            Bug ID: 29628
           Summary: The help document of size misses an option.
           Product: binutils
           Version: 2.39
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: mengda2020 at iscas dot ac.cn
  Target Milestone: ---

The "-h" option of readelf misses the option "f". 

1） For the option "f", the following code appears during option parsing in
binutils/size.c:231-240 for version 2.39.

      case 'f': /* FIXME : For sysv68, `-f' means `full format', i.e.
                   `[fname:] M(.text) + N(.data) + O(.bss) + P(.comment) = Q'
                   where `fname: ' appears only if there are >= 2 input files,
                   and M, N, O, P, Q are expressed in decimal by default,
                   hexa or octal if requested by `-x' or `-o'.
                   Just to make things interesting, Solaris also accepts -f,
                   which prints out the size of each allocatable section, the
                   name of the section, and the total of the section sizes.  */
                /* For the moment, accept `-f' silently, and ignore it.  */
        break;

Although it has no actual function, it is still possible forget to modify the
help document after adding the function in a subsequent update.

But they do not appear in the document provided by "-h".

It may prevent users from using the relevant function.
