2023-08-19sim regenAlan Modra10-25/+45
This regenerates sim files.

2023-08-19sim regen preparationAlan Modra2-11/+11
Regerating sim loses commit 1be79b1ebfad from sim/lm32/cpu.h, a generated file, so this patch move those declarations to sim/lm32/sim-main.h.
2023-08-19sim --enable-cgen-maintAlan Modra1-2/+2
I had reason yesterday to want to regenerate configury files which I do with --enable-maintainer-mode, and added --enable-cgen-maint accidentally. The first problem I hit is that sim looks for cgen in a different directory by default than opcodes, and I had my source layout set up for opcodes rather than sim. Fix that by making both use ../cgen first, then ../../cgen relative to sim/ and opcodes/. The next problem was that various sim local.mk files expected generated sources in the build dir rather than the source dir. Fix that by adding $(srcdir) to paths. Finally, the generated iq2000 files had a compile error, fixed by the cpu/iq2000.cpu patch. cpu/ * iq2000.cpu (syscall): Add pc arg. opcodes/ * configure.ac (cgendir): Default to ../../cgen, but use ../cgen if found there. * configure: Regenerate. sim/m4/ * sim_ac_option_cgen_maint.m4 (cgendir): Look in ../cgen too. sim/ * cris/local.mk: Add $(srcdir) to paths for regenerated source. * frv/local.mk: Likewise. * iq2000/local.mk: Likewise. * lm32/local.mk: Likewise. * m32r/local.mk: Likewise. * or1k/local.mk: Likewise. * Makefile.in: Regenerate. * configure: Regenerate.
2023-01-15sim: modules.c: fix generation after recent refactorsMike Frysinger1-0/+3
Add explicit arch-specific modules.c rules to keep the build from generating an incorrect common/modules.c. Otherwise the pattern rules would cascade such that it'd look for $arch/modules.o which turned into common/modules.c which triggered the gen rule. My local testing of this code didn't catch this bug because of how Automake manages .Po (dependency files) in incremental builds -- it was adding extra rules that override the pattern rules which caused the build to generate correct modules.c files. But when building from a cold cache, the pattern rules would force common/modules.c to be used leading to crashes at runtime.
2023-01-14sim: common: move modules.c to source trackingMike Frysinger1-1/+2
This makes sure the arch-specific modules.c wildcard is matched and not the common/%.c so that we compile it correctly. It also makes sure each subdir has depdir logic enabled.
2023-01-14sim: build: drop most recursive build depsMike Frysinger1-2/+1
Now that we build these objects in the top dir & generate modules.c there, we don't need to generate them all first -- we can let the normal dependency graph take care of building things in parallel.
2023-01-14sim: common: move libcommon.a objects to sourcesMike Frysinger1-2/+2
This simplifies the build logic and avoids an Automake bug where the common_libcommon_a_OBJECTS variable isn't set in the arch libsim.a DEPENDENCIES for targets that, alphabetically, come before "common". We aren't affected by that bug with the current code, but as we move things out of SIM_ALL_RECURSIVE_DEPS and rely on finer dependencies, we will trip over it.
2023-01-14sim: build: drop AM_MAKEFLAGS settingsMike Frysinger1-1/+0
We don't have any recursive builds anymore, so we can drop this logic.
2023-01-11sim: build: drop subdir Makefile.in filesMike Frysinger1-8/+0
These aren't used anymore, so punt them all.
2023-01-10sim: move arch-specific file compilation of common/ files to top-levelMike Frysinger1-2/+2
2023-01-10sim: lm32: move arch-specific file compilation to top-levelMike Frysinger1-3/+0
2023-01-10sim: build: drop support for creating libsim.a in subdirsMike Frysinger1-2/+0
Now that all ports have moved to creating libsim.a in the top-level, drop all the support code to create it in a subdir.
2023-01-10sim: lm32: move libsim.a creation to top-levelMike Frysinger2-8/+35
The objects are still compiled in the subdir, but the creation of the archive itself is in the top-level. This is a required step before we can move compilation itself up, and makes it easier to review. The downside is that each object compile is a recursive make instead of a single one. On my 4 core system, it adds ~100msec to the build per port, so it's not great, but it shouldn't be a big deal. This will go away of course once the top-level compiles objects.
2023-01-10sim: modules: trigger generation from top-levelMike Frysinger1-0/+1
Add rules for tracking generated subdir modules.c files. This doesn't actually generate the file from the top-level, but allows us to add rules that need to be ordered wrt it. Once those changes land, we can rework this to actually generate from the top-level. This currently builds off of the objects that go into the libsim.a as we don't build those from the top-level either. Once we migrate that up, we can switch this to the source files directly. It's a bit hacky overall, but makes it easier to migrate things in smaller chunks, and we aren't going to keep this logic long term.
