No. I'm using the trunk of the tree, updated yesterday, and your
patch seems to be there:
Web Feb 13 23:41:15 CET 2002 Jan Hubicka <firstname.lastname@example.org>
* regmove.c (kill_value): Handle subregs.
I'll have a look at kill_value and its surroundings to see if I can
find the problem.
By the way, kill_value is in regrename.c, not regmove.c.
