C++ (Cpp) vfmaq_lane_f64 Examples

Example #1

File: arm64_vfma.c Project: VanirLLVM/toolchain_clang

float64x2_t test_vfmaq_lane_f64(float64x2_t a1, float64x2_t a2, float64x1_t a3) {
  // CHECK: test_vfmaq_lane_f64
  return vfmaq_lane_f64(a1, a2, a3, 0);
  // NB: the test below is deliberately lose, so that we don't depend too much
  // upon the exact IR used to select lane 1 (usually a shufflevector)
  // CHECK: llvm.fma.v2f64(<2 x double> %a2, <2 x double> {{.*}}, <2 x double> %a1)
  // CHECK-NEXT: ret
}
