* nir: Store num_direct_uniforms in the nir_shader.Kenneth Graunke2015-04-111-0/+3
| | | | | | | | | | | | | | Storing this here is pretty sketchy - I don't know if any driver other than i965 will want to use it. But this will make it a lot easier to generate NIR code at link time. We'll probably rework it anyway. (Ian suggested making nir_assign_var_locations_scalar_direct_first simply modify the nir_shader's fields, rather than passing pointers to them. If this stays long term, we should do that. But Jason and I suspect we'll be reworking this area again in the near future.)

* nir: fix bit of cargo-culting in lower_idivRob Clark2015-04-111-2/+0
| | | | | | | | | | | | I guess I was looking too much at how lower_system_values worked when writing lower_idiv. Since ttn wasn't emitting load_var for sysvals and the only drivers using lower_idiv were using ttn, I think nothing was broken as a result. But might as well fix this before it becomes a problem.

* nir: Implement a nir_sweep() pass.Kenneth Graunke2015-04-073-0/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This pass performs a mark and sweep pass over a nir_shader's associated memory - anything still connected to the program will be kept, and any dead memory we dropped on the floor will be freed. The expectation is that this will be called when finished building and optimizing the shader. However, it's also fine to call it earlier, and many times, to free up memory earlier. v2: (feedback from Jason Ekstrand) - Skip sweeping impl->start_block, as it's already in the CF list. - Don't sweep SSA defs (they're owned by their defining instruction) - Don't steal phi sources (they're owned by nir_phi_instr). - Don't steal tex->src (it's owned by the tex_inst itself) - Don't sweep dereference chains (top-level dereferences are owned by the instruction; sub-dereferences are owned by the parent deref). - Don't sweep sources and destinations (SSA defs are handled as part of the defining instruction, and registers are handled as part of function implementations). - Just steal instructions; don't walk them (no longer required). v3: (feedback from Jason Ekstrand) - Steal indirect sources from nir_src/nir_dest.

* nir: Allocate dereferences out of their parent instruction or deref.Kenneth Graunke2015-04-075-37/+41
| | | | | | | | | | | | | | | | | | | | | | | | | Jason pointed out that variable dereferences in NIR are really part of their parent instruction, and should have the same lifetime. Unlike in GLSL IR, they're not used very often - just for intrinsic variables, call parameters & return, and indirect samplers for texturing. Also, nir_deref_var is the top-level concept, and nir_deref_array/nir_deref_record are child nodes. This patch attempts to allocate nir_deref_vars out of their parent instruction, and any sub-dereferences out of their parent deref. It enforces these restrictions in the validator as well. This means that freeing an instruction should free its associated dereference chain as well. The memory sweeper pass can also happily ignore them. v2: Rename make_deref to evaluate_deref and make it take a nir_instr * instead of void *. This involves adding &instr->instr everywhere.

| | | | | | | | | | | | | | Commit 18004c3 introduced more restrictive validation to linker between inputs and outputs. This patch skips the additional check for programs that utilize GL_ARB_separate_shader_objects, there inputs and outputs might not make exact match during linking but only when constructing the final pipeline. This made some of the GL_ARB_program_interface_query tests shaders fail to link, these tests can be used to verify the change.
