            Bug ID: 29627
           Summary: The help document of gprof misses some options
           Product: binutils
           Version: 2.39
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gprof
          Assignee: unassigned at sourceware dot org
          Reporter: mengda2020 at iscas dot ac.cn
  Target Milestone: ---

The "-h" option of gprof misses the option "B".

1） For the option "B", the following code appears during option parsing and
modifies output_style and user_specified in gprof/gprof.c:226-228 for version
2.39.

          output_style |= STYLE_CALL_GRAPH;
          user_specified |= STYLE_CALL_GRAPH;
          break;


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

It may prevent users from using the relevant function.
