Message : Forcefully disable RVV intrinsics usage in llama.cpp/libggml. The code assumes that if __riscv_v_intrinsic is defined the various RVV intrinsics are available and usable. With clang the intrinsics may be available even though actual usage of said intrinsics has to be allowed with clang -march=... or function annotations. Also the code assumes that if it can use said intrinsics at compile time then they ought to be used at runtime. This is false on OpenBSD which doesn't require the cpu to support the V extension. Example error at compile time: .../firefox-154.0/third_party/llama.cpp/ggml/src/ggml-cpu/vec.cpp:407:22: error: RISC-V type 'vfloat32m2_t' (aka '__rvv_float32m2_t') requires the 'zve32f' extension 407 vfloat32m2_t vx = __riscv_vle32_v_f32m2(&x[i], vl); With & ok landry@ (maintainer)
