After llvm/llvm-project#195486 , LLVM has explicit handling for null pointers in simd operations instead of using special handling based on zeroes. This causes LLVM with asserts enabled to detect an improperly typed mask passed to splat (if the output vector does not have i32 elements), and can cause SIGSEGV in more complex cases with asserts disabled.

@jhpratt Can you explain how this change could be connected to the wasi failure in the tests? This change adjusts how simd is done. The wasi failure has no vectorized IR as far as I can see? |
