Hi Guys,
I have checked in the following patch to readelf to allow it to
decode the new values that were recenetly added to
include/elf/common.h.
Cheers
Nick
1999-12-28 Nick Clifton <nickc@cygnus.com>
* readelf.c: Update with new constants added by Oct 4, 1999
ELF ABI draft.
(guess_is_rela): Add new machine codes, but leave
rel type undetermined.
(get_machine_name): Add new machine codes.
(get_section_type_name): Add new section types.
(get_elf_section_flags): New funciton: Decode section flags.
(process_section_headers): Call get_elf_section_flags() in
order to decode flags in section header.
(get_dynamic_flags): New function: Decode dynamic section
flags.
(process_dynamic_section): Display flags (if present).
(get_symbol_type): Add STT_COMMON.
(get_symbol_visibility): New function: Decode a symbol's
visibility.
(process_symbol_table): Call get_symbol_visibility().
(get_note_type): Add NT_PRXFPREGS.
