Setting up 176 microsecond delay to stall execution after a watchpoint has been set up. 242 If we deliberately stall a memory access, while we have a watchpoint for its 243 address set up, and then observe the watchpoint to fire, two accesses to the 258 2. Periodically, if no matching watchpoint exists, set up a watchpoint and 265 marked accesses, but only to check if a watchpoint exists; i.e. KCSAN never 266 sets up a watchpoint on marked accesses. By never setting up watchpoints for 326 longs to encode watchpoint information, which is negligible. [all …]
