    i965: Enable EXT_shader_samples_identical · 99840eb9
    Ian Romanick authored
    On the vec4 backend, textureSamplesIdentical() will always return
    false.  There are currently no test cases for the vec4 backend, so we
    don't have much confidence in any implementation.  We also don't think
    anyone is likely to miss it.
    v2: Handle immediate value for MCS smarter.  Rebase on changes to
    nir_texop_sampels_identical (missing second parameter).  Suggested by
    v3: Add Neil's code to handle 16x MSAA in the FS.  Also rebase on top of
    f9a9ba5e.  Stub out the vec4 implementation.
