Hello,
this patch improves hardware watchpoint handling on s390
a bit: by default, gdb only allows hw watchpoints on regions
of size less than the word size; on s390 we have no such
restriction, so we can allow arbitrary regions.
Tested on s390-ibm-linux and s390x-ibm-linux.
(I hope this is small enough so that no specific copyright
assignment is required ...)
Bye,
Ulrich
ChangeLog:
