2019-01-01Update copyright year range in all GDB files.Joel Brobecker37-37/+37
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.
2018-12-06sim/opcodes: Allow use of out of tree cgen source directoryAndrew Burgess1-5/+11
When configuring with '--enbale-cgen-maint' the default for both the opcodes/ and sim/ directories is to assume that the cgen source is within the binutils-gdb source tree as binutils-gdb/cgen/. In the old cvs days, this worked well, as cgen was just another sub-module of the single cvs repository and could easily be checked out within the binutils-gdb directory, and managed by cvs in the normal way. Now that binutils-gdb is in git, while cgen is still in cvs, placing the cgen respository within the binutils-gdb tree is more troublesome, and it would be nice if the two tools could be kept separate. Luckily there is already some initial code in the configure.ac files for both opcodes/ and sim/ to support having cgen be located outside of the binutils-gdb tree, however, this was speculative code written imagining a future where cgen would be built and installed to some location. Right now there is no install support for cgen, and so the configure code in opcodes/ and sim/ doesn't really do anything useful. In this commit I repurpose this code to allow binutils-gdb to be configured so that it can make use of a cgen source directory that is outside of the binutils-gdb tree. With this commit applied it is now possible to configure and build binutils-gdb like this: /path/to/binutils-gdb/src/configure --enable-cgen-maint=/path/to/cgen/src/cgen/ make all-opcodes make -C opcodes run-cgen-all Just in case anyone is still using cgen inside the binutils-gdb tree, I have left the default behaviour of '--enable-cgen-maint' (with no parameter) unchanged, that is it looks for the cgen directory as 'binutils-gdb/cgen/'. opcodes/ChangeLog: * configure.ac (enable-cgen-maint): Support passing path to cgen source tree. * configure: Regenerate. sim/ChangeLog: * common/acinclude.m4 (enable-cgen-maint): Support passing path to cgen source tree. * cris/configure: Regenerate. * frv/configure: Regenerate. * iq2000/configure: Regenerate. * lm32/configure: Regenerate. * m32r/configure: Regenerate. * or1k/configure: Regenerate. * sh64/configure: Regenerate.
2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi4-550/+601
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.

2016-01-10sim: move many common settings from CPPFLAGS to config.hMike Frysinger3-68/+124
Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.
2016-01-10sim: drop unused SIM_AC_OPTION_PACKAGESMike Frysinger2-7/+6
This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
2016-01-10sim: allow the environment configure option everywhereMike Frysinger3-23/+27
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: allow the assert configure option everywhereMike Frysinger2-2/+23
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.
2016-01-10sim: drop targ-vals.def->nltvals.def indirectionMike Frysinger2-57/+5
We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.
2016-01-10sim: allow the inline configure option everywhereMike Frysinger3-51/+41
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: drop --enable-sim-{regparm,stdcall} optionsMike Frysinger2-12/+6
These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
2016-01-10sim: drop --enable-sim-cflags optionMike Frysinger2-23/+6
No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.
2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger3-3/+406
The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.

2016-01-04sim: punt x86-specific bswap logicMike Frysinger2-21/+6
The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
2016-01-03sim: parse_args: display getopt error ourselvesMike Frysinger2-3/+5
Fix a long standing todo where we let getopt write directly to stderr when an invalid option is passed. Use the sim io funcs instead as they go through the filtered callbacks that gdb wants.

2016-01-03sim: drop host endian configure optionMike Frysinger4-263/+237
The --enable-sim-hostendian flag was purely so people had an escape route for when cross-compiling. This is because historically, AC_C_BIGENDIAN did not work in those cases. That was fixed a while ago though, so we can require that macro everywhere now and simplify a good bit of code.
2016-01-03sim: convert to bfd_endianMike Frysinger5-23/+30
Rather than re-invent endian defines, as well as maintain our own list of OS & arch-specific includes, punt all that logic in favor of the bfd ones already set up and maintained elsewhere. We already rely on the bfd library, so leveraging the endian aspect should be fine.
