| | | | | | | | | | | Add a note to clarify that while Vulkan allows mod(x,y) to be in [0, y] range, OpenGL does not allow it, so the lowering ensures the result is always in [0, y) range, as this lowering is shared by the Vulkan and OpenGL implementation.

* nir: Add optimization for doing removing f16/f32 conversionsHyunjun Ko2020-02-241-0/+7
| | | | | | | | | | | | | | | | | | | This eliminates conversions between f16 and f32 where possible. We can always remove an upcast followed by a down cast, that is: f2f16 ( f2f32 (a) ) -> a f2fmp ( f2f32 (a) ) -> a In the other direction, f2f16 loses precision and can't be undone by a f2f32. However, by definition it's always safe to elminate f2fmp: f2f32 ( f2fmp (a) ) -> a v2.

* nir/opcodes: Add nir_op_f2fmpNeil Roberts2020-02-242-0/+11
| | | | | | | | | | | | | | | This opcode is the same as the f2f16 opcode except that it comes with a promise that it is safe to optimise it out if the result is immediately converted back to a 32-bit float again. Normally this would be a lossy conversion and so it would be visible to the application, but if the conversion is generated as part of the mediump lowering process then this removal doesn’t matter. The opcode is eventually replaced with a regular f2f16 in the late optimisations so the backends don’t need to handle it.

| | | | | | | | | | | | | To facilitate lowering SSBOs to globals, we need a load_ssbo_address intrinsic. This intrinsic takes an SSBO index and loads the address in global memory of the SSBO (likely implemented via a uniform in the driver). In the future, we'll support bounds checking, but at the moment this is not supported (this pass should only be used for trusted contexts at the moment, i.e. contexts without robustness extensions).

Spec updates have not landed yet, but I'll get to it soon. :) The extra hurt shaders on Gen8+ are a handful of shaders that see things like bcsel(fmin(b - a, a - c) >= 0, x, y) converted to bcsel(a >= b && c >= a, x, y) The former can be generated as a CSEL instruction. If either b - a or a - c is used elsewhere in the shader, this saves an instruction. All Haswell+ platforms had similar results.

* r600/sfn: Add lowering UBO access to r600 specific codesGert Wollny2020-02-102-0/+10
| | | | | | | | | | r600 reads vec4 from the UBO, but the offsets in nir are evaluated to the component. If the offsets are not literal then all non-vec4 reads must resolve the component after reading a vec4 component (TODO: figure out whether there is a consistent way to deduct the component that is actually read).

Thanks to imirkin for fixing up the nouveau driver (and a couple of core details). This fixes the computed qualifiers for EXT_shader_image_load_store's non-integer sizeNxM qualifiers, which we don't have tests for.

| | | | | | | | | | | | | | Midgard can't write depth and stencil separately. It has to happen in a single store operation containing both. Let's add a panfrost specific intrinsic and turn all depth/stencil stores into a packed depth+stencil one. Note that this intrinsic is not yet handled in emit_intrinsic(), but we'll address that later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Clang has a warning about overloading virtuals that triggers when a derived class defines a virtual function that's an overload of function in the base class. This kind of thing: struct chart; // let's pretend this exists struct Base { virtual void* get(char* e); }; struct Derived: public Base { virtual void* get(chart* e); // typo, we wanted to override the same function }; The solution is to use using Base::get; to be explicit about the intention to reuse the base class virtual. We hit this a lot with out glsl ir_hierarchical_visitor visitor pattern, so let's adds some 'using' to calm down the compiler.

* nir: Make nir_deref_path_init skip trivial castsCaio Marcelo de Oliveira Filho2020-01-291-14/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a NIR generated using SPIR-V initializers to variables, copy propagation can end up transforming vec1 32 ssa_33 = deref_var &@1 (shared mat2x4) vec1 32 ssa_35 = mov ssa_33 vec1 32 ssa_7 = deref_cast (mat2x4 *)ssa_35 (shared mat2x4) /* ptr_stride=0 */ into vec1 32 ssa_33 = deref_var &@1 (shared mat2x4) vec1 32 ssa_7 = deref_cast (mat2x4 *)ssa_33 (shared mat2x4) /* ptr_stride=0 */ Before the optimization, the "head" of a path of deref that uses ssa_7 will be the cast. After, it will be the variable in ssa_33. Since the types are the same, this is a trivial cast that would be picked up by nir_opt_deref. If we need to compare such deref-chain after optimization with another deref-chain for the same variable, the compare function will get confused by the cast in the middle. One alternative would be to add nir_opt_deref to places that compare derefs, but that might not scale well, so skip the trivial casts when generating the paths instead.
