The test uses bpf_prog_get_info_by_fd() to obtain the xlated instructions of the program first. Since these instructions have already been rewritten by the verifier, the tests then checks whether the rewritten instructions are as expected. And to ensure LLVM generates code exactly as expected, use inline assembly and a naked function.

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.
