2020-12-02Add gnu global outputs to .gitignoreEnze Li1-0/+4
GNU Global outputs can be safely ignored. ChangeLog: 2020-12-02 Enze Li <lienze2010@hotmail.com> * .gitignore: Add gnu global outputs. Change-Id: I04ce68ab3279426195793adb56f834a34ee72ea2

Bring in a few lines that are in gcc's .gitignore but not binutils-gdb's .gitignore. ChangeLog: * .gitignore: Sync with gcc. Change-Id: I8900ddfbb5ab8cce6236e1905fdbb52fb4c291e2
2020-10-28Use sha256 for hashes in the release processAndreas Rammhold1-0/+4
I just came across the GDB 10.1 release notes and saw that md5 is still being used in those. I thought it would be a good idea to instead have a more modern, secure and wildly available hash function such as SHA256 as part of the release process. The changes have been done rather mechnically via sed but executing the `src-release.sh -b gdb` did work so I am confident about the result. While this does not directly address the release mails, I was wasn't able to find the template/script used for those, this is probably still an improvement. ChangeLog: * src-release.sh: Use sha256sum instead of md5sum. binutils/ChangeLog: * README-how-to-make-a-release: Use sha256sum instead of md5sum. Change-Id: I9cf19ea40699137c45463b8514f6e29271af2347
2020-10-14gdb/gdbserver: add dependencies for distclean-gnulibAndrew Burgess1-0/+6
After commit: commit 361cb219351d8b7e39e1962fe77f40aa80657b27 Date: Tue Oct 6 10:09:06 2020 +0100 gnulib: Ensure all libraries are used when building gdb/gdbserver We now get an error when, at the top level of the build tree, we do 'make distclean'. The reason for this is that the gnulib directory is cleaned before the gdb directory, cleaning gnulib deletes Makefile.gnulib.inc from the gnulib build directory, which is currently pulled in by the gdb Makefile.in using 'include'. This commit adds a dependency between distclean-gnulib and both distclean-gdb and distclean-gdbserver. This means that gdb and gdbserver will be cleaned before gnulib, as a result the Makefile.gnulib.inc file should exist when needed. ChangeLog: * Makefile.in: Rebuild. * Makefile.def: Make distclean-gnulib depend on distclean-gdb and distclean-gdbserver.

2020-03-12Change gdbserver to use existing gdbsupportTom Tromey1-0/+5
This changes the gdbserver build to use the gdbsupport that was built for gdb. gdbserver and gdbreplay now must use WIN32APILIBS (aka -lws2_32). Before this change, gdbserver did not define USE_WIN32API when building gdbsupport, but now this is always done. ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def (gdbserver): Depend on gdbsupport. gdbserver/ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac (GDBSERVER_DEPFILES): Remove srv_selftest_objs.

2020-03-12Change gdbsupport not to rely on BFDTom Tromey1-0/+5
This changes gdbsupport so that it no longer relies on BFD. This is a precursor to making gdbserver use the already-built gdbsupport, because building gdbserver should not require BFD to be built. The most notable change here is that CORE_ADDR is always a 64-bit type. This makes it so that gdb acts as if it were always built in 64-bit mode. ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def (gdbsupport): Don't depend on bfd. gdbsupport/ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * common-types.h: Remove GDBSERVER code.

2020-03-12Fix gdbserver build when intl already builtTom Tromey1-0/+5
gdbserver uses gdb's alloc.c, and this in turn can include headers from intl via gdbsupport/gdb_locale.h. This can cause build failures in some situations, for example if you build gdb and gdbserver on mingw. This patch restores the gdbsupport dependency on intl, and changes gdbserver to use ZW_GNU_GETTEXT_SISTER_DIR. This fixes this build problem. ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def (gdbsupport): Depend on intl. gdbserver/ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * config.in, configure: Rebuild. * configure.ac: Call ZW_GNU_GETTEXT_SISTER_DIR. * acinclude.m4: Include gettext-sister.m4. * Makefile.in (top_builddir, INTL, INTL_DEPS, INTL_CFLAGS): New variables. (INCLUDE_CFLAGS): Add INTL_CFLAGS. (gdbserver$(EXEEXT), gdbreplay$(EXEEXT)): Use INTL_DEPS, INTL.
2020-02-17Fix gdbserver-without-gdb buildTom Tromey1-0/+6
An earlier patch changed gdbserver to use the already-built top-level gnulib and gdbsupport. However, if one did a build that did not include gdb, then gdbserver would fail to build. The problem is that configure.ac only adds gnulib and gdbsupport to the build when gdb is being built. This patch fixes the problem by arranging for this to happen when gdbserver is built. ChangeLog 2020-02-17 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac (configdirs): Add gnulib and gdbsupport when building gdbserver.
2020-02-14Change gdbserver to use existing gnulib and libibertyTom Tromey1-0/+5
This changes gdbserver so that it no longer builds its own gnulib and libiberty. Instead, it now relies on the ones that were already built at the top level. gdbsupport is still built specially for gdbserver. This is more complicated and will be tackled in a subsequent patch. ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def: Make gdbserver require gnulib and libiberty. gdbserver/ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * acinclude.m4: Don't include acx_configure_dir.m4. * Makefile.in (LIBIBERTY_BUILDDIR, GNULIB_BUILDDIR): Update.

2020-02-07Move gdbserver to top levelTom Tromey1-0/+11
This patch moves gdbserver to the top level. This patch is as close to a pure move as possible -- gdbserver still builds its own variant of gnulib and gdbsupport. Changing this will be done in a separate patch. [v2] Note that, per Simon's review comment, this patch changes the tree so that gdbserver is not built for or1k or score. This makes sense, because there is apparently not actually a gdbserver port here. [v3] This version of the patch also splits out some configury into a new file, gdbserver/configure.host, so that the top-level configure script can simply rely on it in order to decide whether gdbserver should be built. [v4] This version adds documentation and removes some unnecessary top-level dependencies. [v5] Update docs to mention "make all-gdbserver" and change how top-level configure decides whether to build gdbserver, switching to a single, shared script. Tested by the buildbot. ChangeLog 2020-02-07 Tom Tromey <tom@tromey.com> Pedro Alves <palves@redhat.com> * src-release.sh (GDB_SUPPORT_DIRS): Add gdbserver. * gdbserver: New directory, moved from gdb/gdbserver. * configure.ac (host_tools): Add gdbserver.

2020-01-29Adjust src-release.sh's getver due to gdbsupport's move to toplevelSergio Durigan Junior1-0/+6
The move of gdbsupport to the top level directory requires a small change to src-release.sh's "getver" function, which is responsible for determining the version string that will be appended to the release tarball: now the create-version.sh script lives under ./gdbsupport, and not under gdb/gdbsupport anymore. This patch unbreaks the snapshot generation, which hasn't been working since January 14th. ChangeLog: 2020-01-29 Sergio Durigan Junior <sergiodj@redhat.com> * src-release.sh (getver): Look for gdbsupport's create-version.sh script at the current directory if tool is "gdb".

2020-01-19sim: don't rely on inferior_ptid in gdbsim_target::waitSimon Marchi1-0/+5
When running a program with the simulator target, I get: /home/simark/src/binutils-gdb/gdb/inferior.c:279: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed. This can be reproduced by building a GDB for --target=arm-none-gnueabi, and running with $ ./gdb -nx --data-directory=data-directory a.out -ex "target sim" -ex load -ex "b main" -ex r Where a.out is any program with a main. The problem is that gdbsim_target::wait assumes that inferior_ptid has the value of the thread it wants to report an event for. Actually, it's the target's responsibility to come up with the ptid of the thread the event is for. In the sim target, that ptid is stored in sim_inferior_data::remote_sim_ptid, so return that instead of inferior_ptid. ChangeLog: * remote-sim.c (gdbsim_target::wait): Return sim_data->remote_sim_ptid instead of inferior_ptid.

2020-01-14Move gdbsupport to the top levelTom Tromey1-0/+10
This patch moves the gdbsupport directory to the top level. This is the next step in the ongoing project to move gdbserver to the top level. The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport". This patch then adds a build system to gdbsupport and wires it into the top level. Then it changes gdb to use the top-level build. gdbserver, on the other hand, is not yet changed. It still does its own build of gdbsupport.

2019-10-03libctf: installable libctf as a shared libraryNick Alcock1-0/+5
This lets other programs read and write CTF-format data. Two versioned shared libraries are created: libctf.so and libctf-nobfd.so. They contain identical content except that libctf-nobfd.so contains no references to libbfd and does not implement ctf_open, ctf_fdopen, ctf_bfdopen or ctf_bfdopen_ctfsect, so it can be used by programs that cannot use BFD, like readelf. The soname major version is presently .0 until the linker API stabilizes, when it will flip to .1 and hopefully never change again. New in v3. v4: libtoolize and turn into a pair of shared libraries. Drop --enable-install-ctf: now controlled by --enable-shared and --enable-install-libbfd, like everything else. v5: Add ../bfd to ACLOCAL_AMFLAGS and AC_CONFIG_MACRO_DIR. Fix tabdamage. * Makefile.def (host_modules): libctf is no longer no_install. * Makefile.in: Regenerated. libctf/ * configure.ac (AC_DISABLE_SHARED): New, like opcodes/. (LT_INIT): Likewise.

