* Enable V4 JIT for aarch64Laszlo Agocs2016-02-011-1/+1
| | | | | | | | | | 64-bit ARM boards (f.ex. with Tegra X1) are becoming common and therefore enabling the JIT would be highly beneficial.

* V4: Tweak "enable JIT" ifdefs.Erik Verbruggen2016-01-201-11/+16
| | | | | | | | | | | - indentation, to make it readable - on arm64: only enable for Linux (but only after future testing!) - add CONFIG+=force-compile-jit handling so the JIT can be compiled/used even on platforms that don't officially support it (like iOS, where it works if you run from Xcode). This is done for debugging purposes. Change-Id: I8611ba409e10305f480463a16d88bc854b1c218a Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>

* WinRT: Enable JIT for x86/x64 target platformsMaurice Kalinowski2016-01-161-1/+1
| | | | | | | | | | | | | | | | | | | | | This only works for Windows 10 and later. Setting the "Code Generation" capability in the manifest, WinRT applications can use JIT for Windows 10 Desktop. Update the Allocator in regards to this and also update the VirtualProtectFromApp section. When the engine gets initialized, check for marking an area as executable. If it fails, fallback to interpreter mode. This does not affect ARM platforms, as we do not have calling conventions yet. It is implicitly disabled as V4_ENABLE_JIT is not defined.

* | Fix usage of QtQmlDevTools private headers on OSX with framework buildsSimon Hausmann2015-03-161-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously this module borrowed its private headers from QtQml, so that when writing QT += qmldevtools-private, you'd get the private headers from QtQml. This doesn't work when QtQml is built as a framework. A cleaner solution is to give this module its headers proper by letting syncqt create the forwarding headers correctly (and consequently also include them in make install). In order for this to work, the included headers themselves cannot include any headers from QtQml, which this patch also takes care of, through a centralized inclusion of qv4global_p.h.

* 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.
