2021-05-17sim: fully merge sim_state_base into sim_stateMike Frysinger2-2/+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 Frysinger2-7/+7
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 Frysinger12-3/+37
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 Frysinger3-2/+19
2021-05-14sim: callback: convert time interface to 64-bitMike Frysinger2-3/+7
PR sim/27705 Rather than rely on time_t being the right size between the host & target, have the interface always be 64-bit. We can figure out if we need to truncate when actually outputting it to the right target.
2021-05-14sim: create header namespaceMike Frysinger3-3/+8
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 Frysinger2-2/+14
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.
2021-05-03sim: add ATTRIBUTE_PRINTF / ATTRIBUTE_NULL_PRINTF where necessarySimon Marchi3-3/+10
I finally got the all-targets sim building with Clang, these are all the instances where an ATTRIBUTE_PRINTF or ATTRIBUTE_NULL_PRINTF attribute needed to be added to avoid errors like: /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-profile.c:464:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral] vfprintf (fp, fmt, ap); ^~~ There are more fixes needed to get everything building, but adding these attributes is trivial enough, so I send them all in a single patch. Adding the format attributes introduces some format string errors when building with GCC (because now format strings are checked), so corresponding changes are needed to avoid breaking the build. Other than simple format string specified changes, there is this one: /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c: In function 'hw_event_queue_schedule': /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c:95:15: error: too many arguments for format [-Werror=format-extra-args] 95 | NULL, dummy); | ^~~~~ We can fix it and avoid using a dummy variable by simply calling hw_event_queue_schedule_tracef instead of hw_event_queue_schedule_vtracef. sim/arm/ChangeLog: * armdefs.h (ARMul_ConsolePrint): Use format attribute. * wrapper.c (op_printf): Likewise. sim/bfin/ChangeLog: * interp.c (sim_open): Adjust format string specifier. sim/common/ChangeLog: * hw-events.h (hw_event_queue_schedule_tracef): Use format attribute.

2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger3-2/+12
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.
2021-05-01sim: arm: move build logic to source filesMike Frysinger3-9/+25
This simplifies the build logic a bit by just having source file inputs. It also simplifies code that assumes there's a source file for each object.
2021-04-26sim: enable hardware support by defaultMike Frysinger4-5/+120
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 Tromey3-14/+6
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 Tromey2-4/+11
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.

2021-04-21sim: use -Werror when probing for supported warning flagsSimon Marchi2-1/+5
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 Frysinger1-52/+47
This avoids duplicate tests for headers between common m4, arches, and any other sources that would trigger header tests.
2021-04-18sim: switch to AC_CHECK_FUNCS_ONCE & merge a littleMike Frysinger2-25/+52
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 Frysinger2-1/+5
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 Frysinger3-153/+162
The toplevel, common, and igen dirs all have their own code for setting up toolchain settings. Unify all of that in a new macro.
2021-02-28sim: set up build-time compiler settingsMike Frysinger1-9/+10
Some sim dirs were already setting up CFLAGS_FOR_BUILD in inconsistent ways. Move it to a common place for reuse.
2021-02-28sim: use AC_CHECK_TOOL to find arMike Frysinger1-3/+93
Rather than require $AR be set and then default to `ar`, use the standard AC_CHECK_TOOL helper to find a good prefixed tool. In practice this shouldn't change much as we seem to have macros in the tree that were already setting it up, but we shouldn't rely on that implicitly.
2021-02-28sim: require AC_PROG_CPP explicitlyMike Frysinger2-142/+145
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 Frysinger4-11/+34
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 Frysinger4-1834/+35
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: common: switch AC_CONFIG_HEADERSMike Frysinger1-3/+2
The AC_CONFIG_HEADER macro is long deprecated, so switch to the newer form. This also gets rid of the position limitation, and drops support for an argument to SIM_AC_COMMON which we haven't used anywhere.
2021-02-06sim: drop use of bfd/configure.hostMike Frysinger2-7/+15
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 Frysinger3-16/+35
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 Frysinger1-14/+3
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 Frysinger2-5/+7
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 Frysinger2-13/+57
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.

There is a bit of a situation in the ARM sim with regards to the handling of argv. sim_open () gets a const char **argv, but ARM's sim_open gets clever and decides to modify argv in place via sim_target_parse_command_line. I'm not sure why. In any case, here's a fix that makes the code modify a copy of argv instead. sim/arm/ChangeLog: 2020-08-13 Luis Machado <luis.machado@linaro.org> PR sim/26365 * wrapper.c (sim_target_parse_command_line): Free discarded argv entries.

