The process of using gdcc-acc is under most circumstances identical to that of using the regular acc compiler. As a result, it can safely be used as a direct substitute for acc in utilities such as Slade.

Usage of gdcc-acc is as simple as the following:

gdcc-acc <input file>.acs <output file>.bin

Do note that there are some specific incompatibilities with ACC which should be accounted for in code using gdcc-acc.

In addition to the standard acc syntax, gdcc-acc has a plethora of additional command-line parameters that may be used, which can be listed by either running gdcc-acc without arguments, or passing the -h (--help) argument.

Most of these are useful only to gdcc-cc users, since these abilities are shared with that program. However, under very specific circumstances, these can be useful.

As of version 0.11.0, the default output of gdcc-acc is:

gdcc-acc v0.11.0
usage: gdcc-acc [option]... [source]...

Compiles ACS source into IR data. Output defaults to last loose argument.

  -h, --help       Prints usage and exits.
