| | | | | | | | | | 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 Verbruggen2015-01-121-5/+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 Yarr JIT: push/pop addressTempRegister.Erik Verbruggen2014-06-051-0/+2
| | | | | | | | | | | Change 6572d4e50d73ac60a8974d07de74c27a7f99ebef moved the addressTempRegister from r3 to r10, so that calculated calls would not overwrite the fourth argument of a call. However, JSC's Yarr JIT might also use it for certain loads, so it also needs to save r10.

* Fix failing assertion with MSVC in debug builds in various testsSimon Hausmann2013-06-261-1/+1
| | | | | | | | | | | | | | We re-implemented Vector::begin() and end() by means of dereferencing the return value from std::begin() and then taking the address of it. That causes a failing assertion in MSVC's STL (rightly so!). We did this only to avoid modifying the original YarrJIT.cpp code. This patch instead simplifies our Vector.h stub again and just fixes the two small occurrences in YarrJIT.cpp where it expects vector->begin() to return a pointer instead of an iterator.

* WTF/JSC update to r148273Simon Hausmann2013-04-127-142/+153
| | | | | | | | | | | | | This brings in various bug fixes in the ARM and MIPS assemblers as well as a Yarr crash fix and performance fix. This change doesn't compile as-is, but the next change will apply the modifications necessary to compile. That'll make future updates easier as it allows for cherry-picking because the modifications are usually always the same.