Newer GCC's have switched to -fno-common by default, and this breaks the build for the ARM sim, like this: binutils-gdb.git~gdb-8.3-release/sim/arm/maverick.c:65: multiple definition of `DSPsc'; libsim.a(wrapper.o):binutils-gdb.git~gdb-8.3-release/sim/arm/wrapper.c:134: first defined here binutils-gdb.git~gdb-8.3-release/sim/arm/maverick.c:64: multiple definition of `DSPacc'; libsim.a(wrapper.o):binutils-gdb.git~gdb-8.3-release/sim/arm/wrapper.c:133: first defined here binutils-gdb.git~gdb-8.3-release/sim/arm/maverick.c:63: multiple definition of `DSPregs'; libsim.a(wrapper.o):binutils-gdb.git~gdb-8.3-release/sim/arm/wrapper.c:132: first defined here I also noticed a few warnings due to mismatching types, as follows: ../../../../repos/binutils-gdb/sim/arm/wrapper.c: In function ‘sim_create_inferior’: ../../../../repos/binutils-gdb/sim/arm/wrapper.c:335:16: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] for (arg = argv; *arg != NULL; arg++) ^ ../../../../repos/binutils-gdb/sim/arm/wrapper.c:342:8: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] arg = argv; ^ ../../../../repos/binutils-gdb/sim/arm/wrapper.c:345:13: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] for (arg = argv; *arg != NULL; arg++) ^ The following patch fixes both of the above. sim/arm/ChangeLog: 2019-12-06 Luis Machado <luis.machado@linaro.org> * armemu.c (isize): Move this declaration ... * arminit.c (isize): ... here. * maverick.h: New file. * wrapper.c: Include "maverick.h".

2019-01-01Update copyright year range in all GDB files.Joel Brobecker6-6/+6
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi4-547/+598
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see: configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation Solution 1: Adjust the code based on the example at that URL. Problem 2 (in zlib/): Makefile.am: error: required file './INSTALL' not found Makefile.am: 'automake --add-missing' can install 'INSTALL' Makefile.am: error: required file './NEWS' not found Makefile.am: error: required file './AUTHORS' not found Makefile.am: error: required file './COPYING' not found Makefile.am: 'automake --add-missing' can install 'COPYING' Solution 2: Add the foreign option to AUTOMAKE_OPTIONS. Problem 3: doc/Makefile.am:20: error: support for Cygnus-style trees has been removed Solution 3: Remove the cygnus options. Problem 4: Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') Solution 4: Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is already defined earlier). Problem 5: doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 5: Rename .texinfo files to .texi. Problem 6: doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 6: Remove the hack at the bottom of doc/Makefile.am and use the info-in-builddir automake option. Problem 7: doc/Makefile.am:35: error: required file '../texinfo.tex' not found doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex' Solution 7: Use the no-texinfo.tex automake option. We also have one in texinfo/texinfo.tex, not sure if we should point to that, or move it (or a newer version of it added with automake --add-missing) to top-level. Problem 8: Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory, Makefile.am:131: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. Solution 8: Use subdir-objects, that means adjusting references to some .o that will now be in config/. Problem 9: configure.ac:375: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from... ../../lib/autoconf/general.m4:2601: _AC_COMPILE_IFELSE is expanded from... ../../lib/autoconf/general.m4:2617: AC_COMPILE_IFELSE is expanded from... ../../lib/m4sugar/m4sh.m4:639: AS_IF is expanded from... ../../lib/autoconf/general.m4:2042: AC_CACHE_VAL is expanded from... ../../lib/autoconf/general.m4:2063: AC_CACHE_CHECK is expanded from... configure.ac:375: the top level Solution 9: Use AC_LANG_SOURCE, or use proper quoting. Problem 10 (in intl/): configure.ac:7: warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS /usr/share/aclocal/threadlib.m4:36: gl_THREADLIB_EARLY_BODY is expanded from... /usr/share/aclocal/threadlib.m4:29: gl_THREADLIB_EARLY is expanded from... /usr/share/aclocal/threadlib.m4:318: gl_THREADLIB is expanded from... /usr/share/aclocal/lock.m4:9: gl_LOCK is expanded from... /usr/share/aclocal/intl.m4:211: gt_INTL_SUBDIR_CORE is expanded from... /usr/share/aclocal/intl.m4:25: AM_INTL_SUBDIR is expanded from... /usr/share/aclocal/gettext.m4:57: AM_GNU_GETTEXT is expanded from... configure.ac:7: the top level Solution 10: Add AC_USE_SYSTEM_EXTENSIONS in configure.ac.
