* Changed InternalClass to store Identifier* instead of String*Simon Hausmann2014-11-211-5/+2
| | | | | | | | | All members are identifiers anyway, so this gets rid of a ### and also simplifies some of the call sites by removing the need for a scoped string. Change-Id: Ic6b550cdb97afa5a4b0fa7e9b13e7768ed3f6bd8 Reviewed-by: Lars Knoll <[email protected]>
* Fix run-time string handling with regards to the new heapSimon Hausmann2014-11-211-4/+5
| | | | | | | | | | | | | | | | | Changed runtimeStrings to be an array of Heap::String pointers instead of indirect String pointers. Later that member along with other GC related members will go into a managed subclass. Meanwhile the generated code no more loads String pointers directly but just passes the index into the run-time strings to the run-time functions, which in turn will load the heap string into a scoped string. Also replaced the template<T> Value::operator=(T *m) with a non-template overload that takes a Managed *, in order to help the compiler choose the non-template operator=(Heap::Base *) overload. This allows removing a bunch of Value::fromHeapObject calls. Change-Id: I20415c0549d33cca6813441a2495976b66d4c00e Reviewed-by: Lars Knoll <[email protected]>
* Ported ExecutionEngine::newString and newIdentifier to Heap::StringSimon Hausmann2014-11-121-1/+1
| | | | | | | | | | Avoid the use of Returned<String> for newString and changed the identifier table to use Heap::String. This required moving some code back into Heap::String, but that's code that doesn't call back into the GC, so allocations and therefore future object moves aren't possible.

* V4 debugging: fix step-over and step-out.Erik Verbruggen2013-11-141-11/+14
| | | | | | | | | | | | | | | | - 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).
