The assembly kernels use only baseline instructions for their architecture:
The kernel backends use only baseline instructions for their architecture:
* `src/fossmark.S` uses ARMv8-A and NEON under AAPCS64.
* `src/fossmark_x86_64.S` uses baseline x86-64 and SSE2 under the System V ABI.
* `src/fossmark_ppc32.c` is endian-safe and uses baseline 32-bit PowerPC operations. It avoids AltiVec so it runs on the Wii's PowerPC 750CL-class CPU.
The kernel files contain no system calls or calls into the C library. The same
ARM64 source can be assembled for Linux, macOS, Windows, and BSD object formats.
