* i965/vec4: Don't unspill the same register in consecutive instructionsIago Toral Quiroga2015-09-041-8/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have spilled/unspilled a register in the current instruction, avoid emitting unspills for the same register in the same instruction or consecutive instructions following the current one as long as they keep reading the spilled register. This should allow us to avoid emitting costy unspills that come with little benefit to register allocation. v2: - Apply the same logic when evaluating spilling costs (Curro). v3: - Abstract the logic that decides if a register can be reused in a function. that can be used from both spill_reg and evaluate_spill_costs (Curro). v4: - Do not disallow reusing scratch_reg in predicated reads (Curro). - Track if previous sources in the same instruction read scratch_reg (Curro). - Return prev_inst_read_scratch_reg at the end (Curro). - No need to explicitily skip scratch read/write opcodes in spill_reg (Curro). - Fix the comments explaining what happens when we hit an instruction that does not read or write scratch_reg (Curro) - Return true early when the current or previous instructions read scratch_reg with a compatible mask. v5: - Do not return true early, the loop should not be expensive anyway and this adds more complexity (Curro).

| | | | | | | | | | | | | | | | | According to the GLSL 1.50 specification, page 76: "The shader must also set all values in gl_ClipDistance that have been enabled via the OpenGL API, or results are undefined." With this patch, we only enable clip distance writes when the shader actually writes them. We no longer force a value to be written when clip planes are enabled in the API. This could mean the first varying slot would be used as clip distances - I believe it should be the safe kind of undefined behavior. Empirically, it doesn't seem to cause a problem.

* i965: Delete the brw_vue_program_key::userclip_active flag.Kenneth Graunke2015-09-035-22/+15
| | | | | | | | | | | | | | | | | There are two uses of this flag. The primary use is checking whether we need to emit code to convert legacy gl_ClipVertex/gl_Position clipping to clip distances. In this case, we also have to upload the clip planes as uniforms, which means setting nr_userclip_plane_consts to a positive value. Checking if it's > 0 works for detecting this case. Gen4-5 also wants to know whether we're doing clipping at all, so it can emit user clip flags. Checking if output_reg[VARYING_SLOT_CLIP_DIST0] is set to a real register suffices for this.

* i965: Remove legacy clip plane handling from geometry shaders.Kenneth Graunke2015-09-033-33/+8
| | | | | | | | | | | | | | | | | | We only support geometry shaders in core profiles, where gl_ClipVertex doesn't exist. Presumably the even older behavior of clipping to gl_Position isn't supported either. In fact, GLSL 1.50 page 76 claims: "The shader must also set all values in gl_ClipDistance that have been enabled via the OpenGL API, or results are undefined." So we don't need to handle legacy clipping in geometry shaders. I think Paul added this back when we were considering supporting the old GL_ARB_geometry_shader4 extension.

* i965/gen9: Annotate input coverage mask changeBen Widawsky2015-09-032-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | As far as I can tell, the behavior is preserved from the previous generations. Before we set a single bit to tell the FS whether or not we'll be using an input coverage mask. Now we have some options which are implementing various extensions. These bits are used for the various conservative rasterization mechanisms (for collision detection, binning, and whatever else). I believe that the behavior is preserved because the problem which conservative rasterization is attempting to fix would go away with the "NORMAL" mode (at the cost of performance, I believe). This patch serves as documentation of the change by creating the enums, as well as giving some of the history with the links here so that the next person who comes along and looks at it doesn't spend as long as I had to in order to determine if there is an issue or not. Previously, this algorithm had been done in software, and this can still be used as long as we don't export an extension stating otherwise.
