2021-08-17sim: rename ChangeLog files to ChangeLog-2021Mike Frysinger1-2297/+0
Now that ChangeLog entries are no longer used for sim patches, this commit renames all relevant sim ChangeLog to ChangeLog-2021, similar to what we would do in the context of the "Start of New Year" procedure. The purpose of this change is to avoid people merging ChangeLog entries by mistake when applying existing commits that they are currently working on. Also throw in a .gitignore entry to keep people from adding new ChangeLog files anywhere in the sim tree.
2021-07-01sim: m32r: merge with common configure scriptMike Frysinger1-0/+6
Now that the traps code has been unified, the configure script has no unique logic in it, so it can be merged into the single common one.
2021-07-01sim: m32r: reformat linux traps codeMike Frysinger1-0/+4
Do this as a sep commit to try and make the history easier to review.
2021-07-01sim: m32r: unify ELF & Linux traps logicMike Frysinger1-0/+12
This makes the simulator work the same regardless of the target (bare metal m32r-elf or Linux m32r-linux-gnu) by unifying the traps code. It was mostly already the same with the only difference being support for trap #2 reserved for Linux syscalls. We can move that logic to runtime by checking the current environment operating mode instead.
2021-07-01sim: m32r: replace custom endian helpers with sim-endianMike Frysinger1-0/+10
This improves the logic a bit by making the host<->target translations a bit more clear. The structs still bleed way too much between the two worlds, but let's fix one thing at a time.
2021-07-01sim: m32r: fix virtual environment with Linux targetsMike Frysinger1-0/+5
We don't want to handle Linux syscalls when in the virtual environment, just the user environment, so adjust the Linux traps logic to check for that specifically (instead of just skipping the operating environment). Also tweak some testcases to explicitly specify the environment they run under rather than relying on the default matching their needs. This gets the tests passing for all m32r targets.
2021-07-01sim: m32r: namespace Linux syscall tableMike Frysinger1-0/+5
The use of __NR_ defines in here conflicts a lot with the standard host syscalls, sometimes leading to build errors (when the numbers happen to be the same we get duplicate case handlers), and other times leading to misbehavior (where the m32r syscall # is not what is actually checked). Namespace these using the standard that we already use: change the __NR_ to TARGET_LINUX_SYS_ with a simple `sed`. Also add a few missing includes so the code at least compiles.
2021-06-30sim: unify scache settingsMike Frysinger1-0/+6
The cgen scache module is enabled by every cgen port, and with the same default value of 16k (which matches the common default value). Let's pull this option out of the individual ports (via CPPFLAGS) and into the common code (via config.h). The object itself is compiled only for cgen ports atm, so that part doesn't change. The scache code is initialized dynamically via the modules.c logic. That's why the profile code needs an additional CGEN_ARCH check. This will allow us to collapse arch configure files more. Merging the source files will require more future work, but integrating the cgen & non-cgen worlds itself will take a lot.
2021-06-30sim: move default model to the runtime sim stateMike Frysinger1-0/+7
This kills off another compile-time option by moving the setting to the individual arch runtimes. This will allow dynamic selection by the arch when doing a single build with multiple arches. The sim_model_init rework is a little funky. In the past it was disabled entirely if no default model was set. We maintain the spirit of the logic by gating the fallback logic on whether the port has defined any models.
2021-06-30sim: namespace sim_machsMike Frysinger1-0/+7
We want to do a single build with all arches in one binary which means we need to namespace sim_machs on a per-arch basis. Move it from a global variable to the sim description structure so it can be setup at runtime. Changing the SIM_MODEL->num from an enum to an int is unfortunate, but we specifically don't want to maintain a centralized list anymore, and this was never used directly in common code, just passed to per-arch callbacks.
2021-06-29sim: model: constify sim_machs storageMike Frysinger1-0/+4
The array of pointers is never modified, so mark it const so it ends up in the read-only data section.
2021-06-28sim: cgen: delete unused record_trace_results functionsMike Frysinger1-0/+6
Since there are no callers of this anywhere, nor is the function implemented by anyone, drop it across the board to cleanup warnings.
2021-06-24sim: callback: extend syscall interface to handle 7 argsMike Frysinger1-0/+4
The Linux syscall interface, depending on architecture, handles up to 7 arguments. Extend the callback API to handle those.
2021-06-22sim: drop configure scripts for simple portsMike Frysinger1-0/+4
These ports only use the pieces that have been unified, so we can merge them into the common configure script and get rid of their unique one entirely. We still compile & link separate run programs, and have dedicated subdir Makefiles, but the configure script portion is merged.
2021-06-21sim: unify hardware settingsMike Frysinger1-0/+5
Move these options up to the common dir so we only test & export them once across all ports.
2021-06-21sim: hw: rework configure option & device selectionMike Frysinger1-0/+6
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.
