signames1.awk   [plain text]

# 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.
