- # 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.
