At the moment, we only do extra sub-register mode compilation on bpf object files used by "test_progs". These object files are really loaded and executed. This patch further extends sub-register mode compilation to all bpf object files, even those without corresponding runtime tests. Because this could help testing LLVM sub-register code-gen, kernel bpf selftest has much more C testcases with reasonable size and complexity compared with LLVM testsuite which only contains unit tests. There were some file duplication inside BPF_OBJ_FILES_DUAL_COMPILE which is removed now.

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.
