Yeah, I'd actually prefer it in the code itself so that we can find it easier.
This file is as good as any.
Something like this:
/*
* Summarized explanation that "cc" clobbers don't have a meaning
*
*/
and leave the "cc" clobber there but commented out:
/* "cc" ... */
so that we can grep for it easier later.
Thanks!
