* Avoid creating array attributes if possibleLars Knoll2013-10-141-8/+3
| | | | | | | | | | | Holes in arrays should be represented by an empty value, not by creating/setting array attributes. Reason is that the creation is irreversable, and slows down execution. This speeds up crypto.js by 10% Change-Id: I2e5472575479a5f2dbe53f59ecb8ed3aeab1be7a Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

| | | | | | | | | | | Checks for strict (not) equal to null, undefined, or a boolean value can be generated without reserving extra registers, or doing a call. This reduces the amount of runtime calls from >25mln to ~6500 for v8-bench.js Change-Id: If08d1124b2869227654b1233a89833c5b5e7b40c Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Change exception handling APISimon Hausmann2013-10-021-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the exception handling API in the engine slightly, encapsulating any use of direct throw statements and catch blocks with concrete types. In the future we need to be able to change the way these are implemented, in order to ensure that the correct stack unwinding code is triggered for throw and re-throw. This patch separates the C++ exception object thrown from the V4 exception (that includes value, throwing context pointer) and stores the latter inside the engine. In order for that to compile, ExecutionEngine::StackTrace and StackFrame had to move into the QV4 namespace directly. In addition the syntax for catching exceptions changes from try { ... } catch (QV4::Exception &ex) { ex.accept(context); QV4::ScopedValue exceptionValue(scope, ex.value()); } to try { ... } catch (...) { QV4::ScopedValue exception(scope, context->catchException()); } Context::catchException() checks if there's a "current" exception in the engine, and if not assumes that we caught an unrelated exception and consequently re-throws. partiallyUnwind() is also gone and replaced with rethrowException(), in order to encapsulate the re-throw. Lastly, in the future nesting try/catch blocks isn't going to be possible due to limitations in the common C++ ABI with regards to foreign exceptions.
