--- Comment #9 from Sourceware Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Rainer Orth <[email protected]>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=7d0f24dfbdafc52d54316d3bfd688cbf8f8ae037 commit 7d0f24dfbdafc52d54316d3bfd688cbf8f8ae037 Author: Rainer Orth <[email protected]> Date: Thu Dec 11 14:43:16 2025 +0100 Cleanup bfd target vectors and ld emulations on Solaris This patch is a major cleanup of the Solaris configurations of both bfd and ld. The Solaris cases in both bfd/config.bfd and ld/configure.tgt have seen a major cleanup, making the support for various Solaris versions explicit, correcting several inconsistencies, and making it easier to remove support for some versions in the future. * All 32-bit-only configurations (Solaris < 7 on SPARC, Solaris < 10 on x86) only include the 32-bit target vectors and linker emulations. * For 32-bit-default targets on 64-bit systems (Solaris >= 7 on SPARC, Solaris >= 10 on x86), the 32-bit target vectors and linker emulations are the default while supporting the 64-bit ones. * For 64-bit-default targets on 64-bit systems, it's the other way round. They default to 64-bit target vectors etc. while also supporting the 32-bit ones. * Added a warning to all Solaris cases in config.bfd not to include the non-*_sol2 vectors to avoid the ambiguity reported in PR binutils/27666. * On x86, the iamcu target vectors and linker emulations have been removed: Solaris never supported the Intel MCU. * On x86, the PE and PEI target vectors have been removed: they were only supported in binutils proper. Their only use would be on EFI files e.g. in GRUB, which doesn't justify their inclusion. * With iamcu support gone, a few gas tests had to be disabled as on VxWorks. * The 32-bit Solaris/x86 ld configuration currently includes the elf_i386_ldso emulation, which was never a emulation in its own right but just an implementation detail of the elf_i386_sol2 emulation. Instead, the settings that are not already provided by sourced .sh files are moved into elf_i386_sol2.sh. Many settings became superfluous by just sourcing elf_i386.sh as is already done in elf_x86_64_sol2.sh, massively simplifying the emulation. * Solaris-specific settings in generic emulparams scripts have been moved to the *_sol2.sh files. * NATIVE_LIB_DIRS in ld/configure.tgt now uses the default setting: /usr/ccs/lib contains just a bunch of symlinks into /usr/lib at least since Solaris 8. * ld/emulparams/solaris2.sh now sets ELF_INTERPRETER_NAME to /usr/lib/amd64/ld.so.1, matching both the native linker and elf_i386_sol2.sh. * The SEARCH_DIR statements in linker scripts on 64-bit targets contained both the native (64-bit) and non-default (32-bit) directies. The latter are completely pointless and are omitted using a new LIBPATH_SKIP_NONNATIVE setting. Tested on {amd64,i386}-pc-solaris2.11 and {sparcv9,sparc}-sun-solaris2.11, and {x86_64,i686}-pc-linux-gnu as well as with gcc trunk bootstraps on the Solaris targets. On those, I've compared the gas/ld and gas/gld 2.45.50 testresults with 2.45 ones. 2025-09-09 Rainer Orth <[email protected]> bfd: * config.bfd <i[3-7]86-*-solaris2*>: Split into ... <i[3-7]86-*-solaris2.1[01]*> ... this.