2023-01-02sim: build: move generated headers to built sourcesMike Frysinger1-1/+2
Automake's automatic header deptracking has a bootstrap problem where it can't detect generated headers when compiling. We've been handling that by adding a custom SIM_ALL_RECURSIVE_DEPS variable, but that only works when building objects recursively in subdirs. As we move those out to the top-level, we don't have any recursive steps anymore. The Automake approach is to declare those headers in BUILT_SOURCES. This isn't completely foolproof as the Automake manual documents: it only activates for `make all`, not `make foo.o`, but that shouldn't be a huge limitation as it only affects the initial compile. After that, rebuilds should work fine.
2023-01-02sim: lm32: hoist cgen rules to top-levelMike Frysinger2-22/+11
2023-01-01sim: replace -I$srcroot/opcodes include with -I$srcrootMike Frysinger1-2/+2
Clean up includes a bit by making ports include opcodes/ headers explicitly. This matches other projects, and makes it more clear where these headers are coming from.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker20-20/+20
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-12-25sim: cpu: change default init to handle all cpusMike Frysinger1-1/+1
All the runtimes were only initializing a single CPU. When SMP is enabled, things quickly crash as none of the other CPU structs are setup. Change the default from 0 to the compile time value.
2022-12-23sim: lm32/m32r: drop redundant opcode/cgen.h includeMike Frysinger1-1/+0
The xxx-desc.h header file already includes this, and it's how the other cgen ports are getting it, so drop it from these two.
2022-12-23sim: cgen: move symcat.h include to where it's usedMike Frysinger1-1/+0
Move this out of the global sim-main.h and to the few files that actually use functions from it. Only the cgen ports were pulling this, so this makes cgen & non-cgen behave more the same.
2022-12-23sim: cgen: move cgen-types.h include to cgen-defs.hMike Frysinger1-1/+0
The cgen-types.h header sets up types that are needed by cgen-defs.h, so move the include out of sim-main.h and to that header. It might be needed in other specific modules, but for now let's kick it out of sim-main.h to make some progress. Things still build with just this.
2022-12-22sim: use bfd_vma when reading start addr from bfd infoMike Frysinger1-1/+1
Since SIM_ADDR is always 32-bit, it might truncate the address with 64-bit ELFs. Since we load that addr from the bfd, use the bfd_vma type which matches the bfd_get_start_address API.
2022-12-21sim: build: hoist lists of hw devices upMike Frysinger2-4/+5
We need these in the top-level to generate libsim.a, but also in the subdirs to generate hw-config.h. Move it to the local.mk, and pass it down when running recursive make. This avoids duplication, and makes it available to both. We can simplify this once we move the various steps up to the top-level too.
2022-12-21sim: enable common sim_cpu usage everywhereMike Frysinger1-2/+0
All ports should be migrated now. Drop the SIM_HAVE_COMMON_SIM_CPU knob and require it be used everywhere now.
2022-12-21sim: lm32: invert sim_cpu storageMike Frysinger3-12/+7
The cpu.h change is in generated cgen code, but that has been sent upstream too, so the next regen should include it automatically.
2022-12-20sim: move register headers into sim/ namespace [PR sim/29869]Mike Frysinger1-1/+1
These headers define the register numbers for each port to implement the sim_fetch_register & sim_store_register interfaces. While gdb uses these, the APIs are part of the sim, not gdb. Move the headers out of the gdb/ include namespace and into sim/ instead.
2022-11-05sim: run: move linking into top-levelMike Frysinger1-0/+8
Automake will run each subdir individually before moving on to the next one. This means that the linking phase, a single threaded process, will not run in parallel with anything else. When we have to link ~32 ports, that's 32 link steps that don't take advantage of parallel systems. On my really old 4-core system, this cuts a multi-target build from ~60 sec to ~30 sec. We eventually want to move all compile+link steps to this common dir anyways, so might as well move linking now for a nice speedup. We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care of the install ourselves rather than letting automake process it.
2022-11-04sim: build: remove various obsolete generation dep variablesMike Frysinger1-9/+0
These manual settings were necessary when we weren't doing automatic header dependency tracking. That was changed a while ago, and we use automake now to do it all for us. As a result, many of these vars aren't even referenced anymore. Further, some of the source file generation (e.g. .c files, or igen, or cgen outputs) were moved to the common automake build, and it takes care of dependency tracking for us with the object files.
2022-11-04sim: cleanup unused SIM_EXTRA_CFLAGSMike Frysinger1-3/+0
We want to eventually delete this, so at least drop the empty ones.
