--- Comment #5 from Eero Tamminen <eero.t.tamminen at intel.com> ---
On HSW GT3e, this change drops 3Dgeeks' GpuTest geometry instancing test
performance to 10% of the performance without the indicated change:
  MESA_GL_VERSION_OVERRIDE=3.0 ./GpuTest /test=gi

(This is unrelated to the rendering error regression visible in the test, I saw
that also with 2014-06-27 git version of Mesa.)
