[Bf-committers] Blender 2.79a failed to build with gcc 8.0.1

[Sergey Sharybin]

Hi,

You should be able to fix this compilation error by changing it to: return
_mm_castsi128_ps(_mm_shuffle_epi32(a, _MM_SHUFFLE(i3, i2, i1, i0)));

Patch version is: https://hastebin.com/efopofoboy.diff

Let me know if it indeed fixes the problem.
