lld-link: error: undefined symbol: _mm_set_ps

Question

I'm trying to use SIMD intrinsics on Clang compiler for Windows and I'm getting undefined symbol error. What am I missing? There is no such a library for intrinsics, the compiler should just know how to put them into the code.

I'm also getting this erro with the MSVC linker.

Just a example code.

#include <xmmintrin.h>

extern inline float
pmath_Sinf(float radians)
{
  __m128 radians_ps = _mm_set_ps(0.0f, 0.0f, 0.0f, radians);

  return 0.0f;
}

extern inline float
pmath_Cosf(float radians)
{
  __m128 radians_ps = _mm_set_ps(0.0f, 0.0f, 0.0f, radians);

  return 0.0f;
}

These are the command line output with verbosity.

Answer 1

I got it working.

Since I have both Clang and MSVC installed, both of them has its own xmmintrin.h header file in their include path, since it is compiler specific. I realized that with #include <xmmintrin.h>, Clang was including the MSVC version, probably because it found first in the PATH. So all I did was use /X compiler option that makes it stoping searching for include paths, and I created a new xmmintrin.h file by coping and pasting all I needed from the actual Clang xmmintrin.h into it.

Thanks everyone for your comments.
