attached declarations described in the info files, the "Using and

Porting GCC" manual (uapgcc), in the same order as found in the "Target

really, but needs an update anyway.

There is no generic copy-of-uapgcc comment, you'll have to see uapgcc
|
|
for that. If applicable, there is a CRIS-specific comment. The order
|
|
of macro definitions follow the order in the manual. Every section in
|
|
the manual (node in the info pages) has an introductory `Node:
|
|
<subchapter>' comment. If no macros are defined for a section, only
|
|
the section-comment is present. */
