Allow to verify jit behaviour by writing tests as below:
SEC("tp")
__arch_x86_64
__jited(" endbr64")
__jited(" nopl (%rax,%rax)")
__jited(" xorq %rax, %rax")
...
__naked void some_test(void)
{
asm volatile (... ::: __clobber_all);
}
Allow regular expressions in patterns, same way as in __msg.
By default assume that each __jited pattern has to be matched on the
next consecutive line of the disassembly, e.g.:
__jited(" endbr64") # matched on line N
__jited(" nopl (%rax,%rax)") # matched on line N+1
If match occurs on a wrong line an error is reported.
To override this behaviour use __jited("..."), e.g.:
__jited(" endbr64") # matched on line N
__jited("...") # not matched
__jited(" nopl (%rax,%rax)") # matched on any line >= N

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 reStructuredText 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.
