Hi all,
As part of the kernel build process several intermediate files are created, for several reasons: mainly because our verification toolchain currently requires the kernel as 1 C file, and to support the bitfield generator, which generates the minimal code and proofs for various data structures.
Take a look at CMakeLists.txt [1] to see where these files are generated and for more context.
Thanks
Anna.

Hi Elinor,
From my understanding of trying SEL4 on FPGA/Qemu. This is a folder that is created once you compile the sel4 project.
Actually speaking, you need not worry about it. All these are generated files during compilation

Within the build directory I created, there's a kernel directory. In that directory, there are a bunch of C files with names that include "wrapper." For instance, there's a file named kernel_all_pp_prune_wrapper_temp.c. I'm having trouble understanding what the wrapper files do. Are there for testing, or something else?