2016-01-02sim: iq2000/m32r/lm32/sh64: delete dead option codeMike Frysinger2-8/+4
The iq2000/m32r/sh64 option parsing logic appears to have always been dead. At least iq2000/sh64 are simply copy & paste rot from m32r. The lm32 option parsing hack here hasn't been needed for a while -- this was fixed back in commit 11409fac6b95d71a92848a4499b02d60a4f4c5bb in the common code.
2016-01-02sim: delete dead current_state globalsMike Frysinger2-8/+5
The global current_state handle to the current simulator state is a design idea that was half implemented, but never really cleaned up. The point was to have a global variable pointing to the state so that funcs could more quickly & easily access the state anywhere. We've instead moved in the direction of passing state around everywhere and don't have any intention of moving back. I also can't find any references to gdb using this variable, or to cgen related "dump_regs" functions, both of which were used in the comments related to this code.

Pretty much all targets are using this module already, so add it to the common list of objects. The only oddball out here is cris and that's because it supports loading via an offset for all the phdrs. We drop support for that.
2015-12-26sim: punt WITH_DEVICES & tconfig.h supportMike Frysinger3-6/+6
No arch is using this anymore, and we want all new ports using the hardware framework instead. Punt WITH_DEVICES and the two callbacks device_io_{read,write}_buffer. We can also punt the tconfig.h file as no port is using it anymore. This fixes in-tree builds that get confused by picking up the wrong one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.
2015-12-26sim: standardize sim_create_inferior handling of argv a bit moreMike Frysinger2-4/+13
For targets that process argv in sim_create_inferior, improve the code: - provide more details in the comment - make the check for when to re-init more robust - clean out legacy sim_copy_argv code This will be cleaned up more in the future when we have a common inferior creation function, but at least help new ports get it right until then.
2015-12-25sim: m32r: migrate from WITH_DEVICES to WITH_HWMike Frysinger12-178/+361
The m32r port was using the device framework to handle two devices: the cache and uart registers. Both can be implemented in the newer hardware framework instead which allows us to drop the device logic entirely, as well as delete the tconfig.h file. While creating the new uart device model, I also added support for using stdin to read/write data rather than only supporting sockets. This has been lightly tested as there doesn't appear to be test coverage for the code already. If anyone still cares about this port, then they should (hopefully) file bug reports.
2015-12-25sim: sim-model: build for everyoneMike Frysinger2-1/+4
Rather than include this for some targets, set it up so we can build it all the time via the common code. This makes it easier for targets to opt into it when they're ready, increases build coverage, and allows us to centralize much of the logic. We also get to delete tconfig.h from two more targets -- they were setting WITH_DEVICES to 0 which has the same behavior as not defining it at all. While the SIM_HAVE_MODEL knob is gone, we now have WITH_MODEL_P, but it is only used by the common sim-model code. We use it to declare dummy model lists when the arch hasn't created its own.
2015-12-25sim: move MACH/MODEL types into SIM_xxx namespaceMike Frysinger6-13/+21
The "MACH" and "MODEL" names are a bit generic and collide with symbols used by other sections of code (like h8300's opcodes). Since these are sim-specific types, they really should have a "SIM_" prefix.
2015-12-25sim: move WITH_SCACHE_PBB to sim-main.hMike Frysinger3-5/+10
This helps us break up tconfig.h more. Any file using this define should be pulling in sim-main.h already, so things should continue working.
2015-12-25sim: device_error: puntMike Frysinger2-5/+4
Only four targets implement this function, and three of them do nothing. The 4th merely calls abort. Since calls to this function are followed by calls to sim_hw_abort or sim_io_error, this is largely useless. In the two places where we don't, replace the call with sim_engine_abort. We want to kill off the WITH_DEVICES logic in favor of WITH_HW, so this is a good first step.
