2024-02-05Fix disabling of year 2038 support on 32-bit hosts by defaultThiago Jung Bauermann1-1/+2
Commit e5f2f7d901ee ("Disable year 2038 support on 32-bit hosts by default") fixed a mismatch between 64-bit time_t in GDB and system headers and 32-bit time_t in BFD. However, since commit 862776f26a59 ("Finalized intl-update patches") gnulib's year 2038 support has been accidentally re-enabled — causing problems for 32-bit hosts again. The commit split baseargs into {h,b}baseargs, but this hasn't been done for the code that handles --disable-year2038. This patch restores the intended behaviour. With this change, the number of unexpected core files goes from 18 to 4. Tested on armv8l-linux-gnueabihf. Approved-By: Luis Machado <luis.machado@arm.com>
2024-01-10Sync top level configure and makefilesNick Clifton1-1/+33
This update brings in the following commits from the gcc mainline: commit b7e5a29602143b53267efcd9c8d5ecc78cd5a62f Author: Tom Tromey <tom@tromey.com> Date: Tue Jan 9 06:25:26 2024 -0700 Pass GUILE down to subdirectories When I enable cgen rebuilding in the binutils-gdb tree, the default is to run cgen using 'guile'. However, on my host, guile is guile 2.2, which doesn't work for me -- I have to use guile3.0. This patch arranges to pass "GUILE" down to subdirectories, so I can use 'make GUILE=guile3.0'. commit 725fb3595622a4ad8cd078a42fab1c395cbf90cb Author: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com> Date: Wed Oct 25 13:06:48 2023 +0200 build: Add libgrust as compilation modules Define the libgrust directory as a host compilation module as well as for targets.

That will spawn two independent make processes inside the "gcc" directory, and each of those will attempt to create site.exp if it doesn't exist and will interfere with each other, producing often a corrupted or empty site.exp. Resolve that by making these targets depend on a new phony target which makes sure site.exp is created first before starting the recursive makes. commit 6a6d3817afa02bbcd2388c8e005da6faf88932f1 Author: Iain Sandoe <iain@sandoe.co.uk> Date: Sun Mar 28 14:48:17 2021 +0100 Config,Darwin: Allow for configuring Darwin to use embedded runpath. Recent Darwin versions place contraints on the use of run paths specified in environment variables. This breaks some assumptions in the GCC build. This change allows the user to configure a Darwin build to use '@rpath/libraryname.dylib' in library names and then to add an embedded runpath to executables (and libraries with dependents). The embedded runpath is added by default unless the user adds '-nodefaultrpaths' to the link line. For an installed compiler, it means that any executable built with that compiler will reference the runtimes installed with the compiler (equivalent to hard-coding the library path into the name of the library). During build-time configurations any "-B" entries will be added to the runpath thus the newly-built libraries will be found by exes. Since the install name is set in libtool, that decision needs to be available here (but might also cause dependent ones in Makefiles, so we need to export a conditional). This facility is not available for Darwin 8 or earlier, however the existing environment variable runpath does work there. We default this on for systems where the external DYLD_LIBRARY_PATH does not work and off for Darwin 8 or earlier. For systems that can use either method, if the value is unset, we use the default (which is currently DYLD_LIBRARY_PATH). commit 2551e10038a70901f30b2168e6e3af4536748f3c Author: Sergei Trofimovich <siarheit@google.com> Date: Mon Oct 2 12:08:17 2023 +0100 Makefile.tpl: disable -Werror for feedback stage [PR111663] Without the change profiled bootstrap fails for various warnings on master branch as: $ ../gcc/configure $ make profiledbootstrap ... gcc/genmodes.cc: In function ‘int main(int, char**)’: gcc/genmodes.cc:2152:1: error: ‘gcc/build/genmodes.gcda’ profile count data file not found [-Werror=missing-profile] ... gcc/gengtype-parse.cc: In function ‘void parse_error(const char*, ...)’: gcc/gengtype-parse.cc:142:21: error: ‘%s’ directive argument is null [-Werror=format-overflow=] The change removes -Werror just like autofeedback does today. commit d1bff1ba4d470f6723be83c0e3c4d5083e51877a Author: Thomas Schwinge <thomas@codesourcery.com> Date: Thu Jun 1 23:07:37 2023 +0200 Pass 'SYSROOT_CFLAGS_FOR_TARGET' down to target libraries [PR109951] ..., where we need to use it (separate commits) for build-tree testing, similar to 'gcc/Makefile.in:site.exp': # TEST_ALWAYS_FLAGS are flags that should be passed to every compilation. # They are passed first to allow individual tests to override them. @echo "set TEST_ALWAYS_FLAGS \"$(SYSROOT_CFLAGS_FOR_TARGET)\"" >> ./site.tmp PR testsuite/109951 * Makefile.tpl (BASE_TARGET_EXPORTS): Add 'SYSROOT_CFLAGS_FOR_TARGET'. * Makefile.in: Regenerate.

