* readelf.c (byte_get_little_endian): Comment typo fix.
(print_symbol): Constify "symbol" arg. Don't pass "symbol" to printf as the format string. (dump_relocations): Correct section sym names. (process_section_headers): Clear symtab_shndx_hdr. (read_and_display_attr_value): Don't pass indirect string to printf as the format string. (display_debug_frames): Indicate when zero terminator found. Decode DW_EH_PE_pcrel addresses.
