------- Comment #1 from hp at gcc dot gnu dot org 2010-04-26 02:36 -------
The regrename change renamed registers so the destination overlapped a clobber
in the div (or mod) insns. That in turn can be blamed on missing earlyclobbers
for those alternatives in the patterns, thus changing component to "target".
Bernd, sorry for the noise. Feel free to re-add yourself as CC. :-)
