2020-08-13[ARM, sim] Fix build failure with -Werror (PR26365)Luis Machado2-12/+38
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.

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.

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.

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: use libiberty countargv in more placesMike Frysinger2-6/+6
A bunch of places open code the countargv implementation, or outright duplicate it (as count_argc). Replace all of those w/countargv.
2016-01-03sim: drop host endian configure optionMike Frysinger3-261/+232
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 Frysinger3-18/+23
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.
2016-01-01GDB copyright headers update after running GDB's copyright.py script.Joel Brobecker6-6/+6
gdb/ChangeLog: Update year range in copyright notice of all files.
2015-12-30sim: arm/d10v/h8300/m68hc11/microblaze/mips/mn10300/moxie/sh/v850: convert ↵Mike Frysinger2-10/+14
to common sim_{fetch,store}_register
2015-12-27sim: unify sim-hloadMike Frysinger2-1/+4
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.
2015-12-25sim: arm: delete unused codeMike Frysinger23-3651/+34
These vestiges of the 20 year old emulator are just getting in the way. Punt all the dead code we either don't compile or don't use.
2015-12-15Fix invalid left shift of negative valueDominik Vogt3-28/+33
Fix occurrences of left-shifting negative constants in C code. sim/arm/ChangeLog: * thumbemu.c (handle_T2_insn): Fix left shift of negative value. * armemu.c (handle_v6_insn): Likewise. sim/avr/ChangeLog: * interp.c (sign_ext): Fix left shift of negative value. sim/mips/ChangeLog: * micromips.igen (process_isa_mode): Fix left shift of negative value. sim/msp430/ChangeLog: * msp430-sim.c (get_op, put_op): Fix left shift of negative value. sim/v850/ChangeLog: * simops.c (v850_bins): Fix left shift of negative value.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger2-7/+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.
