You can only change memory which the core isn't using itself at the moment. When changing memory on which the core has put software breakpoint instructions the set-aside memory of the Instruction should be changed (so that if the breakpoint is removed or stepped the new code is used). This is a little tricky to change. When a Breakpoint is found installed the underlying Instruction class should be altered (but Instruction is currently a immutable class). Care should be taken if the Breakpoint is currently stepped, or if the memory is changed asynchronous from the event thread (which means it could intersect with a breakpoint being placed right at the same time). -- Summary: LogicMemory poke of code which has a breakpoint Product: frysk Version: unspecified Status: NEW Severity: normal Priority: P2 Component: general AssignedTo: frysk-bugzilla at sourceware dot org ReportedBy: mark at klomp dot org http://sourceware.org/bugzilla/show_bug.cgi?id=5202 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
