Joseph, if I understand correctly, this is now an hppa64-hp-hpux* problem only,
and is not a regression. If that's correct, would you please (a) fill in the
target field, (b) update the summary line to

But it is not as the x86 one was about combine generating bad subregs but
combine in this case is not
generating bad subregs

Are you sure the bug is fixed? The testcase is failing for me with today's
mainline compiler on i686-pc-linux-gnu, ia64-hp-hpux11.23 and
hppa64-hp-hpux11.{11,23}.
Failure on i686-pc-linux-gnu is that quoted
