        <pre>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

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"}}

PIGLIT: {"result": "fail" }

When Mesa is compiled with -O2, the tests pass.

You would expect optimizations to *break* tests, not fix them.  ¯\_(ツ)_/¯</pre>
