In addition to specifying commands in the argument list, you may also specify a “response file”. A response file’s filename begins with an ‘@’ (for example, @file), and the contents of the response file are commands to be inserted into the argument list. The response file supports standard UNIX-style comments. For example, the response file @file, contains the following:
# Response file @file -o out.elf # change output file name to 'out.elf' -g # generate debugging symbols
The above response file can used in a command such as:
mwcc56800e @file main.c
It would be the same as using the following command:
mwcc56800e -o out.elf -g main.c
