* nir: Vectorize intrinsicsJason Ekstrand2015-01-158-267/+107
| | | | | | | | | | We used to have the number of components built into the intrinsic. This meant that all of our load/store intrinsics had vec1, vec2, vec3, and vec4 variants. This lead to piles of switch statements to generate the correct intrinsic names, and introspection to figure out the number of components. We can make things much nicer by allowing "vectorized" intrinsics. Reviewed-by: Connor Abbott <[email protected]>

* nir/glsl: Generate SSA NIRJason Ekstrand2015-01-151-129/+117
| | | | | | | | | With this commit, the GLSL IR -> NIR pass generates NIR in more-or-less SSA form. It's SSA in the sense that it doesn't have any registers, but it isn't really useful SSA because it still has a pile of load/store intrinsics that we will need to get rid of.

* nir: Add a pass to lower local variable accesses to SSA valuesJason Ekstrand2015-01-153-0/+1069
| | | | | | | | | This pass analizes all of the load/store operations and, when a variable is never aliased (potentially used by an indirect operation), it is lowered directly to an SSA value. This pass translates to SSA directly and does not require any fixup by the original to-SSA pass. Reviewed-by: Connor Abbott <[email protected]>

* nir/from_ssa: Don't lower constant SSA values to registersJason Ekstrand2015-01-151-8/+32
| | | | | | | | | | | Backends want to be able to do special things with constant values such as put them into immediates or make decisions based on whether or not a value is constant. Before, constants always got lowered to a load_const into a register and then a register use. Now we leave constants as SSA values so backends can special-case them if they want. Since handling constant SSA values is trivial, this shouldn't be a problem for backends. Reviewed-by: Connor Abbott <[email protected]>
* nir: Add a basic CSE passJason Ekstrand2015-01-153-0/+272

| | | | | | | | The unlink_blocks function moves successors around to make sure that, if there is a remaining successor, it is in the first successors slot and not the second. To fix this, we simply get both successors up front. Reviewed-by: Connor Abbott <[email protected]>
* nir: Differentiate between signed and unsigned versions of find_msbJason Ekstrand2015-01-152-5/+22
| | | | | | | | | | | We also make the return types match GLSL. The GLSL spec specifies that findMSB and findLSB return a signed integer. Previously, nir had them return unsigned. This updates nir's behavior to match what GLSL expects. We also update the nir-to-fs generator to take the new instructions. While we're at it, we fix the case where the input to findMSB is zero.

| | | | | | | This pass is kind of stupidly implemented but it should be enough to get us up and going. We probably want something better that doesn't generate all of the redundant moves eventually. However, the i965 backend should be able to handle the movs, so I'm not too worried about it in the short term.
