2023-08-07PR29961, plugin-api.h: "Could not detect architecture endianess"Alan Modra1-22/+23
Found when attempting to build binutils on sparc sunos-5.8 where sys/byteorder.h defines _BIG_ENDIAN but not any of the BYTE_ORDER variants. This patch adds the extra tests to cope with the old machine, and tidies the header a little. include/ChangeLog: * plugin-api.h: When handling non-gcc or gcc < 4.6.0 include necessary header files before testing macros. Make more use of #elif. Test _LITTLE_ENDIAN and _BIG_ENDIAN in final tests.
2023-05-11Implement LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [PR109128]Joseph Myers1-0/+16
This is one part of the fix for PR109128, along with a corresponding binutils's linker change. Without this patch, what happens in the linker, when an unused object in a .a file has offload data, is that elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p, which ends up calling the plugin's claim_file_handler, which then records the object as one with offload data. That is, the linker never decides to use the object in the first place, but use of this _p interface (called as part of trying to decide whether to use the object) results in the plugin deciding to use its offload data (and a consequent mismatch in the offload data present at runtime). The new hook allows the linker plugin to distinguish calls to claim_file_handler that know the object is being used by the linker (from ldmain.c:add_archive_element), from calls that don't know it's being used by the linker (from elf_link_is_defined_archive_symbol); in the latter case, the plugin should avoid recording the object as one with offload data.

2017-11-10Add plugin API for processing plugin-added input files.Stephen Crane1-1/+17
Gold plugins may wish to further process an input file added by a plugin. For example, the plugin may need to assign a unique segment for sections in a plugin-generated input file. This patch adds a plugin callback that the linker will call when reading symbols from a new input file added after the all_symbols_read event (i.e. an input file added by a plugin). 2017-11-10 Stephen Crane <sjc@immunant.com> * plugin-api.h: Add plugin API for processing plugin-added input files.
