Currently maximum JITed code size is limited to 64k, because JIT can emit only relative short branches, whose range is limited by 64k in both directions. Teach JIT to use relative long branches. There are no compare+branch relative long instructions, so using relative long branches consumes more space due to having to having to emit an explicit comparison instruction. Therefore do this only when relative short branch is not enough.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
