* glsl: Make #pragma STDGL invariant(all) only modify outputs.Kenneth Graunke2017-11-081-24/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the GLSL ES 3.20, GLSL 4.50, and GLSL 1.20 specs: "To force all output variables to be invariant, use the pragma #pragma STDGL invariant(all) before all declarations in a shader." Notably, this is only supposed to affect output variables. Furthermore, "Only variables output from a shader can be candidates for invariance." It looks like this has been wrong since we first supported the pragma in 2011 (commit 86b4398cd158024f6be9fa830554a11c2a7ebe0c). Fixes dEQP-GLES2.functional.shaders.preprocessor.pragmas.pragma_fragment. v2: Now that all cases are identical (other than compute shaders, which have no output variables anyway), we can drop the switch statement entirely. We also don't need the current_function == NULL check; this was a hold over from when we had a single var_mode_out for both function parameters and shader varyings, in the bad old days.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 259fc505454ea6a67aeacf6cdebf1398d9947759 added linker error for mismatching uniform precision, as required by GLES 3.0 specification and conformance test-suite. Several Android applications, including Forge of Empires, have shaders which violate this rule, on a dead varying that will be eliminated. The problem affects a big number of applications using Cocos2D engine and other GLES implementations accept this, this poses a serious application compatibility issue. Starting from GLSL ES 3.0, declarations with conflicting precision qualifiers are explicitly prohibited. However GLSL ES 1.00 does not clearly specify the behavior, except that "Uniforms are defined to behave as if they are using the same storage in the vertex and fragment processors and may be implemented this way. If uniforms are used in both the vertex and fragment shaders, developers should be warned if the precisions are different. Conversion of precision should never be implicit." The word "used" is not clear in this context and might refer to 1) declared (same as GLES 3.x) 2) referred after post-processing, or 3) linked after all optimizations are done. Looking at existing applications, 2) or 3) seems to be widely adopted. To avoid compatibility issues, turn the error into a warning if GLSL ES version is lower than 3.0 and the data is dead in at least one of the shaders.

| | | | | | | | | | | | | The dynamic index of a vector (not array!) is lowered to a sequence of conditional assignments. However, the interpolate_at_* expressions require that the interpolant is an l-value of a shader input.

Component selection operators (e.g., .xy) may be used when specifying interpolant." For members of interface blocks, var->data.must_be_shader_input must be determined on-the-fly after lowering interface blocks, since we don't want to disable varying packing for an entire block just because one input in it is used in interpolateAt*. v2: keep setting must_be_shader_input in ast_function (Ian) v3: follow the relaxed rule of GLSL 4.60 v4: only apply the relaxed rules to desktop GL (the ES WG decided that the relaxed rules may apply in a future version but not retroactively; see also dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_centroid.negative.*) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101378 Reviewed-by: Ian Romanick <[email protected]> (v1) Reviewed-by: Timothy Arceri <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | Some symbols gathered in the symbols table during parsing are needed later for the compile and link stages, so they are moved along the process. Currently, only functions and non-temporary variables are copied between symbol tables. However, the built-in gl_PerVertex interface blocks are also needed during the linking stage (the last step), to match re-declared blocks of inter-stage shaders. This patch adds a new utility function that will factorize current code that copies functions and variables between two symbol tables, and in addition will copy explicitly declared gl_PerVertex blocks too. The function will be used in a subsequent patch. v2 (Neil Roberts): Allow the src symbol table to be NULL and explicitly copy the gl_PerVertex symbols in case they are not referenced in the exec_list.

* glsl/linker: validate explicit locations for SSO programsIago Toral Quiroga2017-10-263-0/+71
| | | | | | | | | | | v2: - we only need to validate inputs to the first stage and outputs from the last stage, everything else has already been validated during cross_validate_outputs_to_inputs (Timothy). - Use MAX_VARYING instead of MAX_VARYINGS_INCL_PATCH (Illia) Reviewed-by: Timothy Arceri <[email protected]> Reviewed-by: Ilia Mirkin <[email protected]>
* glsl/linker: generalize validate_explicit_variable_location for SSOIago Toral Quiroga2017-10-261-2/+16
| | | | | | | | | | | | | | | | | | | For non-SSO programs, we only need to validate outputs, since the cross validation of outputs to inputs will ensure that we produce linker errors for invalid inputs too. Hoever, for the SSO path there is no output to input validation, so we need to validate inputs explicitly. Generalize the function so it can handle this as well. Also, notice that vertex shader inputs and fragment shader outputs are already validated in assign_attribute_or_color_locations() for both SSO and non-SSO paths, so we should not try to validate that here again (in fact, the function would require explicit paths to handle these two cases properly).

* glsl/linker: create a helper function to validate explicit locationsIago Toral Quiroga2017-10-261-39/+55
| | | | | | | | | Currently, we only validate explicit locations for non-SSO programs. This creates a helper that we can call from both SSO and non-SSO paths directly, so we can reuse all the logic behind this.
