2021-04-23sim: simplify hardware m4 macroMike Frysinger1-0/+5
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.
2021-04-22Do not check for sys/time.h or sys/times.hTom Tromey1-0/+4
This updates the sim so that it unconditionally uses sys/time.h. This is in agreement with existing code, and a recent change to BFD. I also think that sys/times.h is never needed by the sim, so this patch removes the check and the one spot that was conditionally including it. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for sys/time.h or sys/times.h. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bpf/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * sim-utils.c: Update includes. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * simops.c: Update includes. * configure, config.in: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * rvdummy.c: Update includes. * dv-rv.c: Update includes. * configure, config.in: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ppc/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * mon.c: Update includes. * emul_unix.c: Update includes.

2021-04-22Remove and modernize dependencies in simTom Tromey1-0/+6
Some spots in the sim build used manual dependencies, and some spots did a compilation by hand but did not use the automatic dependency tracking code. This patch fixes these spots. I didn't touch ppc, because it doesn't use the common Makefile code. I also didn't touch objects that are for the build machine, because automatic dependencies don't work for those. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Makefile.in (armemu26.o, armemu32.o): Use COMPILE and POSTCOMPILE. sim/bpf/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Makefile.in (arch.o, cpu.o, sim-if.o, traps.o): Remove.

2021-04-22Require GNU makeTom Tromey1-0/+4
GDB has required GNU make for quite some time, and this patch applies this approach to the sim as well. Requiring GNU make means that automatic dependency tracking can be simple and reliable, and it also makes other refactorings simpler. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for make. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in: Require GNU make. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/pru/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/riscv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/rl78/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/rx/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/sh/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/v850/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild.
2021-04-21sim: regen against sim/m4/Mike Frysinger1-0/+4
My scripts weren't updated to use new -I../m4 as the first arg.
2021-04-21sim: use -Werror when probing for supported warning flagsSimon Marchi1-0/+4
When building with clang, we get: error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option] This is because clang only warns by default when encountering an unknown warning option, and the probe for supported warning flags is done without -Werror. All flags are therefore accepted by configure, but then it breaks when actually compiling a source file with -Werror. This is equivalent to this commit in gdb: 3e019bdc20eb81b91ab5bc774386201b874c0bac gdb: Use -Werror when checking for (un)supported warning flags We then see some other compilation errors when building with clang and -Werror, they can be dealt with later.
2021-04-18sim: switch to AC_CHECK_FUNCS_ONCE & merge a littleMike Frysinger1-0/+4
This avoids duplicate tests for functions between common m4, arches, and any other sources that would trigger func tests. Also manually delete known duplicate function tests between the m4, bfin, and v850 ports.
2021-04-15sim lm32: Use a known-good shell with genmloop.sh.John Baldwin1-0/+4
Explicitly use a known-good shell found by autoconf for executing additional scripts in genmloop.sh rather than the building user's shell. sim/lm32/ChangeLog: * Makefile.in: Pass -shell to genmloop.sh.
2021-04-12sim: cgen: move cgen_cpu_max_extra_bytes logic into the common codeMike Frysinger1-0/+4
Every arch handles this the same way, so move it to the common code. This will also make unifying the sim_cpu structure easier.
2021-04-08Do not use old-style definitions in simTom Tromey1-0/+5
This changes all the non-generated (hand-written) code in sim to use "new" (post-K&R) style function definitions. 2021-04-08 Tom Tromey <tom@tromey.com> * bpf.c (bpf_def_model_init): Use new-style declaration. sim/common/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * cgen-utils.c (RORQI, ROLQI, RORHI, ROLHI, RORSI, ROLSI): Use new-style declaration. sim/erc32/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * sis.c (run_sim, main): Use new-style declaration. * interf.c (run_sim, sim_open, sim_close, sim_load) (sim_create_inferior, sim_store_register, sim_fetch_register) (sim_info, sim_stop_reason, flush_windows, sim_do_command): Use new-style declaration. * help.c (usage, gen_help): Use new-style declaration. * func.c (batch, set_regi, set_rega, disp_reg, limcalc) (reset_stat, show_stat, init_bpt, int_handler, init_signals) (disp_fpu, disp_regs, disp_ctrl, disp_mem, dis_mem, event) (init_event, set_int, advance_time, now, wait_for_irq, check_bpt) (reset_all, sys_reset, sys_halt): Use new-style declaration. * float.c (get_accex, clear_accex, set_fsr): Use new-style declaration. * exec.c (sub_cc, add_cc, log_cc, dispatch_instruction, fpexec) (chk_asi, execute_trap, check_interrupts, init_regs): Use new-style declaration. * erc32.c (init_sim, reset, decode_ersr, mecparerror) (error_mode, decode_memcfg, decode_wcr, decode_mcr, sim_halt) (close_port, exit_sim, mec_reset, mec_intack, chk_irq, mec_irq) (set_sfsr, mec_read, mec_write, init_stdio, restore_stdio) (port_init, read_uart, write_uart, flush_uart, uarta_tx) (uartb_tx, uart_rx, uart_intr, uart_irq_start, wdog_intr) (wdog_start, rtc_intr, rtc_start, rtc_counter_read) (rtc_scaler_set, rtc_reload_set, gpt_intr, gpt_start) (gpt_counter_read, gpt_scaler_set, gpt_reload_set, timer_ctrl) (memory_read, memory_write, get_mem_ptr, sis_memory_write) (sis_memory_read): Use new-style declaration. sim/frv/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * sim-if.c (sim_open, frv_sim_close, sim_create_inferior): Use new-style declaration. sim/h8300/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * compile.c (cmdline_location): Use new-style declaration. sim/iq2000/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * sim-if.c (sim_open, sim_create_inferior): Use new-style declaration. * iq2000.c (fetch_str): Use new-style declaration. sim/lm32/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * sim-if.c (sim_open, sim_create_inferior): Use new-style declaration. sim/m32r/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * sim-if.c (sim_open, sim_create_inferior): Use new-style declaration.
2021-04-02sim: unify toolchain settingsMike Frysinger1-0/+4
The toplevel, common, and igen dirs all have their own code for setting up toolchain settings. Unify all of that in a new macro.
2021-02-28sim: require AC_PROG_CPP explicitlyMike Frysinger1-0/+4
All the scripts were using this implicitly already, so there's no real change for them, but we want to call it explicitly as the CPP tool is used to generate nltvals.def.
2021-02-21sim: common: split up acinclude.m4 into individual m4 filesMike Frysinger1-0/+5
This file is quite large and is getting unmanageable. Split it apart to follow aclocal best practices by putting one-macro-per-file. There shouldn't be any real functional changes here as can be seen in the configure script regens.
2021-02-13sim: switch to AC_CONFIG_MACRO_DIRSMike Frysinger1-0/+5
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.
2021-02-06sim: drop use of bfd/configure.hostMike Frysinger1-0/+4
These settings might have made sense in darker compiler times, but I think they're largely obsolete now. Looking through the values that get used in HDEFINES, it's quite limited, and configure itself should handle them. If we still need something, we can leverage standard autoconf macros instead, after we get a clear user report. TDEFINES was never set anywhere and was always empty, so prune that.
2021-01-11sim: call SIM_AC_OPTION_WARNINGS(no) in remaining portsMike Frysinger1-0/+5
We want all ports to opt into extra warnings as the default compiler settings lets a lot slide. Opt all the ports that haven't already in to the warning system. None of them build with -Werror, so disable that by default. Hopefully someone finds these important enough to start fixing at some point.
2021-01-11sim: clean up C11 header includesMike Frysinger1-0/+5
Since we require C11 now, we can assume many headers exist, and clean up all of the conditional includes. It's not like any of this code actually accounted for the headers not existing, just whether we could include them. The strings.h cleanup is a little nuanced: it isn't in C11, but every use of it in the codebase will include strings.h only if string.h doesn't exist. Since we now assume the C11 string.h exists, we'll never include strings.h, so we can delete it.
2021-01-09sim: clean up stale AC_PREREQ refsMike Frysinger1-0/+4
This was purged from the tree when we upgraded to autoconf-2.69, but a few references in the sim tree were missed.
2021-01-08sim: require a C11 compilerMike Frysinger1-0/+4
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.

