  34 # Usage: m4-ccas --m4=M4 CC ... file.asm ...
  35 #
  36 # Process file.asm with the given M4 plus any -D arguments, then
  37 # assemble with the given CC plus all arguments.
  38 #
  39 # The M4 command must be in a single --m4= argument, and will be split
  40 # on whitespace.  When CC is invoked file.asm is replaced with a
  41 # temporary .s file which is the M4 output.
  42 #
  43 # To allow parallel builds, the temp file name is based on the .asm
  44 # file name, which will be the output object filename for all uses we
  45 # put this script to.
