* 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: add Aarch64/ARM64 support.Erik Verbruggen2016-01-196-7/+7287
| | | | | | | | | | 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. Change-Id: I650e15fec03c27d4b326a2d70863a89b85cfc5c3 Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>

* | V4 JIT: ARM: move registers around.Erik Verbruggen2015-01-122-3/+3
|/ | | | | | | | | | | | | | | | In 6572d4e50d73ac60a8974d07de74c27a7f99ebef we moved the addressTempRegister to r10, and in d8b276a59402cbbe6d070ba38805350e7f3dd8a1 we made sure that the YarrJIT saves it too. JSC solved this by moving it to r6, which is already saved by the YarrJIT. To make a future update of the assembler easier, we also move it to r6. This requires that we move our scratch register too. 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.

* V4 JIT: tune generated instructions for inplace binopsErik Verbruggen2014-08-121-0/+18
| | | | | | | | | | Generate better code for in-place binary operations where the right-hand side is either a constant or a memory address. Now that the JIT can do this, also tell the register allocator not to un-spill that right-hand side.

* V4: fix register usage on ARM.Erik Verbruggen2014-04-171-1/+1
| | | | | | | | | | | JSC was using r3 as the address scratch register, which collides with the 4th parameter in a function call. This sometimes shows up when generateFunctionCall needs to do a calulated jump. Also fix the usage of r11, which seems to be the fp on some platforms.

| | | | | | | | | | | We want to allow intermixing thumb and ARM for all builds, not only Android. Modified the macro to do a thumb-compatible null pointer check. This also works around a miscompilation on QNX where the compiler appeared to make incorrect assumptions about the address of functions we are taking.

* Speed up stack trace generation for the JITSimon Hausmann2013-10-162-0/+10
| | | | | | | | | | | | | | It turns out that in QML it is not unusual that during early binding evaluations due to the undefined order, the evaluation tries to look up properties in objects that aren't initialized yet and thus exceptions are thrown. Eeach thrown exception saves a stack trace, which is expensive to generate when using the JIT, as it does full stack unwinding. This patch implements a more light-weight approach by storing the instruction pointer in the context before leaving JIT generated code.