2021-06-20sim: delete SIM_AC_COMMON macroMike Frysinger1-0/+5
Now that we've moved all content out to the common file, this is empty and can be deleted it entirely.
2021-06-20sim: unify general maintainer settingsMike Frysinger1-0/+5
Move these options up to the common dir so we only test & export them once across all ports. This takes a page from the cgen maint logic to make $(MAINT) work for non-automake Makefiles which will allow us to merge it together.
2021-06-20sim: unify cgen maintainer settingsMike Frysinger1-0/+6
Move these options up to the common dir so we only test & export them once across all ports. It makes it available to targets that aren't cgen-based, but those will just ignore the settings, so it shouldn't be an issue.
2021-06-20sim: move sim-inline to the common codeMike Frysinger1-0/+5
This will allow us to build the common code with the same inline settings as the arch subdirs, and only do the test once.
2021-06-19sim: unify bfd library dependency testing logicMike Frysinger1-0/+5
Move these options up to the common dir so we only test & export them once across all ports.
2021-06-19sim: unify various library testing logicMike Frysinger1-0/+4
Move these options up to the common dir so we only test & export them once across all ports.
2021-06-18sim: unify -Werror build settingsMike Frysinger1-0/+4
Move these options up to the common dir so we only test & export them once across all ports. It also enables -Werror usage on the common files we've been pulling out of arch subdirs.
2021-06-18sim: move -Werror disabling to MakefileMike Frysinger1-0/+6
For the ports that still don't build with -Werror, rather than disable the flag at configure time, do it at make time. This will allow us to unify these tests in the common sim configure script.
2021-06-18sim: split sim-signal.h include outMike Frysinger1-0/+5
The sim-basics.h is too big and includes too many things. This leads to some arch's sim-main.h having circular loop issues with defs, and makes it hard to separate out common objects from arch-specific defs. By splitting up sim-basics.h and killing off sim-main.h, it'll make it easier to separate out the two.
2021-06-17sim: overhaul & unify endian settings managementMike Frysinger1-0/+6
The m4 macro has 2 args: the "wire" settings (which represents the hardwired port behavior), and the default settings (which are used if nothing else is specified). If none are specified, the arch is expected to support both, and the value will be probed based on the user runtime options or the input program. Only two arches today set the default value (bpf & mips). We can probably let this go as it only shows up in one scenario: the sim is invoked, but with no inputs, and no user endian selection. This means bpf will not behave like the other arches: an error is shown and forces the user to make a choice. If an input program is used though, we'll still switch the default to that. This allows us to remove the WITH_DEFAULT_TARGET_BYTE_ORDER setting. For the ports that set a "wire" endian, move it to the runtime init of the respective sim_open calls. This allows us to change the WITH_TARGET_BYTE_ORDER to purely a user-selected configure setting if they want to force a specific endianness. With all the endian logic moved to runtime selection, we can move the configure call up to the common dir so we only process it once across all ports. The ppc arch was picking the wire endian based on the target used, but since we weren't doing that for other biendian arches, we can let this go too. We'll rely on the input selecting the endian, or make the user decide.
2021-06-16sim: drop obsolete AC_EXEEXT callMike Frysinger1-0/+4
The current autoconf 2.69 defines this to nothing because the logic in AC_PROG_CC takes care of it all the time now. Delete the call.
2021-06-16sim: drop arch-specific config.hMike Frysinger1-0/+5
All of the settings in here are handled by the common top-level config.h, so drop the individual arch-config.h files entirely. This will also help guarantee that we don't add any new arch specific defines that would affect common code which will help with the effort of unifying them.
2021-06-15sim: move dv-sockser define to CPPFLAGSMike Frysinger1-0/+4
This is the only define left in m4/ that is not in the common config.h, so move it to sim_hw_cflags so we can drop the arch-specific config.h.
2021-06-12sim: start unifying portability shimsMike Frysinger1-0/+4
There are some functions that gnulib does not yet provide fallbacks for, so start a common file of our own for holding existing stubs.
