------- Comment #6 from pinskia at gcc dot gnu dot org 2005-10-24 18:05 -------
Marking this as a 4.1 regression and moving to the target milestone as 4.1 as
it could most likely show up in C++ code too. For some analysis see PR 15023.

Incidentally, this bug started getting tickled (more, at least) on darwin due
to the fix for 15813. I'm not aware of any problems before that. However, the
15813 fix is correct and necessary.

CCing Zdenek as he introduced this regression by enabling rename registers for
unrolling loops.

This is probably a dup of Bug 22509, which has a patch.
Can someone check if this bug is fixed by the patch from Bug 22509?

I doubt this is related at all to PR 22509 because this has to do with checking
of register number to another register (after reload) without updating the eh
info.
