------- Comment #1 from vmakarov at redhat dot com 2008-04-02 18:34 -------
I've just fixed it on ira branch. The problem was in an assert requiring
nonzero number of references for an allocno. I permitted to have zero number
of references.
I've just realized that such situations are possible in a region but something
is wrong with this particular case. The pseudo-register 69 lives at the
start/end of each basic block there is no such pseduo-register in RTL. It is
removed in ce2. Either the live info was not updated or something wrong with
the updating itself.
Therefore I am not closing IRA and I am adding Ken to the list. I think the
problem can be reproduced on the mainline because I've merged the trunk into
the branch recently.
