The vendor has long since switched to Arm, with the last product reaching their official end-of-life over 11 years ago. Linux support for the ISA was dropped 7 years ago. More importantly, this architecture was never supported by upstream GCC, and the vendor fork is stuck at version 4.2, which FFmpeg no longer supports (as per C11 requirement). Presumably, this is still the case given the lack of vendor support. Indeed all of the code being removed here consisted of inline assembler scalar optimisations. A sane C compiler should be able to perform those automatically nowadays (with the sole exception of fast CLZ detection), but this is moot as this architecture is evidently dead.
