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.