2015-12-24sim: make LMA loading the default for all targetsMike Frysinger2-3/+4
Most targets already default to loading code via their LMA, but for a few, this means the default changes from loading VMA to LMA. It's better to have the different targets be consistent, and allows some code clean up.
2015-12-24sim: delete old breakpoint codeMike Frysinger4-33/+8
This code relies on the old sim-break module, but that was deleted in 2003. The module only existed for gdb to tell the sim to set breakpoints on its behalf, but then that logic was abandoned in favor of gdb knowing all about proper breakpoints (since it does already for non-sim targets). Some dead code lived on in the older ports though -- clean it up now.
2015-12-24sim: enable watchpoint module everywhereMike Frysinger2-5/+4
We build & bundle the watchpoint module everywhere, but we don't make the command line flags available by default. A few targets opted in, but most did not. Just enable the flag for everyone. Not all targets will respect the flags (making them nops), but shouldn't be a big deal. This is how we handle other common modules already.
2015-12-24sim: delete SIM_HAVE_MEM_SIZEMike Frysinger2-7/+4
This define isn't used anywhere (doesn't seem to ever have been used by versions committed), so delete the commented out code as it's dead.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger2-2/+6
Now that all arches (for the most part) have moved over, move sim-stop.o, sim-reason.o, and sim-reg.o to the common object list and out of all the arch ports.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger2-9/+4
Other than the nice advantage of all sims having to declare one fewer common function, this also fixes leakage in pretty much every sim. Many were not freeing any resources, and a few were inconsistent as to the ones they did. Now we have a single module that takes care of all the logic for us. Most of the non-cgen based ones could be deleted outright. The cgen ones required adding a callback to the arch-specific cleanup func. The few that still have close callbacks are to manage their internal state. We do not convert erc32, m32c, ppc, rl78, or rx as they do not use the common sim core.
2015-07-24Remove leading/trailing white spaces in ChangeLogH.J. Lu1-14/+14
2015-06-23sim: use AS_HELP_STRING everywhereMike Frysinger2-16/+33
This helps standardize the configure --help output.
2015-06-17sim: syscall: add common sim_syscall helpersMike Frysinger3-43/+35
Many ports have the same sim syscall logic, so add some helpers to handle all the common details. The arches still have to deal with the unpacking and packing of the syscall arguments, but the rest of the sim<->callback glue is now shared.
2015-06-17sim: syscall: unify memory helpersMike Frysinger3-50/+19
Almost every port implements these two callbacks in the same way, so unify them in the common layer.
2015-06-12sim: update configure.in->configure.ac docsMike Frysinger2-1/+5
A few places still refer to the configure.in file; update them.
2015-06-12sim: drop -DTRACE from configureMike Frysinger2-3/+7
No code uses this anymore and the symbol conflicts with the new TRACE helper. Punt it from configure.
2015-06-12sim: cgen: namespace custom trace functionsMike Frysinger9-974/+986
The cgen code declares some macros/funcs using the trace_xxx prefix, but the code isn't generic and only works with cgen targets. This is blocking the creation of new common trace functions. Let's blindly add cgen_xxx prefixes to all these symbols. Some already use this convention to avoid conflicts, so it makes sense to align them. In the future we might want to move some to the common trace core, but one thing at a time.
2015-04-18sim: clean up duplicate sim-engine hooksMike Frysinger2-11/+4
Now that we've unified sim-cpu, we can delete the duplicate sim-engine hooks -- these targets defined these only because they didn't fully implement the sim-cpu callbacks.
2015-04-18sim: trim old USING_SIM_BASE_H defineMike Frysinger2-2/+4
This doesn't appear to have been used since 1998, but wasn't cleaned up since. So much for being "quick" ;).
2015-04-18sim: unify SIM_CPU definitionMike Frysinger2-3/+4
Since every target typedefs this the same way, move it to the common code. We have to leave Blackfin behind here for now because of inter-dependencies on types and headers: sim-base.h includes sim-model.h which needs types in machs.h which needs types in bfim-sim.h which needs SIM_CPU.
