objdump: Better objdump section headers in wide mode
When displaying the section headers table using objdump (-h), the column
containing the section header name is currently fixed at 13 characters.
A section name that is longer than 13 characters will overflow the
column causing the table to become miss-aligned.
In this commit I change the behaviour so that _in wide mode_ (-w -h) the
section name column is dynamically resized to fit the longest section
name we plan to display. In wide mode the column still retains a
minimum width of 13 characters.
In non-wide more the behaviour is completely unchanged.
While I was changing the dump_headers function I have unified the two
printf lines that handled the different address widths into a single
printf, the address width is now passed into printf using the '*' field
width format character.
binutils/ChangeLog:
* objdump.c (dump_section_header): Extract max section name length
from data parameter, use this when formatting output.
(find_longest_section_name): New function.
(dump_headers): Calculate longest section name when in wide mode,
reformat to unify printing of header line.
ld/ChangeLog:
* testsuite/ld-elf/eh-frame-hdr.d: Update expected results.
