--- Comment #13 from Martin Liška <marxin at gcc dot gnu.org> ---
There's a reduced test-case:

#pragma GCC target "avx"
typedef float __m256 __attribute__((__vector_size__(32)));
__m256 _mm256_blendv_ps___Y, _mm256_blendv_ps___M, _mm256_mul_ps___A,
    _mm256_mul_ps___B, IfThenElse___trans_tmp_9;
struct Raw256 {
  using type = __m256;
};
struct Vec256 {
  using Raw = Raw256::type;
  Raw raw;
} UndoXYBInPlace_linear_g;
Vec256 IfThenElse(Vec256 no) {
  IfThenElse___trans_tmp_9 = __builtin_ia32_blendvps256(
      no.raw, _mm256_blendv_ps___Y, _mm256_blendv_ps___M);
  return {IfThenElse___trans_tmp_9};
}
Vec256 operator*(Vec256, Vec256) {
  __m256 __trans_tmp_11 = _mm256_mul_ps___A * _mm256_mul_ps___B;
  return {__trans_tmp_11};
}
struct TF_SRGB {
  template <class D, class V> void EncodedFromDisplay(D, V x) {
    Vec256 __trans_tmp_12, linear = x * __trans_tmp_12;
    IfThenElse(linear);
  }
};
#pragma GCC target
