Initial value:

=
{
  { "arch-disassemble", 2, 0, 1, as_a_scm_t_subr (gdbscm_arch_disassemble),
    "\
Return list of disassembled instructions in memory.\n\
\n\
  Arguments: <gdb:arch> start-address\n\
      [#:port port] [#:offset address]\n\
      [#:size <integer>] [#:count <integer>]\n\
    port: If non-#f, it is an input port to read bytes from.\n\
    offset: Specifies the address offset of the first byte in the port.\n\
      This is useful if the input is from something other than memory\n\
      (e.g., a bytevector) and you want the result to be as if the bytes\n\
      came from that address.  The value to pass for start-address is\n\
      then also the desired disassembly address, not the offset in, e.g.,\n\
      the bytevector.\n\
    size: Limit the number of bytes read to this amount.\n\
    count: Limit the number of instructions to this amount.\n\
\n\
  Returns:\n\
    Each instruction in the result is an alist:\n\
      (('address . address) ('asm . disassembly) ('length . length))." },
