* V4 JIT: ARM: move registers around.Erik Verbruggen2015-01-121-1/+1
| | | | | | | | | | | | | | | | 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 JIT: enable the JIT when compiling with clang on ARM.Erik Verbruggen2014-07-241-0/+1
| | | | | | | | The macros that were used to detect Thumb2 support on the cores were gcc specific. Change-Id: I76959899b41f440d4b7ad7a5436059a3dc102111 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* 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.

* WTF/JSC update to r148273Simon Hausmann2013-04-121-2/+13
| | | | | | | | | | | | | 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.
