* | V4: Tweak "enable JIT" ifdefs.Erik Verbruggen2016-01-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | - 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>

| | | | | | | | | | | | | | | | | | | | This uses the JavaScriptCore assembler rev. 195098. It is tested on iOS (for which it is disabled, as it only allows marking pages as executable when running from Xcode). Testing on Linux will be done when hardware arrives.

* | WinRT: Enable JIT for x86/x64 target platformsMaurice Kalinowski2016-01-165-10/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

But, because it is used a lot, we don't want it above r7 for Thumb2 reasons. Therefore, we move the engine to r10, and the scratch register to r5.
