But what's BREAK instruction for? 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. > Besides gdb works for me on HPUX 11.00 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. grant
