To force a trap into the kernel. That's not the same
as HW support since using break requires modifying the code stream
(remembering which instruction belonged there), flushing data-cache,
flush ins-cache, an dtrying to continue. The break's are fully
under SW control.

That's because HP has (had?) a team of folks working on the
"open source toolkit". parisc-linux hasn't been so lucky.
Alan Modra, Richard Hirst, Randolph Chung and a few others get gdb
working from time to time. But there is no dedicated maintainer
and that's what is needed.