2023-08-12configure, Darwin: Ensure overrides to host-pie are passed to gcc configure.Iain Sandoe1-12/+32
The latest versions of Darwin on the Aarch64 platform mandate PIE executables. On x86_64 it remains optional, but produces tool warnings after Darwin20, so we default to PIE executables there too. All (non-PowerPC) 64b Darwin platforms mandate PIC code and therefore force host_shared on (we issue a diagnostic if the user tries to configure them non-shared). However, this also means we cannot test the host_shared setting independently of the host_pie setting so that the logic for setting PICFLAG must be amended for Darwin. For Darwin versions required to have PIE executables, in the event that the user tries to configure these as --disable-host-pie, we issue a warning and override the setting. These versions must also switch host_pie on even if it is not given in the configure line. To cater for this we pass the current value of host_pie, as determined by top-level configure, to the GCC configure. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> * Makefile.def: Pass the enable-host-pie value to GCC configure. * configure.ac: Adjust the logic for shared and PIE host flags to ensure that PIE is passed for hosts that require it.

2023-08-12configure: Implement --enable-host-pieMarek Polacek1-2/+41
This patch implements the --enable-host-pie configure option which makes the compiler executables PIE. This can be used to enhance protection against ROP attacks, and can be viewed as part of a wider trend to harden binaries.

2023-01-06configure: remove dependencies on gmp and mpfr when gdb is disabledClément Chigot1-1/+3
Since 991180627851801f1999d1ebbc0e569a17e47c74, the configure checks about GMP and MPFR for gdb builds have been moved to the toplevel configure. However, it doesn't take into account the --disable-gdb option. Meaning that a build without gdb will require these libraries even if not needed. ChangeLog: * configure.ac: Skip GMP and MPFR when --disable-gdb is provided. * configure: Regenerate.
2022-12-21Use toplevel configure for GMP and MPFR for gdbAndrew Pinski1-7/+38
This patch uses the toplevel configure parts for GMP/MPFR for gdb. The only thing is that gdb now requires MPFR for building. Before it was a recommended but not required library. Also this allows building of GMP and MPFR with the toplevel directory just like how it is done for GCC. We now error out in the toplevel configure of the version of GMP and MPFR that is wrong. OK after GDB 13 branches? Build gdb 3 ways: with GMP and MPFR in the toplevel (static library used at that point for both) With only MPFR in the toplevel (GMP distro library used and MPFR built from source) With neither GMP and MPFR in the toplevel (distro libraries used) Changes from v1: * Updated gdb/README and gdb/doc/gdb.texinfo. * Regenerated using unmodified autoconf-2.69 Thanks, Andrew Pinski ChangeLog: * Makefile.def: Add configure-gdb dependencies on all-gmp and all-mpfr. * configure.ac: Split out MPC checking from MPFR.

2022-11-15libsframe: add the SFrame libraryWeimin Pan1-1/+1
libsframe is a library that allows you to: - decode a .sframe section - probe and inspect a .sframe section - encode (and eventually write) a .sframe section. This library is currently being used by the linker, readelf, objdump. This library will also be used by the SFrame unwinder which is still to be upstream'd. The file include/sframe-api.h defines the user-facing APIs for decoding, encoding and probing .sframe sections. A set of error codes together with their error message strings are also defined. Endian flipping is performed automatically at read and write time, if cross-endianness is detected. ChangeLog: * Makefile.def: Add libsframe as new module with its dependencies. * Makefile.in: Regenerated. * binutils/Makefile.am: Add libsframe. * binutils/Makefile.in: Regenerated. * configure: Regenerated * configure.ac: Add libsframe to host_libs. * libsframe/Makefile.am: New file. * libsframe/Makefile.in: New file. * libsframe/aclocal.m4: New file. * libsframe/config.h.in: New file. * libsframe/configure: New file. * libsframe/configure.ac: New file. * libsframe/sframe-error.c: New file. * libsframe/sframe-impl.h: New file. * libsframe/sframe.c: New file. include/ChangeLog: * sframe-api.h: New file. testsuite/ChangeLog: * libsframe/testsuite/Makefile.am: New file. * libsframe/testsuite/Makefile.in: Regenerated. * libsframe/testsuite/libsframe.decode/Makefile.am: New file. * libsframe/testsuite/libsframe.decode/Makefile.in: Regenerated. * libsframe/testsuite/libsframe.decode/decode.exp: New file. * libsframe/testsuite/libsframe.encode/Makefile.am: Likewise. * libsframe/testsuite/libsframe.encode/Makefile.in: Regenerated. * libsframe/testsuite/libsframe.encode/encode.exp: New file. * libsframe/testsuite/libsframe.encode/encode-1.c: Likewise. * libsframe/testsuite/libsframe.decode/be-flipping.c: Likewise. * libsframe/testsuite/libsframe.decode/frecnt-1.c: Likewise. * libsframe/testsuite/libsframe.decode/frecnt-2.c: Likewise. * libsframe/testsuite/libsframe.decode/DATA-BE: New file. * libsframe/testsuite/libsframe.decode/DATA1: Likewise. * libsframe/testsuite/libsframe.decode/DATA2: Likewise.

