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