glean pixelFormats now fails but previously passed.

$ glean -r results -t pixelFormats
pixelFormats failed at pixel (0,0), color channel 0:
  Expected: 0xff 0xff 0xff 0xff
  Found:    0xf0 0xf0 0xf0 0xff
  Format: GL_RGBA
  Type: GL_UNSIGNED_BYTE

    mesa: implement new texture format AL44
    
    Radeon GPUs can do this. R600 can even do render-to-texture.
    Packing and extracting aren't implemented, but we shouldn't hit them (I think).
    Tested with swrast, softpipe, and r300g.

bisect run success

Comment 3 Marek Olšák 2011-01-08 13:43:48 UTC

Sorry I couldn't notice this regression because swrast fails glean/pixelFormats badly here:

pixelFormats:  FAIL rgba8, db, z24, s8, win+pmap, id 33
	4628 tests passed, 7204 tests failed.