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 ... ```
2022-09-21configure: Pass CPPFLAGS_FOR_BUILD to subdirsTsukasa OI1-0/+2
Because CPPFLAGS_FOR_BUILD is used in some subdirectories (through bfd/warning.m4), not AC_SUBSTing the variable causes minor issues. Fortunately, it didn't cause severe errors but error messages related to @CPPFLAGS_FOR_BUILD@ (not AC_SUBSTed CPPFLAGS_FOR_BUILD variable passed to subdirectories through Makefile) remain in config.log. To avoid invalid invocation of preprocessor for build environment, we need to set proper CPPFLAGS_FOR_BUILD (may be empty) and pass it to subdirectories that need it. This is what this commit does. ChangeLog: * configure.ac: Pass CPPFLAGS_FOR_BUILD to subdirectories. * configure: Regenerate.
2022-08-10Disable year 2038 support on 32-bit hosts by defaultLuis Machado1-0/+18
With a recent import of gnulib, code has been pulled that tests and enables 64-bit time_t by default on 32-bit hosts that support it. Although gdb can use the gnulib support, bfd doesn't use gnulib and currently doesn't do these checks. As a consequence, if we have a 32-bit host that supports 64-bit time_t, we'll have a mismatch between gdb's notion of time_t and bfd's notion of time_t. This will lead to mismatches in the struct stat size, leading to memory corruption and crashes. This patch disables the year 2038 check for now, which makes things work reliably again. I'd consider this a temporary fix until we have proper bfd checks for the year 2038, if it makes sense. 64-bit hosts seems to be more common these days, so I'm not sure how important it is to have this support enabled and how soon we want to enable it. Thoughts?
2022-06-27[gdb/build] Fix build breaker with --enable-sharedTom de Vries1-2/+6
When building gdb with --enable-shared, I run into: ... ld: build/zlib/libz.a(libz_a-inffast.o): relocation R_X86_64_32S against \ `.rodata' can not be used when making a shared object; recompile with -fPIC ld: build/zlib/libz.a(libz_a-inflate.o): warning: relocation against \ `inflateResetKeep' in read-only section `.text' collect2: error: ld returned 1 exit status make[3]: *** [libbfd.la] Error 1 ... This is a regression since commit a08bdb159bb ("[gdb/build] Fix gdbserver build with -fsanitize=thread"). The problem is that a single case statement in configure is shared to handle special requirements for both the host libiberty and host zlib, which has the effect that only one is handled. Fix this by handling libiberty and zlib each in its own case statement. Build on x86_64-linux, with and without --enable-shared.

