# This is an awk script which finds out what the possibilities for
|
|
# the signal names are, and dumps them out so that cpp can turn them
|
|
# into numbers. Since we don't need to decide here what the
|
|
# real signals are, we can afford to be generous about definitions,
|
|
# in case the definitions are in terms of other definitions.
|
|
# However, we need to avoid definitions with parentheses, which will
|
|
# mess up the syntax.
