(_bfd_XXi_swap_debugdir_in, _bfd_XXi_swap_debugdir_out) (_bfd_XXi_slurp_codeview_record, _bfd_XXi_write_codeview_record): Add functions for reading and writing debugdir and codeview records. * libpei.h (_bfd_XXi_swap_debugdir_in, _bfd_XXi_swap_debugdir_out) (_bfd_XXi_write_codeview_record): Add prototypes and macros. * libcoff-in.h (pe_tdata): Add build-id data. * libcoff.h: Regenerate. * coffcode.h (coff_write_object_contents): Run build_id after_write_object_contents hook. * pe.h (external_IMAGE_DEBUG_DIRECTORY, _CV_INFO_PDB70) (_CV_INFO_PDB20): Add structures and constants for debug directory and codeview records. * internal.h (internal_IMAGE_DEBUG_DIRECTORY, CODEVIEW_INFO): Add structures and constants for internal representation of debug directory and codeview records. * emultempl/elf32.em (id_note_section_size, read_hex, write_build_id): Move code for parsing build-id option and calculating the build-id to... * ldbuildid.c: New file. * ldbuildid.h: New file. * Makefile.am (CFILES, HFILES, OFILES, ld_new_SOURCES): Add new files. * Makefile.in: Regenerate. * ld.texinfo: Update --build-id description to mention COFF support. * NEWS: Mention support for COFF build ids. * emultempl/pe.em (gld${EMULATION_NAME}_handle_option): (pecoff_checksum_contents, write_build_id, setup_build_id) (gld_${EMULATION_NAME}_after_open): Handle and implement build-id option. * emultempl/pep.em: Likewise. --- ld/ldmain.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'ld/ldmain.c') diff --git a/ld/ldmain.c b/ld/ldmain.c index 14253a6..b132dae 100644 --- a/ld/ldmain.c +++ b/ld/ldmain.c @@ -378,6 +378,13 @@ main (int argc, char **argv) lang_final (); + /* If the only command line argument has been -v or --version or --verbose + then ignore any input files provided by linker scripts and exit now. + We do not want to create an output file when the linker is just invoked + to provide version information. */ + if (argc == 2 && version_printed) + xexit (0); + if (!lang_has_input_file) { if (version_printed || command_line.print_output_format) -- cgit v1.1
