Summary: NNC's LLVM backend only ever reached Sleef on x86. Two things blocked aarch64, and either one alone was sufficient: intrinsic_symbols.cpp registers the Sleef_* symbols with the JIT inside a #if !defined(_MSC_VER) && defined(__x86_64__) block, so on aarch64 the JIT knew about no vector math symbols at all. getSimdFunction() gated vectorized lowering on the target feature string containing +avx , which is nev…
