23 /* Solaris x86 2.6 and 2.7 targets have a kernel bug when stepping
24 over an instruction that causes a page fault without triggering
25 a hardware watchpoint. The kernel properly notices that it shouldn't
26 stop, because the hardware watchpoint is not triggered, but it forgets
27 the step request and continues the program normally.
28 Work around the problem by removing hardware watchpoints if a step is
29 requested, GDB will check for a hardware watchpoint trigger after the
