2021-08-17sim: rename ChangeLog files to ChangeLog-2021Mike Frysinger1-1848/+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.
2021-06-22sim: drop configure scripts for simple portsMike Frysinger1-0/+6
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/+4
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: 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.
2021-06-17sim: overhaul & unify endian settings managementMike Frysinger1-0/+5
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: 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.
2021-05-29sim: sh: fix a few compiler warningsMike Frysinger1-0/+5
2021-05-17sim: fully merge sim_state_base into sim_stateMike Frysinger1-0/+4
Now that all ports have migrated to the new framework, drop support for the old sim_state_base layout.
2021-05-17sim: invert sim_state storageMike Frysinger1-0/+5
Currently all ports have to declare sim_state themselves in their sim-main.h and then embed the common sim_state_base & sim_cpu in it. This dynamic makes it impossible to share common object code among multiple ports because the core data structure is always different. Let's invert this relationship: common code declares sim_state, and if the port actually needs state on a per-instance basis, it can use the new arch_data field for it. Most ports don't actually use it, so they don't need to declare anything at all. This is the first in a series of changes: it adds a define to select between the old & new layouts, then converts all the ports that don't need custom state over to the new layout.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger1-0/+4
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
2021-05-14sim: create header namespaceMike Frysinger1-0/+4
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.
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: enable hardware support by defaultMike Frysinger1-0/+4
Force this on for all ports. We have a few common models that can be used, so make them generally available. If the port doesn't use any hardware (the default), then behavior is unchanged.
2021-04-22Do not check for sys/time.h or sys/times.hTom Tromey1-0/+5
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/+5
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.

2021-04-21sim: 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_HEADERS_ONCEMike Frysinger1-0/+4
This avoids duplicate tests for headers between common m4, arches, and any other sources that would trigger header tests.
2021-04-18sim: sh: switch syscalls to common nltvalsMike Frysinger1-0/+7
Rather than hand duplicate the syscall table, switch to the common nltvals framework. We have to tweak the constant names, but we get everything else for free. I made sure the constants have the same values before & after too :).
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.
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.
2021-03-13sim: introduce {COMPILE,LINK}_FOR_BUILDMike Frysinger1-0/+5
These use the same pattern as seen in the opcodes/ dir and in automake in general (ish). This helps simplify the boilerplate for building and linking build-time code, and fixes some inconsistency in flag usage. For rules that were compiling+linking in a single step, split them into separate steps so we can apply the correct set of options. This matches automake behavior too.
2021-02-28sim: require AC_PROG_CPP explicitlyMike Frysinger1-1/+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: clean up C11 header includesMike Frysinger1-0/+6
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.
2021-01-09sim: enable -Werror by default for some archesMike Frysinger1-0/+5
We've had this off for a long time because the sim code was way too full of warnings for it to be feasible. However, I've cleaned things up significantly from when this was first merged, and we can start to turn this around. Change the macro to enable -Werror by default, and allow ports to opt out. New ports will get it automatically (and we can push back on them if they try to turn it off). Also turn it off for the few ports that still hit warnings for me. All the rest will get the new default, and we'll wait for feedback if/when new issues come up.
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.