2021-06-12sim: overhaul alignment settings managementMike Frysinger1-0/+5
Currently, the sim-config module will abort if alignment settings haven't been specified by the port's configure.ac. This is a bit weird when we've allowed SIM_AC_OPTION_ALIGNMENT to seem like it's optional to use. Thus everyone invokes it. There are 4 alignment settings, but really only 2 matters: strict and nonstrict. The "mixed" setting is just the default ("unset"), and "forced" isn't used directly by anyone (it's available as a runtime option for some ports). The m4 macro has 2 args: the "wire" settings (which represents the hardwired port behavior), and the default settings (which are used if nothing else is specified). If none are specified, then the build won't work (see above as if SIM_AC_OPTION_ALIGNMENT wasn't called). If default settings are provided, then that is used, but we allow the user to override at runtime. Otherwise, the "wire" settings are used and user runtime options to change are ignored. Most ports specify a default, or set the "wire" to nonstrict. A few set "wire" to strict, but it's not clear that's necessary as it doesn't make the code behavior, by default, any different. It might make things a little faster, but we should provide the user the choice of the compromises to make: force a specific mode at compile time for faster runtime, or allow the choice at runtime. More likely it seems like an oversight when these ports were initially created, and/or copied & pasted from existing ports. With all that backstory, let's get to what this commit does. First kill off the idea of a compile-time default alignment and set it to nonstrict in the common code. For any ports that want strict alignment by default, that code is moved to sim_open while initializing the sim. That means WITH_DEFAULT_ALIGNMENT can be completely removed. Moving the default alignment to the runtime also allows removal of setting the "wire" settings at configure time. Which allows removing of all arguments to SIM_AC_OPTION_ALIGNMENT and moving that call to common code. The macro logic can be reworked to not pass WITH_ALIGNMENT as -D CPPFLAG and instead move it to config.h. All of these taken together mean we can hoist the macro up to the top level and share it among all sims so behavior is consistent among all the ports.
2021-06-12sim: unify assert build settingsMike Frysinger1-0/+4
Move the --sim-enable-assert option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify platform function & header testsMike Frysinger1-0/+4
Move the various platform tests up a level to avoid duplication across the ports. When building multiple versions, this speeds things up a bit. For now we move the obvious stuff up a level, but we don't turn own the config.h entirely just yet -- we still have some tests related to libraries that need consideration.
2021-06-09sim: cgen: inline cgen_init logicMike Frysinger1-0/+4
This function has done only one thing: post-process command line settings to see if profiling or tracing has been enabled, and if so, set the run_fast_p flag in the simulator state. That flag is only used in one place: to select the fast or slow cgen engine. By inlining the run_fast_p logic to the one place it's used, we can delete a good amount of logic specific to cgen ports: both the call to cgen_init and the conditional simulator state. This in turn allows us to have a single simulator state struct across all ports so we can share objects more between them, and makes the sim_open calls look more consistent.
2021-05-17sim: cgen: invert sim_state storage for cgen portsMike Frysinger1-0/+4
2021-05-16sim: switch config.h usage to defs.hMike Frysinger1-0/+7
The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise.
2021-05-16sim: riscv: move __int128 check to configureMike Frysinger1-0/+4
2021-05-04Add missing stdlib.h includes to simTom Tromey1-0/+4
This updates the various "mloop.in" files to emit an include of stdlib.h, to avoid warnings about 'abort' being undeclared. One such warning now remains, in mn10300.igen. I don't know offhand the best way to fix this one. 2021-05-04 Tom Tromey <tromey@adacore.com> * mloop.in: Include <stdlib.h>. sim/iq2000/ChangeLog 2021-05-04 Tom Tromey <tromey@adacore.com> * mloop.in: Include <stdlib.h>. sim/lm32/ChangeLog 2021-05-04 Tom Tromey <tromey@adacore.com> * mloop.in: Include <stdlib.h>. sim/m32r/ChangeLog 2021-05-04 Tom Tromey <tromey@adacore.com> * mloop.in: Include <stdlib.h>. sim/or1k/ChangeLog 2021-05-04 Tom Tromey <tromey@adacore.com> * mloop.in: Include <stdlib.h>.
2021-05-04sim: add support for build-time ar & ranlibMike Frysinger1-0/+4
This is needed when building for a target whose ar & ranlib are incompatible with the current build system. For example, building for Windows on a Linux system. Then manually import the automake rule for libigen.a, but tweak the tool variables to use the FOR_BUILD variants.
2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger1-0/+4
While libiberty provides a definition for this for systems that lack the function (e.g. Windows), it doesn't provide a prototype. So add our own local copy in the one file that uses the func.
2021-04-26sim: nltvals: unify common syscall tablesMike Frysinger1-0/+4
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.
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/+8
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.

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.

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.
2021-04-12sim: 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.

This updates various parts of the sim to include missing system headers. I made the includes unconditional, because other parts of the tree are already doing this. 2021-04-08 Tom Tromey <tom@tromey.com> * traps.c: Include stdlib.h. * cris-tmpl.c: Include stdlib.h. sim/erc32/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * func.c: Include sys/time.h. sim/frv/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * traps.c: Include stdlib.h. * registers.c: Include stdlib.h. * profile.c: Include stdlib.h. * memory.c: Include stdlib.h. * interrupts.c: Include stdlib.h. * frv.c: Include stdlib.h. * cache.c: Include stdlib.h. sim/iq2000/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * iq2000.c: Include stdlib.h. sim/m32r/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * traps.c: Include stdlib.h. * m32r.c: Include stdlib.h. sim/ppc/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * emul_unix.c: Include time.h.