[ Copied from gcc commit 153689603fd ("[gdb/build] Fix gdbserver build with -fsanitize=thread"). ] When building gdbserver with -fsanitize=thread (added to CFLAGS/CXXFLAGS) we run into: ... ld: ../libiberty/libiberty.a(safe-ctype.o): warning: relocation against \ `__tsan_init' in read-only section `.text' ld: ../libiberty/libiberty.a(safe-ctype.o): relocation R_X86_64_PC32 \ against symbol `__tsan_init' can not be used when making a shared object; \ recompile with -fPIC ld: final link failed: bad value collect2: error: ld returned 1 exit status make[1]: *** [libinproctrace.so] Error 1 ... which looks similar to what is described in commit 78e49486944 ("[gdb/build] Fix gdbserver build with -fsanitize=address"). The gdbserver component builds a shared library libinproctrace.so, which uses libiberty and therefore requires the pic variant. The gdbserver Makefile is setup to use this variant, if available, but it's not there. Fix this by listing gdbserver in the toplevel configure alongside libcc1, as a component that needs the libiberty pic variant, setting: ... extra_host_libiberty_configure_flags=--enable-shared ... Tested on x86_64-linux. ChangeLog: 2022-06-27 Tom de Vries <tdevries@suse.de> * configure.ac: Build libiberty pic variant for gdbserver. * configure: Regenerate.
2022-04-08Pass PKG_CONFIG_PATH down from top-level MakefileSimon Marchi1-0/+1
[Sending to binutils, gdb-patches and gcc-patches, since it touches the top-level Makefile/configure] I have my debuginfod library installed in a non-standard location (/opt/debuginfod), which requires me to set PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config. If I just set it during configure: $ PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config ./configure --with-debuginfod $ make or $ ./configure --with-debuginfod PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config $ make Then PKG_CONFIG_PATH is only present (and ignored) during the top-level configure. When running make (which runs gdb's and binutils' configure), PKG_CONFIG_PATH is not set, which results in their configure script not finding the library: checking for libdebuginfod >= 0.179... no configure: error: "--with-debuginfod was given, but libdebuginfod is missing or unusable." Change the top-level configure/Makefile system to capture the value passed when configuring the top-level and pass it down to subdirectories (similar to CFLAGS, LDFLAGS, etc). I don't know much about the top-level build system, so I really don't know if I did this correctly. The changes are: - Use AC_SUBST(PKG_CONFIG_PATH) in configure.ac, so that @PKG_CONFIG_PATH@ gets replaced with the actual PKG_CONFIG_PATH value in config files (i.e. Makefile) - Add a PKG_CONFIG_PATH Makefile variable in Makefile.tpl, initialized to @PKG_CONFIG_PATH@ - Add PKG_CONFIG_PATH to HOST_EXPORTS in Makefile.tpl, which are the variables set when running the sub-configures I initially added PKG_CONFIG_PATH to flags_to_pass, in Makefile.def, but I don't think it's needed. AFAIU, this defines the flags to pass down when calling "make" in subdirectories. We only need PKG_CONFIG_PATH to be passed down during configure. After that, it's captured in gdb/config.status, so even if a "make" causes a re-configure later (because gdb/configure has changed, for example), the PKG_CONFIG_PATH value will be remembered. ChangeLog: * configure.ac: Add AC_SUBST(PKG_CONFIG_PATH). * configure: Re-generate. * Makefile.tpl (HOST_EXPORTS): Pass PKG_CONFIG_PATH. (PKG_CONFIG_PATH): New. * Makefile.in: Re-generate.

2021-09-28top-level configure: setup target_configdirs based on repositoryAndrew Burgess1-0/+10
The top-level configure script is shared between the gcc repository and the binutils-gdb repository. The target_configdirs variable in the configure.ac script, defines sub-directories that contain components that should be built for the target using the target tools. Some components, e.g. zlib, are built as both host and target libraries. This causes problems for binutils-gdb. If we run 'make all' in the binutils-gdb repository we end up trying to build a target version of the zlib library, which requires the target compiler be available. Often the target compiler isn't immediately available, and so the build fails. The problem with zlib impacted a previous attempt to synchronise the top-level configure scripts from gcc to binutils-gdb, see this thread: https://sourceware.org/pipermail/binutils/2019-May/107094.html And I'm in the process of importing libbacktrace in to binutils-gdb, which is also a host and target library, and triggers the same issues. I believe that for binutils-gdb, at least at the moment, there are no target libraries that we need to build. In the configure script we build three lists of things we want to build, $configdirs, $build_configdirs, and $target_configdirs, we also build two lists of things we don't want to build, $skipdirs and $noconfigdirs. We then remove anything that is in the lists of things not to build, from the list of things that should be built. My proposal is to add everything in target_configdirs into skipdirs, if the source tree doesn't contain a gcc/ sub-directory. The result is that for binutils-gdb no target tools or libraries will be built, while for the gcc repository, nothing should change. If a user builds a unified source tree, then the target tools and libraries should still be built as the gcc/ directory will be present. I've tested a build of gcc on x86-64, and the same set of target libraries still seem to get built. On binutils-gdb this change resolves the issues with 'make all'. ChangeLog: * configure: Regenerate. * configure.ac (skipdirs): Add the contents of target_configdirs if we are not building gcc.

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.

2020-02-07Move gdbserver to top levelTom Tromey1-2/+18
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.

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.

2019-08-19Add --with-static-standard-libraries to the top levelTom Tromey1-1/+15
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.

2019-06-14Move gnulib to top levelTom Tromey1-1/+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.
