# this is a collection of support procs for the target data
28
# structures. We use a named array, since Tcl has no real data
29
# structures. Here's the special index words for the array:
30
# Required fields are:
31
# name - the name of the target. (mostly for error messages) This
32
# should also be the string used for this target's array.
33
# It should also be the same as the linker script so we
34
# can find them dynamically.
35
# Optional fields are:
36
# ldflags - the flags required to produce a fully linked executable.
37
# config - the target canonical for this target. This is a regexp
38
# as passed to istarget or isnative.
39
# cflags - the flags required to produce an object file from a
41
# connect - the connectmode for this target. This is for both IP and
43
# hostname - the hostname of the target. This is for TCP/IP based
44
# connections, and is also used for versions of tip that
46
# serial - the serial port. This is typically /dev/tty? or com?:.
47
# baud - the baud rate for a serial port connection.
48
# netport - the IP port.
49
# x10 - parameters for the x10 controller (used to reboot)
50
# fileid - the fileid or spawn id of of the connection.
51
# prompt - a regexp for matching the prompt.
52
# ioport - the port for I/O on dual port systems.
54
# there are three main arrays, indexed in with "target", "build", and "host".
