From 05068c0dfb5b23dde42ad0112123bdc8408a1f44 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 12 Sep 2014 14:06:48 +0100 Subject: exec.c: Relax restrictions on watchpoint length and alignment The current implementation of watchpoints requires that they have a power of 2 length which is not greater than TARGET_PAGE_SIZE and that their address is a multiple of their length. Watchpoints on ARM don't fit these restrictions, so change the implementation so they can be relaxed.
