2022-09-26binutils, gdb: support zstd compressed debug sectionsFangrui Song1-0/+3
PR29397 PR29563: Add new configure option --with-zstd which defaults to auto. If pkgconfig/libzstd.pc is found, define HAVE_ZSTD and support zstd compressed debug sections for most tools. * bfd: for addr2line, objdump --dwarf, gdb, etc * gas: support --compress-debug-sections=zstd * ld: support ELFCOMPRESS_ZSTD input and --compress-debug-sections=zstd * objcopy: support ELFCOMPRESS_ZSTD input for --decompress-debug-sections and --compress-debug-sections=zstd * gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd symbols, so gdb has to link against -lzstd in this patch. If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this is too heavyweight, so don't do it for now. ``` % ld/ld-new a.o ld/ld-new: a.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... % ld/ld-new a.o --compress-debug-sections=zstd ld/ld-new: --compress-debug-sections=zstd: ld is not built with zstd support % binutils/objcopy --compress-debug-sections=zstd a.o b.o binutils/objcopy: --compress-debug-sections=zstd: binutils is not built with zstd support % binutils/objcopy b.o --decompress-debug-sections binutils/objcopy: zstd.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... ```

2022-05-26ld: add --package-metadataLuca Boccassi1-0/+3
Generate a .note.package FDO package metadata ELF note, following the spec: https://systemd.io/ELF_PACKAGE_METADATA/ If the jansson library is available at build time (and it is explicitly enabled), link ld to it, and use it to validate that the input is correct JSON, to avoid writing garbage to the file. The configure option --enable-jansson has to be used to explicitly enable it (error out when not found). This allows bootstrappers (or others who are not interested) to seamlessly skip it without issues.

2020-06-26binutils, ld: work with --disable-libctfNick Alcock1-0/+3
This unfortunately means conditionalizing out all the libctf code, but the result is not too unbearably ugly, if a bit repetitive. I have stubbed out code in the !ENABLE_LIBCTF path to avoid extra redundant ifdefs where it seems that might be helpful. (The stubs are not too disruptive, but I've tried to keep them on one line where possible to avoid filling up the screen with stubs that nobody would care about. If this is too much of a coding style violation I can change it.)

2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi1-0/+5
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/.

2018-02-27ld: Add --enable-separate-codeH.J. Lu1-0/+4
This patch adds --enable-separate-code to ld configure to turn on -z separate-code by default and enables it by default for Linux/x86.

2014-08-14configury changes to make ld plugin support controlled by --enable-pluginsAlan Modra1-9/+0
This also makes --enable-plugins default to on for hosts that can support plugins, so we have consistent lto toolchain support. The ACX_LARGEFILE moves aren't strictly necessary, but are harmless and will be necessary if plugin support is extended to more hosts via libtool's dlopen support. I started down that path then decided it was more work than I was interested in doing. (ACX_LARGEFILE invokes AC_PLUGINS.) config/ * plugins.m4: Test for dlfcn.h or windows.h here to set default for --enable-plugins.
