Assuming that for VLIW gdb replaces the entire instruction bundle with a
breakpoint, a breakpoint instruction can only ever generate a sigtrap
(et.al.) (if executed) or sigsegv (if not accessible) so provided there
is a breakpoint at the PC I don't think there is any possability of
confusion (but again ignore decr pc after break :-).
So does this mean you're convinced that we can add SIGSEGV to the list
currently consisting of SIGILL and SIGEMT unconditionally? I haven't
seen any ill effects on IA-32 and AMD64 (which are decr pc after
break). I'll happilly check in the origional patch in mainline too.
