Rémi Denis-Courmont 20c8a3f5ff lavu/riscv: fix compilation without Vector support The half-baked assembler in Clang 16 and earlier can't process our RISC-V assembler. This adds yet another work around that. If you must use Clang, please use version 17 or later. (cherry picked from commit `e29432e6bb`)		2024-11-18 20:05:47 +02:00
