Initialize label vector lazily

2015-02-25T09:33:36+00:00

When parsing JSON temporary JIT objects are created when resolving each
id. Each of these get a list of labels initialized to the size of the
codeblock being operated on, which can be very long in some cases.

This patch delays the initialization of the label vector, until it is
actually used which is easy to figure out since the vector is not
exported outside the class.

Update copyright headers

2015-02-16T13:05:16+00:00

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Fix lots of crashes because of 4th argument register trampling.

2015-02-09T16:44:51+00:00

https://bugs.webkit.org/show_bug.cgi?id=123421

Reviewed by Michael Saboff.

r3 register is the 4th argument register for ARM and also a scratch
register in the baseline JIT for this architecture. We can use r6
instead, as this used to be the timeoutCheckRegister and it is no
longer used since r148119.

* assembler/ARMAssembler.h: Temp register is now r6 instead of r3 for ARM.
* assembler/MacroAssemblerARMv7.h: Temp register is now r6 instead of r3 for ARMv7.
* dfg/DFGGPRInfo.h: Add r3 properly in GPRInfo for ARM.
* jit/JITStubs.cpp: Remove obsolete timeoutCheckRegister init.
* yarr/YarrJIT.cpp: Use r3 and not the new scratch register r6 and r8 register
doesn't need to be saved.

Use fixed executable allocator on x64

2014-11-07T11:48:59+00:00

Since the x86-64 assembler generator depends on jumps being expressable
as 32bit offsets we need to use the fixed size executable allocator and
not the on demand allocator. This patch removes its exclusion from being
used on Windows.
