Fix crash in JIT::DFG::prepareOSREntry

2015-04-01T11:54:08+00:00

While verifying predictions in prepareOSREntry, locals could lay
outside the stack in some cases. So we shouldn't retrieve jsValue
from locals when we don't have to.

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.

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.
