From 76cfced5addbd827652688a13f9cfa02afce51a5 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 3 Jul 2017 21:59:45 +0930 Subject: Support %Lx, %Lu, %Ld in _bfd_error_handler format One way to print 64-bit bfd_vma or bfd_size_type values on 32-bit hosts is to cast the value to long long and use the 'll' modifier in printf format strings. However, that's awkward because we also support the Microsoft C library printf that uses 'I64' as a modifier instead, and having variants of translated strings would not endear us to the translation project. So, rewrite the 'll' modifier in _doprint for Microsoft. Even with that capability it's not so nice for 32-bit code to need casts to long long, so this patch makes 'L' a modifier for bfd_vma rather than an alias for 'll'. I've then used the new 'L' modifier to fix selected format strings. * bfd.c (_doprnt): Rewrite "ll" and "L" modifiers to "I64" for __MSVCRT__. Support "L" modifier for bfd_vma. Formatting. * elf.c (setup_group): Use "Lx" to print sh_size. (_bfd_elf_setup_sections): Remove unnecessary cast and print unknown section type in hex. (copy_special_section_fields): Style fix. (bfd_section_from_shdr): Correct format for sh_link. Use a common error message for all the variants of unrecognized section types. (assign_file_positions_for_load_sections): Use "Lx" for lma adjust error message. (assign_file_positions_for_non_load_sections): Formatting. (rewrite_elf_program_header): Formatting. Use "Lx" for bfd_vma values in error messages. * elfcode.h (elf_slurp_reloc_table_from_section): Cast ELF_R_SYM value to type expected by format. * elflink.c (elf_link_read_relocs_from_section): Use "Lx" in error messages. (elf_link_add_object_symbols): Use "Lu" for symbol sizes. (elf_link_input_bfd): Use "Lx" for r_info. (bfd_elf_gc_record_vtinherit): Use "Lx" for offset. --- bfd/ChangeLog | 24 ++++++++++++++++++++++++ bfd/bfd.c | 24 +++++++++++++++++++++--- bfd/elf.c | 54 ++++++++++++++++++++++++++---------------------------- bfd/elfcode.h | 2 +- bfd/elflink.c | 24 ++++++++++-------------- 5 files changed, 82 insertions(+), 46 deletions(-) (limited to 'bfd') diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 74cb0c9..523610f 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,5 +1,29 @@ 2017-07-03 Alan Modra + * bfd.c (_doprnt): Rewrite "ll" and "L" modifiers to "I64" for + __MSVCRT__.
