* nir: Flip gl_SamplePosition in nir_lower_wpos_ytransform().Francisco Jerez2016-11-031-0/+24
| | | | | | | | | | | | | | | | | | Assuming the hardware is set up to use a screen coordinate system flipped vertically with respect to the GL's window coordinate system, the SYSTEM_VALUE_SAMPLE_POS vector will also be flipped vertically with respect to the value expected by the GL, so we need to give it the same treatment as gl_FragCoord. Fixes the following CTS tests on i965: ES31-CTS.functional.shaders.multisample_interpolation.interpolate_at_offset.at_sample_position.default_framebuffer ES31-CTS.functional.shaders.sample_variables.sample_pos.correctness.default_framebuffer when run with any multisample configuration, e.g. rgba8888d24s8ms4.

* glsl: fix lowering of UBO references of named blocksNicolai Hähnle2016-11-031-5/+5
| | | | | | | | | | | | | | When a UBO reference has the form block_name.foo where block_name refers to a block where the first member has a non-zero offset, the base offset was incorrectly added to the reference. Fixes an assertion triggered in debug builds by GL45-CTS.enhanced_layouts.uniform_block_layout_qualifier_conflict.

* glsl: Update deref types when resizing implicitly sized arrays.Kenneth Graunke2016-11-031-23/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At link time, we resolve the size of implicitly sized arrays. When doing so, we update the type of the ir_variables. However, we neglected to update the type of ir_dereference nodes which reference those variables. It turns out array_resize_visitor (for GS/TCS/TES interface array handling) already did 2/3 of the cases for this, so we can simply refactor the code and reuse it. This fixes: GL45-CTS.shader_storage_buffer_object.basic-syntax GL45-CTS.shader_storage_buffer_object.basic-syntaxSSO which have an SSBO containing an implicitly sized array, followed by some other members. setup_buffer_access uses the dereference types to compute offsets to fields, and it had a stale type where the implicitly sized array's length was still 0 instead of the actual length. While we're here, we can also fix update_array_sizes to properly update deref types as well, fixing a FINISHME from 2010.

* mesa/glsl: delete previously linked shaders earlier when linkingTimothy Arceri2016-11-034-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the delete linked shaders call to _mesa_clear_shader_program_data() which makes sure we delete them before returning due to any validation problems. It also reduces some code duplication. From the OpenGL 4.5 Core spec: "If LinkProgram failed, any information about a previous link of that program object is lost. Thus, a failed link does not restore the old state of program. ... If one of these commands is called with a program for which LinkProgram failed, no error is generated unless otherwise noted. Implementations may return information on variables and interface blocks that would have been active had the program been linked successfully. In cases where the link failed because the program required too many resources, these commands may help applications determine why limits were exceeded." Therefore it's expected that we shouldn't be able to query the program that failed to link and retrieve information about a previously successful link. Before this change the linker was doing validation before freeing the previously linked shaders and therefore could exit on failure before they were freed. This change also fixes an issue in compat profile where a program with no shaders attached is expect to fall back to fixed function but was instead trying to relink IR from a previous link.

* glsl: Improve accuracy of alpha scaling in advanced blend lowering.Kenneth Graunke2016-10-281-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When blending with GL_COLORBURN_KHR and these colors: dst = <0.372549027, 0.372549027, 0.372549027, 0.372549027> src = <0.09375, 0.046875, 0.0, 0.375> the normalized dst value became 0.99999994 (due to precision problems in the floating point divide of rgb by alpha). This caused the color burn equation to fail the dst >= 1.0 comparison. The blue channel would then fall through to the dst < 1.0 && src >= 0 comparison, which was true, since src.b == 0. This produced a factor of 0.0 instead of 1.0. This is an inherent numerical instability in the color burn and dodge equations - depending on the precision of alpha scaling, the value can be either 0.0 or 1.0. Technically, GLSL floating point division doesn't even guarantee that 0.372549027 / 0.372549027 = 1.0. So arguably, the CTS should allow either value. I've filed a bug at Khronos for further discussion (linked below). In the meantime, this patch improves the precision of alpha scaling by replacing the division with (rgb == alpha ? 1.0 : rgb / alpha). We may not need this long term, but for now, it fixes the following CTS tests: ES31-CTS.blend_equation_advanced.blend_specific.GL_COLORBURN_KHR ES31-CTS.blend_equation_advanced.blend_all.GL_COLORBURN_KHR_all_qualifier Cc: [email protected] Cc: [email protected] Bugzilla: https://cvs.khronos.org/bugzilla/show_bug.cgi?id=16042 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eduardo Lima Mitev <[email protected]> Reviewed-by: Francisco Jerez <[email protected]>

* glsl: Size TCS->TES unsized arrays to gl_MaxPatchVertices for queries.Kenneth Graunke2016-10-274-3/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SSO validation and other program interface queries want to see that unsized (non-patch) TCS output/TES input arrays are implicitly sized to gl_MaxPatchVertices. By the time we create the program resource lists, we've sized the arrays to their actual size. (We try to create TCS output arrays to match the output patch size right away, and at this point, we should have shrunk TES input arrays.) One option would be to keep them sized to gl_MaxPatchVertices, and defer shrinking them. But that's a big change, and I don't think it's a good idea. Instead, this patch introduces a new ir_variable flag which indicates the variable is implicitly to gl_MaxPatchVertices. Then, the linker munges the types when creating the resource list, ignoring the size in the IR's types. Basically, lie about it for resource queries. It's ugly, but I think it ought to work. We probably could use var->data.implicit_sized_array for this, but I opted for a separate bit to try and avoid convoluting the existing SSBO handling. They're similar in concept, but share none of the same code...
