2023-12-22sim: frv: fix -Wshadow=local warningsMike Frysinger2-4/+3
Delete redundant decls, and rename conflicting vars.
2023-12-22sim: cgen: regenerate decode tables to avoid shadow warningsMike Frysinger1-146/+146
Use latest cgen to regenerate the decode tables which has some shadow warning fixes with "val" variables.
2023-12-21sim: mloop: add #line pragmas everywhereMike Frysinger1-0/+4
This will make compiler diagnostics much better with generated code so people can understand the original source file.
2023-12-21sim: frv: fix -Wimplicit-fallthrough warningsMike Frysinger2-3/+3
Replace some fall through comments with the attribute.
2023-12-21sim: signal: mark signal callback funcs as noreturn since they don't returnMike Frysinger1-1/+1
All funcs already call other funcs that don't return. The mips port is the only exception because its generic exception handler can return in the case of normal exceptions. So while the exceptions its signal handler triggers doesn't return, we can't express that conditional logic. So add some useless abort calls to make the compiler happy.
2023-12-20sim: cgen: unify the genmloop logic a bitMike Frysinger1-4/+3
Pull out the common parts of the genmloop invocation into the common code. This will make it easier to add more, and make the per-port differences a little more obvious.
2023-12-19sim: frv: enable warnings in memory.cMike Frysinger2-2/+1
Fix one minor pointer-sign warning to enable warnings in general for this file. Reading the data as signed and then returning it as unsigned should be functionally the same in this case.

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.
2023-08-17Re: sim frv: Add a missing return value for frvbf_check_acc_range.Alan Modra1-1/+1
Commit f00b50d057 went the wrong way. As the comment says this function is only applicable to fr550. If not fr550 return 1, meaning we don't have acc restrictions.
2023-01-18sim: info: convert verbose field to a boolMike Frysinger1-2/+2
The verbose argument has always been an int treated as a bool, so convert it to an explicit bool. Further, update the API docs to match the reality that the verbose value is actually used by some of the internal modules.
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.
2023-01-11sim: build: drop subdir Makefile.in filesMike Frysinger1-21/+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: frv: move arch-specific file compilation to top-levelMike Frysinger2-9/+6
The arch-specific flags are only used by the arch-specific modules, not the common/ files, so we can delete them too.
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: frv: move libsim.a creation to top-levelMike Frysinger2-11/+48
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: frv: hoist cgen rules to top-levelMike Frysinger2-24/+11
2023-01-01sim: replace -I$srcroot/bfd include with -I$srcrootMike Frysinger1-1/+1
Clean up includes a bit by making ports include bfd/ headers explicitly. This matches other projects, and makes it more clear where these headers are coming from.
2023-01-01sim: replace -I$srcroot/opcodes include with -I$srcrootMike Frysinger2-3/+3
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 Brobecker36-36/+36
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: 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: move bfd.h include out of sim-main.hMike Frysinger1-0/+1
Not all arches include this in sim-main.h, and the ones that do don't actually use bfd defines in the sim-main.h header. Prune it to make sim-main.h simpler so we can kill it off entirely in the future. We add the include to the files that utilize e.g. bfd_vma though.
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: 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: frv: invert sim_cpu storageMike Frysinger3-23/+18
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 Frysinger1-14/+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.
2022-11-02sim: common: change sim_{fetch,store}_register helpers to use void* buffersMike Frysinger1-2/+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.
2022-05-13sim: remove use of PTRAlan Modra1-2/+2
PTR will soon disappear from ansidecl.h. Remove uses in sim. Where a PTR cast is used in assignment or function args to a void* I've simply removed the unnecessary (in C) cast rather than replacing with (void *).
2022-01-01sim: tweak copyright lines for gnulib update-copyrightMike Frysinger1-1/+1
The regex it uses does not like so many leading spaces which causes it to think the files lack copyright. Trim them down so the script can find & update them accordingly.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker35-35/+35
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: frv: resolve syscalls dynamicallyMike Frysinger1-2/+1
Avoid use of TARGET_<syscall> defines and rely on the callback layers to resolve these dynamically so we can support multiple syscall layers instead of assuming the newlib/libgloss numbers all the time.
2021-11-19sim: install various doc filesMike Frysinger1-0/+3
2021-11-16sim: callback: expose argv & environMike Frysinger1-1/+8
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 Frysinger1-5/+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.
2021-11-10sim: frv: flip trapdump default back to offMike Frysinger1-1/+1
When I refactored this by scoping it to sim-frv-xxx in commit e7954ef5e5ed90fb7d28c013518f4c2e6bcd20a1 ("sim: frv: scope the unique configure flag"), I changed the default from off to on. While the feature is nice for developers, it breaks a bunch of tests which aren't expecting this extra output. So flip it back to off by default.
