22 | How does this releate to the rest of GAS ? | |
23 | ||
24 | Well, all the other files in gas are more or less a black box. It | |
25 | takes care of opening files, parsing command lines, stripping blanks | |
26 | etc etc. This module gets a chance to register what it wants to do by | |
27 | saying that it is interested in various pseduo ops. The other big | |
28 | change is write_object_file. This runs through all the data | |
29 | structures that gas builds, and outputs the file in the format of our | |
30 | choice. | |
