Hi, I experience the following problem: Setting the trap flag (TF) of the EFLAGS register correctly calls the debug exception DE. However, the DR6 register does not have the single step (BS) flag set.
This patch fixes things for me, and I think it deserves some more attention given that it had no replies at that time and it's not in the latest release. http://lists.gnu.org/archive/html/qemu-devel/2007-03/msg00126.html Vegard
