(clone_section): Strip existing numeric suffix. Only truncate names for coff targets. (split_sections): Use unsplittable_name. binutils/ChangeLog: * objdump.c (read_section_stabs): Just read one section, return pointer to it. Add size parameter. (print_section_stabs): Add string offset parameter. Adjust. (struct stab_section_names): Add string offset member. (find_stabs_sections): Correct check for split section suffix, adjust read_section_stabs and print_section_stabs calls. (dump_stabs_section): Clear string_offset, free string table. --- binutils/ChangeLog | 10 +++++++ binutils/objdump.c | 86 +++++++++++++++++++++++------------------------------- 2 files changed, 46 insertions(+), 50 deletions(-) (limited to 'binutils') diff --git a/binutils/ChangeLog b/binutils/ChangeLog index 10c2b30..11a6dc5 100644 --- a/binutils/ChangeLog +++ b/binutils/ChangeLog @@ -1,3 +1,13 @@ +2003-10-07 Nathan Sidwell + + * objdump.c (read_section_stabs): Just read one section, return + pointer to it.
