Now, I get the end address of a function with command "disassemble
function_name".
Does GDB have an command to output the end address of a function?
Thanks,
Hui

i'm not aware of anything, there is the following which could be made
into a user defined command or something.
py gdb.execute("p/x %s" %
gdb.block_for_pc(gdb.decode_line("*main")[1][0].pc).end)
seems to differ slightly from 'disassemble' I suppose by the length of
the last instruction

The end address of a function is not well defined (and neither is the
beginning address of a function). It is perfectly valid for two
functions to be interleaved in some way, or having their code spread out
in non-contiguous regions.
