2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess36-36/+36
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2024-01-10sim: m32r: enable warnings in traps.cMike Frysinger1-3/+0
File should be clean now!
2024-01-10sim: m32r: fixup some of the int<->pointer castsMike Frysinger1-28/+53
The m32r trap code was written for a 32-bit Linux host (and really, one whose Linux ABI matched pretty exactly). This has lead to conversions between integers and pointers which breaks down hard on 64-bit hosts. Clean up some of the functions where possible to avoid unnecessary conversions, use uintptr_t to cast 32-bit target pointers to host pointers in some places, and just stub out a few functions that can't easily be salvaged currently when sizeof(void*) is not 32-bits. This is a bit ugly, but lets us enable warnings for the whole file.
2024-01-10sim: m32r: fix missing break statementMike Frysinger1-0/+1
The ftime syscall should not fallthrough to the sync syscall. Clearly the code was missing a break statement.
2024-01-10sim: m32r: migrate ftime() to clock_gettime()Mike Frysinger1-5/+8
The ftime() function has been deprecated since POSIX-1-2004, and removed in POSIX.1-2008. It's also been deprecated/removed in glibc since 2.33. POSIX has always said the function is not portable, and its return value, timezone, and dstflag fields are unspecified. Even if Linux/glibc & m32r had defined behavior, those aren't the host for the sim runtime. So let's stop using the function and switch to clock_gettime. gnulib already has detection support for it, and it's been around since at least POSIX-1-2004.
2024-01-10sim: m32r: cleanup unused variablesMike Frysinger1-3/+1
We've been building this file with -Wno-error, so clean up unused variable warnings.
2024-01-08sim: build: clean more generated outputsMike Frysinger1-0/+1
2023-12-24sim: cgen: regenerate decode tablesMike Frysinger3-705/+705
Integrate some changes from upstream cgen that tightened up the generated output. Shouldn't be any functional changes here.
2023-12-22sim: cgen: regenerate decode tables to avoid shadow warningsMike Frysinger3-60/+60
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 Frysinger3-0/+10
This will make compiler diagnostics much better with generated code so people can understand the original source file.
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 Frysinger1-12/+9
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: m32r: fix -Wunused-variable warningsMike Frysinger1-2/+0
2023-12-14sim: m32r: fix mloop.in variant stamp depsMike Frysinger1-2/+2
The migration to local.mk in commit 0a129eb19a773d930d60b084209570f663db2053 accidentally listed the deps for all mloop steps as mloop.in instead of the various variants that m32r uses. Reported-by: Simon Marchi <simon.marchi@polymtl.ca>
2023-12-14sim: m32r: use @cpu@_fill_argbuf_tp to set trace & profile stateMike Frysinger2-16/+8
The mloop.in code does this, but these variants do not. Use it to avoid unused function warnings. The fast_p logic in these files also looks off, but that'll require a bit more work to fixup.

2023-12-07sim: m32r: fix syslog callMike Frysinger1-1/+2
The function returns void, not int. We only pass one argument to syslog (the format), so use %s as the static format instead since the emulation layer doesn't handle passing additional arguments.
2023-12-07sim: m32r: include more glibc headers for the funcs we use [PR sim/29752]Mike Frysinger1-0/+5
Not exactly portable, but doesn't make the situation worse here, and fixes a lot of implicit function warnings. Bug: https://sourceware.org/PR29752
2023-12-07sim: m32r: add more cgen prototypes for trapsMike Frysinger1-0/+12
The traps file uses a bunch of functions directly without prototypes, and we can't safely include the relevant cpu*.h files for them.
2023-12-07sim: m32r: add more cgen prototypes to enable -Werror in most filesMike Frysinger2-13/+27

2023-08-19sim --enable-cgen-maintAlan Modra1-4/+4
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.
2023-01-18sim: 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.
2023-01-15sim: m32r: fix typos in stamp dependsMike Frysinger1-2/+2
Copying & pasting the first rule missed updating the dep to the right stamp file.
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 Frysinger1-24/+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: m32r: move arch-specific file compilation to top-levelMike Frysinger2-6/+14
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: m32r: move libsim.a creation to top-levelMike Frysinger2-13/+47
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 Frysinger1-3/+5
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: m32r: hoist cgen rules to top-levelMike Frysinger2-48/+19
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 Brobecker37-37/+37
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.
2022-12-25sim: m32r: fix iterator typo when setting up cpusMike Frysinger1-1/+1
This code loops over available cpus with "c", but then looks up the cpu with "i". Fix the typo so the code works correctly with smp.
2022-12-23sim: m32r: move arch-specific settings to internal headerMike Frysinger7-22/+33
There's no need for these settings to be in sim-main.h which is shared with common/ sim code, so move it all out to the existing m32r-sim.h. Unfortunately, we can't yet drop the m32r-sim.h include from sim-main.h as many of the generated CGEN files refer only to sim-main.h. We'll have to improve the CGEN interface before we can make more progress, but this is at least a minor improvement.
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 Frysinger2-1/+2
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.
2022-12-22sim: m32r: include sim-hw.h for sim_hw_parseMike Frysinger1-0/+1
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: m32r: invert sim_cpu storageMike Frysinger5-14/+10
The cpu*.h changes are in generated cgen code, but that has been sent upstream too, so the next regen should include it automatically.
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.
