Not sure if this is intel specific or not, but either way I don't feel responsible for this bug. Agreed. I was hoping it was weird enough to pique your interest. Is this still an issue? I'm not able to reproduce this on my SKL. I can't repro this anymore either. |

The following piglit tests fail on all Intel hardware, with -O0: piglit.spec.ext_texture_compression_s3tc.fbo-generatemipmap-formats piglit.spec.ext_texture_srgb.fbo-generatemipmap-formats-s3tc EG: piglit/bin/fbo-generatemipmap-formats GL_EXT_texture_compression_s3tc -auto -fbo Using test set: GL_EXT_texture_compression_s3tc Testing GL_COMPRESSED_RGB_S3TC_DXT1_EXT PIGLIT: {"subtest": {"GL_COMPRESSED_RGB_S3TC_DXT1_EXT" : "pass"}} Testing GL_COMPRESSED_RGBA_S3TC_DXT1_EXT PIGLIT: {"subtest": {"GL_COMPRESSED_RGBA_S3TC_DXT1_EXT" : "pass"}} Testing GL_COMPRESSED_RGBA_S3TC_DXT3_EXT PIGLIT: {"subtest": {"GL_COMPRESSED_RGBA_S3TC_DXT3_EXT" : "pass"}} Testing GL_COMPRESSED_RGBA_S3TC_DXT5_EXT PIGLIT: {"subtest": {"GL_COMPRESSED_RGBA_S3TC_DXT5_EXT" : "pass"}} Testing GL_COMPRESSED_RGB_S3TC_DXT1_EXT (NPOT) PIGLIT: {"subtest": {"GL_COMPRESSED_RGB_S3TC_DXT1_EXT NPOT" : "pass"}} Testing GL_COMPRESSED_RGBA_S3TC_DXT1_EXT (NPOT) PIGLIT: {"subtest": {"GL_COMPRESSED_RGBA_S3TC_DXT1_EXT NPOT" : "pass"}} Testing GL_COMPRESSED_RGBA_S3TC_DXT3_EXT (NPOT) PIGLIT: {"subtest": {"GL_COMPRESSED_RGBA_S3TC_DXT3_EXT NPOT" : "pass"}} Testing GL_COMPRESSED_RGBA_S3TC_DXT5_EXT (NPOT) Probe color at (439,4) Expected: 0 255 0 63 Observed: 0 255 0 255 PIGLIT: {"subtest": {"GL_COMPRESSED_RGBA_S3TC_DXT5_EXT NPOT" : "fail"}} PIGLIT: {"result": "fail" } When Mesa is compiled with -O2, the tests pass. You would expect optimizations to *break* tests, not fix them. ¯\_(ツ)_/¯
