* radeonsi: rework how shader pointers to descriptors are setMarek Olšák2015-07-235-91/+156
| | | | | | | | | | | | | | | | | This is mainly needed for tessellation where a VS can be bound as VS, ES, or LS, and TES (tess. evaluationshader) can be bound as VS or ES or neither. Therefore we need the ability to move pointers to descriptors between shaders arbitrarily. The idea is that the context has a mapping from PIPE_SHADER_x to SPI_SHADER_USER_DATA_x. After a shader is enabled or disabled, si_shader_change_notify should be called to update this mapping accordingly. There is a dirty flag for each shader pointer, but only one emit function for all pointers in the whole context, whose code and logic is separated from descriptors.

* gallium/radeon: expose LLVM functions implementing emit_storeMarek Olšák2015-07-232-5/+13
| | | | | | | | emit_store will be reimplemented for tessellation control shader outputs where only radeon_llvm_saturate will be used, but radeonsi will want to fall back to radeon_llvm_emit_store for other register types. This exposes both functions.

| | | | | | | | | | | | | Tessellation control outputs can be read in directly without first having been written. Accessing these will require some special logic anyways, so just let them through.

* glsl: add the tessellation extension to the list for the "layout" qualifierMarek Olšák2015-07-231-1/+2
| | | | | | | | | | | | | | | | This is technically not needed, but it makes the compiler return a better error message if tessellation is used with GLSL < 1.50. Instead of: error: syntax error, unexpected NEW_IDENTIFIER, expecting $end It returns: error: #version 150 layout qualifier `triangles' used And the tessellation spec says: OpenGL 3.2 and GLSL 1.50 are required.
