* compiler: Merge shader_info's tcs and tes structs.Kenneth Graunke2017-01-108-32/+34
| | | | | | | | | | | | | | | Annoyingly, SPIR-V lets you specify all of these fields in either the TCS or TES, which means that we need to be able to store all of them for either shader stage. Putting them in a union won't work. Combining both is an easy solution, and given that the TCS struct only had a single field, it's pretty inexpensive. This patch renames the combined struct to "tess" to indicate that it's for tessellation in general, not one of the two stages.

* i965: Fix number of slots in SSO mode when there are no user varyings.Kenneth Graunke2017-01-091-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | We want vue_map->num_slots to be one more than the final slot. When assigning fixed slots, built-in slots, and non-SSO user varyings, we do slot++. This leaves "slot" as one past the most recently assigned slot. But for SSO user varyings, we computed slot based on the varying location value...and left it at that slot value. To work around this inconsistency, I made num_slots be "slot + 1" if separate and "slot" otherwise. The problem is...if there are no user varyings in SSO mode...then we would have done slot++ when assigning built-ins, so it would be off by one. This resulted in loops from 0 to vue_map->num_slots hitting a bonus BRW_VARYING_SLOT_PAD at the end. This used to break the SIMD8 VS/TES backends, but I fixed that in commit 480d6c1653713dcae617ac523b2ca5deee01c845. It's probably safe at this point, but we should fix it anyway. To fix this, do slot++ in all cases. For SSO mode, we overwrite slot for every varying, so this increment only matters on the last varying. Because we process varyings in order, this will set slot to 1 more than the highest assigned slot. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jordan Justen <[email protected]>

* nir/i965: use two slots from inputs_read for dvec3/dvec4 vertex input attributesJuan A. Suarez Romero2017-01-096-29/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, input_reads was a bitmap tracking which vertex input locations were being used. In OpenGL, an attribute bigger than a vec4 (like a dvec3 or dvec4) consumes just one location, any other small attribute. So we mark the proper bit in inputs_read, and also the same bit in double_inputs_read if the attribute is a dvec3/dvec4. But in Vulkan, this is slightly different: a dvec3/dvec4 attribute consumes two locations, not just one. And hence two bits would be marked in inputs_read for the same vertex input attribute. To avoid handling two different situations in NIR, we just choose the latest one: in OpenGL, when creating NIR from GLSL/IR, any dvec3/dvec4 vertex input attribute is marked with two bits in the inputs_read bitmap (and also in the double_inputs_read), and following attributes are adjusted accordingly. As example, if in our GLSL/IR shader we have three attributes: layout(location = 0) vec3 attr0; layout(location = 1) dvec4 attr1; layout(location = 2) dvec3 attr2; then in our NIR shader we put attr0 in location 0, attr1 in locations 1 and 2, and attr2 in location 3 and 4. Checking carefully, basically we are using slots rather than locations in NIR. When emitting the vertices, we do a inverse map to know the corresponding location for each slot. v2 (Jason): - use two slots from inputs_read for dvec3/dvec4 NIR from GLSL/IR. v3 (Jason): - Fix commit log error. - Use ladder ifs and fix braces. - elements_double is divisible by 2, don't need DIV_ROUND_UP(). - Use if ladder instead of a switch. - Add comment about hardware restriction in 64bit vertex attributes.

* i965: Rework gl_TessLevel*[] handling to use NIR compact arrays.Kenneth Graunke2017-01-0610-364/+92
| | | | | | | | | | | | | | | | | | | | | | | | Treating everything as scalar arrays allows us to drop a bunch of special case input/output munging all throughout the backend. Instead, we just need to remap the TessLevel components to the appropriate patch URB header locations in remap_patch_urb_offsets(). We also switch to treating the TES input versions of these as ordinary shader inputs rather than system values, as remap_patch_urb_offsets() just makes everything work out without special handling. This regresses one Piglit test: arb_tessellation_shader-large-uniforms/GL_TESS_CONTROL_SHADER-array-at-limit The compiler starts promoting the constant arrays assigned to gl_TessLevel* to uniform arrays. Since the shader also has a uniform array that uses the maximum number of uniform components, this puts it over the uniform component limit enforced by the linker. This is arguably a bug in the constant array promotion code (it should avoid pushing us over limits), but is unlikely to penalize any real application.
