# Usage: cpp-cc --cpp=CPP CC ... file.S ...
#
# Process file.S with the given CPP command plus any -D options in the
# rest of the arguments, then assemble with the given CC plus all
# arguments.
#
# The CPP command must be in a single --cpp= argument, and will be
# split on whitespace. It should include -I options required.
#
# When CC is invoked, file.S is replaced with a temporary .s file
# which is the CPP output.
#
# Any lines starting with "#" are removed from the CPP output, usually
# these will be #line and #file markers from CPP, but they might also
# be comments from the .S.
#
# To allow parallel builds, the temp file name is based on the .S file
# name, which will be the output object filename for all uses we put
# this script to.
