* mesa: add scaffolding for OES/EXT_primitive_bounding_boxIlia Mirkin2016-08-302-0/+6

* glsl: Fix gl_program::OutputsWritten computation for dual-source blending.Francisco Jerez2016-08-301-1/+1
| | | | | | | | | | | | | | | | | | | | In the fragment shader OutputsWritten is a bitset of FRAG_RESULT_* enumerants, which represent the location of each color output written by the shader. The secondary and primary color outputs of a given render target using dual-source blending have the same location, so the 'idx' computation below will give the wrong bit as result if the 'var->data.index' term is non-zero -- E.g. if the shader writes the primary and secondary colors of the FRAG_RESULT_COLOR output, ir_set_program_inouts will think that the shader writes both FRAG_RESULT_COLOR and FRAG_RESULT_SAMPLE_MASK, which is just bogus. That would cause the brw_wm_prog_key::nr_color_regions computation done in the i965 driver during fragment shader precompilation to be wrong, which currently leads to unnecessary recompilation of shaders that use dual-source blending, and triggers an assertion failure in fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.

* glsl: Fix incorrect hard-coded location of the gl_SecondaryFragColorEXT ↵Francisco Jerez2016-08-301-7/+2
| | | | | | | | | | | | | | | | | | | built-in. gl_SecondaryFragColorEXT should have the same location as gl_FragColor for the secondary fragment color to be replicated to all fragment outputs. The incorrect location of gl_SecondaryFragColorEXT would cause the linker to mark both FRAG_RESULT_COLOR and FRAG_RESULT_DATA0 as being written to, which isn't allowed by the spec and would ultimately lead to an assertion failure in fs_visitor::emit_fb_writes() on my i965-fb-fetch branch. This should also fix the code below for multiple dual-source-blended render targets, which no driver currently supports but we have plans to enable eventually in the i965 driver (the comment saying that no hardware will ever support it seems rather hilarious).
