Rozycki <macro@redhat.com> Date: Mon Apr 28 18:53:30 2025 +0100 Fix 64-bit BFD detection causing build failures We have a discrepancy with 64-bit BFD handling across our component subdirectories leading to link failures such as: ld: ../opcodes/.libs/libopcodes.a(disassemble.o): in function `disassembler': disassemble.c:(.text+0x65): undefined reference to `print_insn_alpha' ld: disassemble.c:(.text+0x105): undefined reference to `print_insn_ia64' ld: disassemble.c:(.text+0x11d): undefined reference to `print_insn_loongarch' ld: disassemble.c:(.text+0x1a1): undefined reference to `print_insn_big_mips' [...] with some configurations having a 32-bit host and 64-bit BFD, such as: `--host=i386-linux-gnu --target=riscv64-linux-gnu --enable-targets=all'. This is ultimately due to how 64-bit BFD is enabled for bfd/ itself and other subdirectorses and has been a regression from commit 1d5269c994bf ("unify 64-bit bfd checks"). For bfd/ the BFD_64_BIT autoconf macro from config/bfd64.m4 is used combined with this logic in bfd/configure.ac: case ${host64}-${target64}-${want64} in *true*) wordsize=64 bfd64_libs='$(BFD64_LIBS)' all_backends='$(BFD64_BACKENDS) $(BFD32_BACKENDS)' [...] ;; false-false-false) wordsize=32 all_backends='$(BFD32_BACKENDS)' ;; esac where the value of ${wordsize} switches between 32-bit and 64-bit BFD via these pieces: #define BFD_ARCH_SIZE @wordsize@ and: #if BFD_ARCH_SIZE >= 64 #define BFD64 #endif in bfd/bfd-in.h, which ultimately becomes a part of "bfd.h". Then ${host64} is determined in bfd/configure.ac from the host's word size, via the host's pointer size: if test "x${ac_cv_sizeof_void_p}" = "x8"; then host64=true fi And ${target64} is determined in bfd/configure.ac from the target's word size: if test ${target_size} = 64; then target64=true fi Where multiple targets have been requested with `--enable-targets=all' the presence of any 64-bit target will set "true" here. Finally ${want64} is set according to `--enable-64-bit-bfd' user option with an arrangement involving BFD_64_BIT: BFD_64_BIT if test $enable_64_bit_bfd = yes ; then want64=true else want64=false fi which also, redundantly, checks and sets its result upon the host's word size. Lastly ${want64} is also selectively set by target fragments in bfd/config.bfd, which mostly if not completely overlaps with ${target64} setting as described above. Conversely other subdirectories only rely on BFD_64_BIT, so they fail to notice that BFD is 64-bit and do not enable their 64-bit handling where the host requested is 32-bit and 64-bit BFD has been enabled other than with `--enable-64-bit-bfd'. One consequence is opcodes/disassemble.c enables calls to its numerous own 64-bit backends by checking the BFD64 macro from "bfd.h", however does not actually enable said backends in its Makefile. Hence the link errors quoted above. Address the problem then by moving the `--enable-64-bit-bfd' option back to bfd/configure.ac and remove the call to BFD_64_BIT from there and then rewrite the macro in terms of checking for the presence of BFD64 macro in "bfd.h", which is the canonical way of determining whether BFD is 64-bit or not. Rather than running `grep' directly on ../bfd/bfd-in3.h as the opcodes/ fragment used to before the problematic commit: if grep '#define BFD_ARCH_SIZE 64' ../bfd/bfd-in3.h > /dev/null; then run the preprocessor on "bfd.h", which allows to invoke the macro from configure.ac files placed in subdirectories located at deeper levels, by relying on the preprocessor's search path. This requires however that the invokers rely on `all-bfd' rather than `configure-bfd' for their `configure' invocation stage, because "bfd.h" is made by `make all' rather than `configure' in bfd/. Do not cache the result of this check however, as reconfiguring a tree such as to flip `--enable-64-bit-bfd' on or to change a secondary target may affect BFD64 and we have no access to information about secondary targets in BFD_64_BIT. Also remove the ENABLE_BFD_64_BIT automake conditional, as it's not used anywhere. Last but not least remove the hack from gdb/configure.ac to fail builds for `mips*-*-*' hosts where `--enable-targets=all' has been requested, but `--enable-64-bit-bfd' has not as it's no longer needed. Such builds complete successfully now, having enabled 64-bit BFD implicitly.

