You may want to change mach.c in this directory.
|
||
|
|
||
|
Archives MUST have a table of contents. Arch in subdirectory arch
|
||
|
automatically makes one when you change an archive.
|
||
|
|
||
|
Several changes in the assembler were needed to have it generate the
|
||
|

|
||
|
A contextual diff follows. You can apply them as follows:
|
||
|
patch -d /usr/em/philips/mach/68000/as < READ_ME
