Just making sure this test won't be forgotten.
Thanks!

It hanged Intel gen8+ GPUs when discarding fragments and depth test
being enabled.
There is also safeguard against lack of second color output in radeonsi.

  - Set supports_gl_compat_version = 30
  - Moved drawing to piglit_display

[Piglit] [PATCH v3] arb_blend_func_extended: Test dual src blending without second color output

2018-07-09 Thread Danylo Piliaiev 
Using fragment shader without second color output should not hang gpu
when dual source blending is enabled.
It hanged Intel gen8+ GPUs when discarding fragments and depth test
being enabled.
There is also safeguard against lack of second color output in radeonsi.