2019-10-03bfd, ld: add CTF section linkingNick Alcock1-0/+5
This is quite complicated because the CTF section's contents depend on the final contents of the symtab and strtab, because it has two sections whose contents are shuffled to be in 1:1 correspondence with the symtab, and an internal strtab that gets deduplicated against the ELF strtab (with offsets adjusted to point into the ELF strtab instead). It is also compressed if large enough, so its size depends on its contents! So we cannot construct it as early as most sections: we cannot even *begin* construction until after the symtab and strtab are finalized. Thankfully there is already one section treated similarly: compressed debugging sections: the only differences are that compressed debugging sections have extra handling to deal with their changing name if compressed (CTF sections are always called ".ctf" for now, though we have reserved ".ctf.*" against future use), and that compressed debugging sections have previously-uncompressed content which has to be stashed away for later compression, while CTF sections have no content at all until we generate it (very late). BFD also cannot do the link itself: libctf knows how to do it, and BFD cannot call libctf directly because libctf already depends on bfd for file I/O. So we have to use a pair of callbacks, one, examine_strtab, which allows a caller to examine the symtab and strtab after finalization (called from elf_link_swap_symbols_out(), right before the symtabs are written, and after the strtab has been finalized), and one which actually does the emission (called emit_ctf simply because it is grouped with a bunch of section-specific late-emission function calls at the bottom of bfd_elf_final_link, and a section-specific name seems best for that). emit_ctf is actually called *twice*: once from lang_process if the emulation suggests that this bfd target does not examine the symtab or strtab, and once via a bfd callback if it does. (This means that non-ELF targets still get CTF emitted, even though the late CTF emission stage is never called for them). v2: merged with non-ELF support patch: slight commit message adjustments. v3: do not spend time merging CTF, or crash, if the CTF section is explicitly discarded. Do not try to merge or compress CTF unless linking. v4: add CTF_COMPRESSION_THRESHOLD. Annul the freed input ctf_file_t's after writeout: set SEC_IN_MEMORY on the output contents so a future bfd enhancement knows it could free it. Add SEC_LINKER_CREATED | SEC_KEEP to avoid having to add .ctf to the linker script. Drop now-unnecessary ldlang.h-level elf-bfd.h include and hackery around it. Adapt to elf32.em->elf.em and elf-generic.em->ldelf*.c changes. v5: fix tabdamage. Drop #inclusions in .h files: include in .c files, .em files, and use struct forwards instead. Use bfd_section_is_ctf inline function rather than SECTION_IS_CTF macro.

2019-08-19Add --with-static-standard-libraries to the top levelTom Tromey1-0/+5
gdb should normally not be linked with -static-libstdc++. Currently this has not caused problems, but it's incompatible with catching an exception thrown from a shared library -- and a subsequent patch changes gdb to do just this. This patch adds a new --with-static-standard-libraries flag to the top-level configure. It defaults to "auto", which means enabled if gcc is being built, and disabled otherwise.

2019-07-13adjust src-release following the renaming of gdb/common/ to gdb/gdbsupport/Joel Brobecker1-0/+5
A recent change renamed the common/ directory into gdbsupport/ in gdb. This causes problems in the getver function in the src-release script which doesn't find the create-version.sh script anymore. As a result, it falls back on using the version.in file verbatim, meaning that the "DATE" placeholder doesn't get replaced with the snapshot date, and the "-git" suffix doesn't get stripped. More precisely, we get snapshots called "gdb-8.3.50-DATE-git.tar" instead of (e.g.) "gdb-8.3-20190712.tar". This commit fixes the issue by adding support for this situation. I left the support for $tool/common/create-version.sh, because the sim still uses that directory structure. ChangeLog: * src-release (getver): If $tool/gdbsupport/create-version.sh exists, use that to determine the version number.

2019-06-14Move gnulib to top levelTom Tromey1-0/+9
This patch moves the gdb/gnulib subdirectory to the top level. It adjusts the top-level build system to build gnulib when necessary, and changes gdb to use this. However, gdbserver still builds its own copy of gnulib, just from the new source location. A small hack was needed to ensure that gnulib is only built when gdb is enabled. The Makefile only provides an ordering -- the directory must be mentioned in configdirs to actually be compiled at all. Most of the patch is just a "git mv" of gnulib, though a few minor path adjustments were needed in some files there. Tested by the buildbot.