2017-02-13sim: use ARRAY_SIZE instead of ad-hoc sizeof calculationsMike Frysinger1-0/+4
2016-08-15sim: unify symbol table handlingMike Frysinger1-0/+6
The common sim tracing code already handles loading and tracking of symbols from the target program so that it can show symbol info in trace/disassembly calls. Once we touch up the trace code and add a few API callbacks, ports don't need to do loading and searching of symbol tables themselves anymore.
2016-01-10sim: move many common settings from CPPFLAGS to config.hMike Frysinger1-0/+4
Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.
2016-01-10sim: drop unused SIM_AC_OPTION_PACKAGESMike Frysinger1-0/+4
This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
2016-01-10sim: allow the environment configure option everywhereMike Frysinger1-0/+5
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: allow the assert configure option everywhereMike Frysinger1-0/+4
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.
2016-01-10sim: drop targ-vals.def->nltvals.def indirectionMike Frysinger1-0/+4
We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.
2016-01-10sim: allow the inline configure option everywhereMike Frysinger1-0/+4
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: drop --enable-sim-{regparm,stdcall} optionsMike Frysinger1-0/+4
These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
2016-01-10sim: drop --enable-sim-cflags optionMike Frysinger1-0/+4
No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.
2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger1-0/+4
The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.
2016-01-06sim: sim_{create_inferior,open,parse_args}: constify argv/env slightlyMike Frysinger1-0/+5
2016-01-03 Mike Frysinger <vapier@gentoo.org> * sim-options.c (sim_parse_args): Mark argv array const. * sim-options.h (sim_parse_args): Likewise.
2016-01-04sim: punt x86-specific bswap logicMike Frysinger1-0/+4
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 Frysinger1-0/+4
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 Frysinger1-0/+5
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 Frysinger1-0/+6
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: iq2000/m32r/lm32/sh64: delete dead option codeMike Frysinger1-0/+6
The iq2000/m32r/sh64 option parsing logic appears to have always been dead. At least iq2000/sh64 are simply copy & paste rot from m32r. The lm32 option parsing hack here hasn't been needed for a while -- this was fixed back in commit 11409fac6b95d71a92848a4499b02d60a4f4c5bb in the common code.
2016-01-02sim: delete dead current_state globalsMike Frysinger1-0/+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.
2015-12-27sim: unify sim-hloadMike Frysinger1-0/+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 Frysinger1-0/+4
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: standardize sim_create_inferior handling of argv a bit moreMike Frysinger1-0/+4
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: sim-model: build for everyoneMike Frysinger1-0/+4
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 Frysinger1-0/+7
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 Frysinger1-0/+5
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.
2015-12-24sim: make LMA loading the default for all targetsMike Frysinger1-0/+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.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger1-0/+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: clean up redundant objectsMike Frysinger1-0/+4
Some of the target makefiles listed objects that were already pulled in via SIM_NEW_COMMON_OBJS. Clean those up.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger1-0/+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.
