* Allow detaching V4 debuggers in agent destructorUlf Hermann2014-03-111-0/+3
| | | | | | | | We don't know in which order the QML engines and the debug service are deleted on shutdown. Change-Id: I9d23b3c88eee125a93c5b0f8ea85466013233737 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

| | | | | | | | | | This unifies the way we handle line numbers in the JIT and Interpreter. Remove the now unused lineNumberMapping code and data. Change-Id: I1d60b1fbb77e70b531fa73d93410683e84dd1e3c Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Simplify our breakpoint handlingLars Knoll2014-03-071-201/+32
| | | | | | | | | | | | | | | | | Only store a Hash of break points in the debugger, instead of the involved logic that currently adds and removes break points. Add the current line number to the Debug statements in the interpreter, and pass them on to the debugger for checking whether we should really break. This adds a slight additional overhead to running inside the debugger, but greatly simplifies the logic and doesn't require modifying the bytecode anymore. This in turn opens up the possibility to run the debugger on JIT generated code later on. Change-Id: If2a3ae8f8d08b69a3a704cbbe0a84000f917a32e Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Make the Ref classes not template basedLars Knoll2014-02-071-1/+1
| | | | | | | | | | Move to a class hierarchy that mirrors the main classes. This will allow moving functionality over into the Ref classes, as the current Managed classes become mainly something that holds the data. This is required to make objects movable by the GC.

* Add a special Debug instruction to the interpreter and use itLars Knoll2014-02-051-4/+4
| | | | | | | | | | | | | | | This avoid having to check for the debugger at every instruction we execute. Instead we only add debug instructions at the beginning of every line and every basic block when we have a debugger. This still allows interrupting the JS execution at any time (as we can't loop inside a basic block), and single stepping through lines. But it has no overhead when the debugger is not running and a lot less when it is running.

* V4 debugging: fix step-over and step-out.Erik Verbruggen2013-11-141-19/+30
| | | | | | | | | | | | | | | | - step-out: only stop if we’re leaving the context for the function we previously stopped at, so intermediate calls between the current position and the end do not stop the engine - step-over: set breakpoints on all lines in current function and continue to run. When hitting a breakpoint, see if we are in the same context, because recursive calls might happen. Breakpoints on all lines are needed, because the (pure) next line might be jumped over (like when doing step-over a single-line then clause, where the next line might be in the else clause).
