* Move the vtable pointer from the object to the internal classLars Knoll2013-12-041-0/+2
| | | | | | | | This saves one pointer per object, and willmake other optimizations easier in the future. Change-Id: I1324cad31998896b5dc76af3c8a7ee9d86283bfe Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Fix ARM thumb2 mode detectionSimon Hausmann2013-10-171-1/+5
| | | | | | | | | __TARGET_ARCH_THUMB may not always be defined, but __thumb2__ for example is also a good indicator that we can generated and run thumb2 code and thus enable the JIT. Change-Id: I987d0af5883d9bb844c4c99a0691a12aedc94ff5 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Fix build on ARM in ARM mode (instead of thumb2)Simon Hausmann2013-10-171-0/+31
| | | | | | | | | | We don't support the traditional ARM assembler (yet), only JIT on thumb2. In order for us to reliably check that, we have to wait until the pre-processor runs, which this patch achieves by moving all JIT enable/disable decisions into qv4global_p.h Change-Id: I7eff5b4fbf1cd26297a08dee16984ad867358113 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Change exception handling APISimon Hausmann2013-10-021-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Use a handwritten offsetof macroLars Knoll2013-09-201-0/+2
| | | | | | | | | | clang complains about our usage of offsetof(). What we do is not strictly c++98 compliant, but compliant with c++11. So replace the default offsetof with a handwritten macro to shut up clang until we can switch to c++11 mode for all compilers.

* Fix compilation with MSVC 2008 (and prospective Windows CE build fix)Simon Hausmann2013-08-221-0/+3
| | | | | | | | | | | | | | | | | * Only 2010 and newer ship stdint.h, so for 2008 we have to provide a little stdint.h compat header, for some of the third-party code we import. Our own Qt code this patch changes to use quint* types instead. * Include math.h and float.h for some math functions. * disable the JIT on Windows CE for now. * Change use of intptr_t to qintptr in Qt code. intptr_t is in inttypes.h, except that with VS 2008 it is indirectly available through stdio.h. Let's avoid the mess and just use the qt type, that's always available. Change-Id: I19055edd89e0a6b147d9edbb3b711798ed3c05a5 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Fix build on QNXSimon Hausmann2013-08-121-0/+8
| | | | | | | | | | | There is std::isnan and friends, but math.h also defines isnan as macro, so std::isnan expands to std::whateverthemacrois and that fails to build. So include math.h early on, get rid of the macros and then we can continue to use std::isnan throughout the code base safely.
