| | | | | | | | | | | | Float suffixes are allowed in all subsequent GLSL specifications, and it's obvious what the user meant if they specify one. Accept it with a warning to avoid breaking applications, like Planeshift (although it looks like between 0.6.1 and 0.6.3 they might have removed the suffixes from their shaders).

* glsl: add forgotten textureOffset function for sampler2DArrayShadowRoland Scheidegger2016-04-211-0/+7
| | | | | | | | | | | | | | | | | | This was part of EXT_gpu_shader4 - as such it should have been supported by glsl 130. It was however forgotten, and not added until glsl 430 - with the wrong syntax no less (glsl 430 mentions it was overlooked). glsl 440 (but revision 8 only) fixed this finally for good. At least nvidia supports this with just version glsl version 1.30 as well (the spec doesn't explicitly say it should be supported retroactively), so just add this to the other glsl 130 textureOffset functions. Passes a (hacked) piglit tex-miplevel-selection test (2DArrayShadow textureOffset -auto) with llvmpipe. v2: fix up comment (by Ian), add testing to commit message.

* glsl: Don't copy propagate or tree graft precise values.Kenneth Graunke2016-04-123-1/+8
| | | | | | | | | | | | | | | | | | | | | | | This is kind of a hack. We currently track precise requirements by decorating ir_variables. Propagating or grafting the RHS of an assignment to a precise value into some other expression tree can lose those decorations. In the long run, it might be better to replace these ir_variable decorations with an "exact" decoration on ir_expression nodes, similar to what NIR does. In the short run, this is probably good enough. It preserves enough information for glsl_to_nir to generate "exact" decorations, and NIR will then handle optimizing these expressions reasonably. Fixes ES31-CTS.gpu_shader5.precise_qualifier. v2: Drop invariant handling, as it shouldn't be necessary (caught by Jason Ekstrand).

| | | | | | | | | | | | | | | | | Consider the case of linking a program with both a vertex and fragment shader. The VS may compute output varyings that are intended for transform feedback, and not read by the fragment shader. In this case, var->data.is_unmatched_generic_inout will be true, but we still cannot eliminate the varyings. We need to also check !var->data.is_xfb_only.

| | | | | | | | | | | | | | | | | | | lower_variable_index_to_cond_assign() did not handle system values. gl_SampleMaskIn[] is a system value, and also an array. Accessing it with a variable index would trigger an unreachable() assert. Rather than adding a new EmitNoIndirectSystemValues flag, we simply lower unconditionally. There is exactly one case where this occurs, and for all current drivers, lowering produces optimal code. Even for future drivers with 32x MSAA, it produces reasonable code.

From the ARB_program_interface_query specification: "* PROGRAM_INPUT corresponds to the set of active input variables used by the first shader stage of <program>. If <program> includes multiple shader stages, input variables from any shader stage other than the first will not be enumerated. * PROGRAM_OUTPUT corresponds to the set of active output variables (section 2.14.11) used by the last shader stage of <program>. If <program> includes multiple shader stages, output variables from any shader stage other than the last will not be enumerated." Previously, we used build_stageref here, which walks over all linked shaders in the program. This meant that internal varyings would be visible. We don't actually need any of build_stageref's code: we already explicitly skip packed varyings, handle modes, and the name comparisons just do a fuzzy string comparison of name with itself.
