Clang can generate R_RISCV_CALL_PLT relocations to _mcount:
$ llvm-objdump -dr build/riscv/init/main.o | rg mcount
000000000000000e: R_RISCV_CALL_PLT _mcount
000000000000004e: R_RISCV_CALL_PLT _mcount
After this, the __start_mcount_loc section is properly generated and
function tracing still works.

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.
