<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>
