The default watchpoint handler is NULL. That means any port that sets the STATE_WATCHPOINTS->pc field will crash if you try to use the --watch options but don't configure the interrupt handler. In the past, you had to setup STATE_WATCHPOINTS->pc if you wanted to support PC profiling, and while that was fixed a while ago, we have a lot of ports who still configure it. We already add a default set of interrupts (just "int") if the port doesn't define any. Let's also add a default handler that raises a SIGTRAP. When connected to gdb, this is a breakpoint which is what people would expect. When running standalone, it'll abort the sim, but it's unclear whether there's anything better to do there. This really is just to make the watchpoint module more usable out of the box for most ports with very little setup, at least inside of gdb. |