This patch caused problems for some users when building gdb, because it would cause 'guild' to be invoked with the wrong versin of guile. On the whole it seems simpler to just back this out. I'm checking this in to the binutils-gdb repository in the interest of fixing the build for Andrew. No one has responded to the identical patch sent to gcc-patches, but I will ping it there. commit da48217f315084097ef25226c0acab3bbd55ebd3 Author: Simon Marchi <simon.marchi@efficios.com> Date: Thu Mar 14 13:39:18 2024 -0400 gdbserver/linux: probe for libiconv in configure Make gdbserver's build system locate libiconv when building for Linux. Commit 07b3255c3bae ("Filter invalid encodings from Linux thread names") make libiconv madantory for building gdbserver on Linux. While trying to cross-compile gdb for xtensa-fsf-linux-uclibc (with a toolchain generated with crosstool-ng), I got: /home/smarchi/src/binutils-gdb/gdbserver/linux-low.cc:48:10: fatal error: iconv.h: No such file or directory 48 | #include <iconv.h> | ^~~~~~~~~ I downloaded GNU libiconv, built it for that host, and installed it in an arbitrary directory. I had to modify the gdbserver build system to locate libiconv and use it, the result is this patch. I eventually found that crosstool-ng has a config option to make uclibc provide an implementation of iconv, which is of course much easier. But given that this patch is now written, I think it would be worth merging it, it could help some people who do not have iconv built-in their libc in the future (and may not have the luxury of rebuilding their libc like I do). Using AM_ICONV in configure.ac adds these options for configure (the same we have for gdb): --with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib --without-libiconv-prefix don't search for libiconv in includedir and libdir --with-libiconv-type=TYPE type of library to search for (auto/static/shared) It sets the `LIBICONV` variable with whatever is needed to link with libiconv, and adds the necessary `-I` flag to `CPPFLAGS`. To avoid unnecessarily linking against libiconv on hosts that don't need it, set `MAYBE_LIBICONV` with the contents of `LIBICONV` only if the host is Linux, and use `MAYBE_LIBICONV` in `Makefile.in`. Since libiconv is a hard requirement for Linux hosts, error out if it is not found. The bits in acinclude.m4 are similar to what we have in gdb/acinclude.m4. Update the top-level build system to support building against an in-tree libiconv (I did not test this part though). Something tells me that the all-gdbserver dependency on all-libiconv is unnecessary, since there is already a dependency of configure-gdbserver on all-libiconv (and all-gdbserver surely depends on configure-gdbserver). I just copied what's done for GDB though. * Makefile.def: Synced from binutils-gdb. * Makefile.tpl: Likewise. * configure.ac: Likewise. * Makefile.in: Regenerated. * configure: Likewise. config/ * acx.m4: Synced from binutils-gdb. * lthostflags.m4: Likewise. libbacktrace/ * configure.ac: Synced from binutils-gdb. * configure: Regenerated. zlib/ * configure.ac: Synced from binutils-gdb. * configure: Regenerated.

2025-04-09bootstrap/119680 - fix cross-compiler build with --enable-host-sharedRichard Biener
It seems that at least when cross-compiling at least collect2 pulls in objects from libbacktrace.a which is linked via LIBDEPS. But libbacktrace for the host is only built -fPIC with --enable-host-shared but not -fPIE with --enable-host-pie so this fails. The following teaches libbacktrace about --enable-host-pie and handles it similar to libcpp. PR bootstrap/119680 libbacktrace/ * configure.ac (--enable-host-pie): Handle by setting PIC_FLAG to -fPIE. * configure: Regenerate.
2025-01-28arm: libbacktrace: Check if the compiler supports __sync atomicsRichard Earnshaw
Older versions of the Arm architecture lack support for __sync operations directly in hardware and require calls into appropriate operating-system hooks. But such hooks obviously don't exist in a freestanding environment. Consquently, it is incorrect to assume during configure that such functions will exist and we need a configure-time check to determine whether or not these routines will work. libbacktrace: * configure.ac: Always check if the compiler supports __sync operations. * configure: Regenerated.

2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe
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). ChangeLog: * configure: Regenerate. * configure.ac: Do not add default runpaths to GCC exes when we are building -static-libstdc++/-static-libgcc (the default). * libtool.m4: Add 'enable-darwin-at-runpath'.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: 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. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.
