* nir/spirv: Allow loop breaks in a switch body.Bas Nieuwenhuizen2017-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | Per the SPIR-V spec 2.11 Structured Control Flow: "The only blocks in a construct that can branch outside the construct are ... - a break block for the innermost loop it is inside of. ..." With "Break block: A block containing a branch to the Merge Block of a loop header's merge instruction." Note that it puts no restriction on not being in an if or switch within the innermost loop. This passes the loop_break block to the switch body so it can properly detect loop breaks. CC: <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | | | When a conditional branch has the same labels in the "if" part and in the "else" part, then we have the same cfg block, and it must be handled once. v2: handle it the same way as OpBranch (Jason).

* nir/spirv: Simplify matrix loads/storesJason Ekstrand2017-07-052-100/+90
| | | | | | | | | | | | | | | | | | | | | Instead of handling all of the complexity at the end, we choose to decorate types a bit more cleverly. When we have a row-major matrix type, we give it the stride of a single vector and give it's array element type (which represents a column) the actual matrix stride. Previously, we were using stop_at_matrix and handling everything from matrix on down as special cases but now we walk the access chain all the way to the end and then load. Even though this looks like it may lead to a significant functional change, it doesn't. The reason why we needed to do stop_at_matrix before was to handle row-major properly since the offsets and strides would be all out-of-order. Now that row major matrix types have the small stride on the matrix and the large stride on the vector, offsetting to a single column of a row-major matrix works fine. The load/store code simply picks up on the fact that the stride isn't the type size and does multiple loads. The generated code from these methods should be the same.

* nir/spirv: Wrap access chains in a new vtn_pointer data structureJason Ekstrand2017-07-054-159/+187
| | | | | | | | | | | | The vtn_pointer structure provides a bit better abstraction than passing access chains around directly. For one thing, if the pointer just points to a variable, we don't need the access chain at all. Also, pointers know what their dereferenced type is so we can avoid passing the type in a bunch of places. Finally, pointers can, in theory, be extended to the case where you don't actually know what variable is being referenced. Reviewed-by: Connor Abbott <[email protected]>

| | | | | | | | | | | | | | | Before, we were just implementing it with a move, which is incorrect when the source and destination have different bitsizes. To implement it properly, we need to use the 64-bit pack/unpack opcodes.

* spirv: Work around the Doom shader bugJason Ekstrand2017-06-202-0/+28
| | | | | | | | | | | | | | | | | Doom shipped with a broken version of GLSLang which handles samplers as function arguments in a way that isn't spec-compliant. In particular, it creates a temporary local sampler variable and copies the sampler into it. While Dave has had a hack patch out for a while that gets it working, we've never landed it because we've been hoping that a game update would come out with fixed shaders. Unfortunately, no game update appears on to be on the horizon and I've found this issue in yet another application so I think we're stuck working around it. Hopefully, we can delete this code one day.

* nir: Embed the shader_info in the nir_shader againJason Ekstrand2017-05-092-31/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info from being embedded into being just a pointer. The idea was that sharing the shader_info between NIR and GLSL would be easier if it were a pointer pointing to the same shader_info struct. This, however, has caused a few problems: 1) There are many things which generate NIR without GLSL. This means we have to support both NIR shaders which come from GLSL and ones that don't and need to have an info elsewhere. 2) The solution to (1) raises all sorts of ownership issues which have to be resolved with ralloc_parent checks. 3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been using nir_gather_info to fill out the final shader_info. Thanks to cloning and the above ownership issues, the nir_shader::info may not point back to the gl_shader anymore and so we have to do a copy of the shader_info from NIR back to GLSL anyway. All of these issues go away if we just embed the shader_info in the nir_shader. There's a little downside of having to copy it back after calling nir_gather_info but, as explained above, we have to do that anyway.