2022-11-02sim: common: change sim_{fetch,store}_register helpers to use void* buffersMike Frysinger1-4/+2
When reading/writing arbitrary data to the system's memory, the unsigned char pointer type doesn't make that much sense. Switch it to void so we align a bit with standard C library read/write functions, and to avoid having to sprinkle casts everywhere.
2022-10-31sim: reg: constify store helperMike Frysinger1-1/+1
These functions only read from memory, so mark the pointer as const.
2022-10-24sim/lm32: fix some missing function declaration warningsAndrew Burgess4-3/+17
In the lm32 simulator, I was seeing some warnings about missing function declarations. The lm32 simulator has a weird header structure, in order to pull in the full cpu.h header we need to define WANT_CPU_LM32BF. This is done in some files, but not in others. Critically, it's not done in some files that then use functions declared in cpu.h In this commit I added the missing #define so that the full cpu.h can be included. After doing this there are still a few functions that are used undeclared, these functions appear to be missing any declarations at all, so I've added some to cpu.h. With this done all the warnings when compiling lm32 are resolved for both gcc and clang, so I've removed the SIM_WERROR_CFLAGS line from Makefile.in, this allows lm32 to build with -Werror.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker20-20/+20
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-12-09sim: use ## for automake commentsMike Frysinger1-19/+19
The ## marker tells automake to not include the comment in its generated output, so use that in most places where the comment only makes sense in the inputs.
2021-11-28sim: iq2000/lm32/m32c/moxie/rx: switch to new target-newlib-syscall.hMike Frysinger1-2/+2
Use the new target-newlib-syscall.h to provide the target syscall defines. These code paths are written specifically for the newlib ABI rather than being generalized, so switching them to the defines rather than trying to go through the dynamic callback conversion seems like the best trade-off for now. Might have to reconsider this in the future.
2021-11-16sim: callback: expose argv & environMike Frysinger1-2/+7
Pass the existing strings data to the callbacks so that common libgloss syscalls can be implemented (which we'll do shortly).
2021-11-16sim: keep track of program environment stringsMike Frysinger1-1/+7
We've been passing the environment strings to sim_create_inferior, but most ports don't do anything with them. A few will use ad-hoc logic to stuff the stack for user-mode programs, but that's it. Let's formalize this across the board by storing the strings in the normal sim state. This will allow (in future commits) supporting more functionality in the run interface, and to unify some of the libgloss syscalls.
2021-11-15sim: split program path out of argv vectorMike Frysinger1-4/+1
We use the program argv to both find the program to run (argv[0]) and to hold the arguments to the program. Most of the time this is fine, but if we want to let programs specify argv[0] independently (which is possible in standard *NIX programs), this double duty doesn't work. So let's split the path to the program to run out into a separate field by itself. This simplifies the various sim_open funcs too. By itself, this code is more of a logical cleanup than something that is super useful. But it will open up customization of argv[0] in a follow up commit. Split the changes to make it easier to review.
2021-11-02sim: hoist cgen mloop rules up to common buildsMike Frysinger2-12/+38
These rules don't depend on the target compiler settings, so hoist the build logic up to the common builds for better parallelization. We have to extend the genmloop.sh logic a bit to allow outputting to a subdir since it always assumed cwd was the right place. We leave the cgen maintainer rules in the subdirs for now as they aren't normally run, and they rely on cgen logic that has not yet been generalized.
2021-11-01sim: lm32: reduce -Wno-error scopeMike Frysinger3-5/+5
Clean up some warnings in dv-lm32cpu, and all in sim-if, then reduce the -Werror disable to the files that still aren't clean that now that we require GNU make and can set variables on a per-object basis.
2021-10-31sim: tighten up stamp rulesMike Frysinger1-1/+2
Add a new ECHO_STAMP helper and convert existing stamp code over to it. This is mostly common rules and cgen mloop rules.
2021-10-31sim: silence stamp touch rulesMike Frysinger1-3/+3
We pretty much never care about these stamp touches, so silence them. Also switch to using $@ when it makes sense.
2021-10-31sim: standardize move-if-change rulesMike Frysinger1-2/+2
Use the srcroot path and make them all silent.
2021-08-17sim: rename ChangeLog files to ChangeLog-2021Mike Frysinger1-0/+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.
2021-06-30sim: cris/frv/iq2000/lm32: merge with common configure scriptMike Frysinger4-2896/+6
Now that the scache logic has been migrated into the common code, there's nothing specific in these configure scripts, so merge them into the common one. The frv unique logic can be moved to a dedicated include and merged in the common configure since the flag has been scoped to the arch.
2021-06-30sim: unify scache settingsMike Frysinger4-34/+7
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 Frysinger5-24/+9
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 Frysinger3-1/+11
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 Frysinger2-1/+5
The array of pointers is never modified, so mark it const so it ends up in the read-only data section.
