangeLog: * msp430-sim.c (get_op, put_op): Fix left shift of negative value. sim/v850/ChangeLog: * simops.c (v850_bins): Fix left shift of negative value.
2015-11-22sim: avr: move global state to sim/cpu stateMike Frysinger3-134/+157
We don't want global variables in the sim as all state should be in the sim state or in the cpu state. This pushes down all that logic for avr.
2015-11-22sim: avr: switch to common sim-regMike Frysinger2-4/+14
This is not entirely useful as avr doesn't (yet) store its register state in the cpu state, but it does allow for switching to the common code for these functions.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger2-3/+5
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 Frysinger2-6/+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 Frysinger2-13/+28
This helps standardize the configure --help output.
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.
2015-04-27sim: avr: Fix 'multiple definition of sim_{read,write}'Senthil Kumar Selvaraj2-1/+6
This patch does whatever was done in https://sourceware.org/ml/gdb-patches/2015-04/msg00437.html to fix broken gdb build for the AVR target.
2015-04-18sim: unify SIM_CPU definitionMike Frysinger2-2/+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 Frysinger2-1/+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.
2015-04-16sim: avr/mcore/moxie: fill out sim-cpu pc fetch/store helpersMike Frysinger2-0/+28
This makes the common sim-cpu logic work.
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.
2015-04-13sim: 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: run: punt!Mike Frysinger2-2/+4
Now that all targets have been converted to nrun, we can finally punt this old inconsistent interface. A few stray references to the old run were sprinkled about; clean them up in the process. We leave behind the run(1) man page mostly so that we get it updated for the new nrun interface.
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.
2015-03-28sim: avr: convert to nrun.oMike Frysinger7-843/+1378
Looks like a lot more work than actually was -- the main decode loop was de-indented by dropping the loop as a step-once function.
2015-03-16sim: rename tconfig.in to tconfig.hMike Frysinger4-21/+20
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: make nrun the default run programMike Frysinger2-0/+11
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.
2015-02-19sim: drop unused sim_kill functionMike Frysinger2-6/+4
This has been deprecated for a long time and no one calls it.

2014-03-10sim: constify arg to sim_do_commandMike Frysinger2-1/+5
It is rare for people to want to modify the cmd arg. In general, they really shouldn't be, but a few still do. For those who misbehave, dupe the string locally so they can bang on it.
2014-03-05sim: constify prog_nameMike Frysinger2-3/+6
There's no need for the prog_name handed down to the core to be mutable, so add const markings to it and all the related funcs.

2013-06-05sim: use AM_MAINTAINER_MODEMike Frysinger3-13/+72
I noticed the sim code is using an old implementation of the maintainer logic. I cut it over to the new macro (like gdb has been doing). In practice, it makes no difference currently as nothing in the sim tree uses it, but I have a follow up commit for the Blackfin tree that needs it.

2012-06-15Define PACKAGE macro in all sims' config.h.Joel Brobecker3-0/+19
Some of the common includes in include/gdb such as callback.h include bfd.h. But there was a recent change in bfd-in.h to require that config.h be included before bfd.h can be included: /* PR 14072: Ensure that config.h is included first. */ #if !defined PACKAGE && !defined PACKAGE_VERSION #error config.h must be included before this header #endif PACKAGE_VERSION is always defined by default by the AC_INIT autoconf macro, but PACKAGE isn't.

2012-03-24[PATCH] sim: make sure to include strsignal prototypeMike Frysinger4-126/+225
Before POSIX standardized strsignal(), old systems would hide the prototype unless the normal extension defines were enabled. So use the AC_USE_SYSTEM_EXTENSIONS helper for that. Then make sure we include string.h ourselves in nrun.c rather than relying on implicit includes via other sim headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-10-18sim: rename common/aclocal.m4 to common/acinclude.m4Mike Frysinger2-1/+5
Automake likes to dump macros automatically used into the aclocal.m4 file, but the common/aclocal.m4 naming prevents that. So rename it to the more normal "acinclude.m4" so the aclocal tool can work. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Now that the sourceware tree generally requires autoconf-2.64, update the sim tree to require that too. This allows us to drop the long standing SIM_AC_COMMON/common.m4 workaround as autoconf 2.64+ seems to work for me. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-16sim: add sim_complete_command stubs for non-common-using portsMike Frysinger2-0/+10
For the ports that don't use the common/ subdir, we need to add stub funcs to them to avoid build failures with gdb and command completion. These do not implement the actual completion functionality ... any port that wants that can either convert to the common/ subdir, or fill out the function on their own time.
