Dear Sergey

Thank you very much for the reply and I apologize bothering you by my misunderstood.
I confirmed --main option works as documented.
Thank you for teaching me that.

Hi Hiroo!

Apologies for not being able to reply earlier.

Thank you.  However, in my opinion it does work as documented: if
the user chose to ignore static symbols, they are not shown.  If the
start symbol is declared as static, wouldn't it be better to explictly
request symbols in the output (-is)?

Regarding the patch: it ignores the fact that start_name can be
NULL (if the --no-main option is given) and will cause coredump in
this case.

Best regards,
Sergey
