Hello Jeff,
If you're using something from the Cygnus port, then it would be covered
by the blanket copyright assignment Cygnus had in place with the FSF.
If there are any doubts about the origin of a hunk of GCC code I could
probably pull out the old sources to determine if it came from Cygnus's
code base or not.
Can you please tell me whether the following lines of the patches are covered
by the blanket copyright assignment?
Lines 335-533 of GCC patch (mips_r5900_lengthen_loops()):
http://pastie.org/5664783
Lines 410-565 and 581-589 of binutils patch (check_short_loop()):
http://pastie.org/5664824
The patches are from the second DVD of Sony's Linux Toolkit for the PS2.
Neither of those would be covered by the blanket assignment as to the
best of my knowledge they were not written by a Cygnus/Red Hat engineer
while working for Cygnus/Red Hat.
Clearly they're working around a chip bug, which seems to be documented
reasonably well in a comment. Given that documentation you could write
your own check for that processor bug.
