        <pre>The macOS binaries hosted on the llvm downloads page have this builtin missing:
__builtin_ia32_cvtdq2ps.

Building from sources on macOS also yields this problem.
Clang 6 on macOS does not have this issue. Clang 7 on linux does not have this
issue.

Test program to reproduce:


int main() {

        __attribute__((__vector_size__(4 * sizeof(int)))) int test;
        __builtin_ia32_cvtdq2ps(test);

        return 0;
}</pre>
