2024-02-05Add glsl implementation of Texture.InterlockedAddF32 (#3550)Yong He
2024-02-05Implement GLSL build-in functions related to texture (#3544)Jay Kwak
* Implement GLSL texture related built-in functions Partially resolves #3362 This change implemented GLSL build-in functions described in the following sections of "OpenGL Spec" document. 8.9.1. Texture Query Functions 8.9.2. Texel Lookup Functions 8.9.4. Texture Gather Functions 8.9.5. Compatibility Profile Texture Functions About 200 functions are newly implemented. Most of the functions are calling the HLSL implementation so they are expected to work for all targets but they haven't been tested throughly yet. __TextureImpl got a new generic parameter, "isRectangle", to support sampler2DRect and sampler2DRectShadow. It is a sampler for rectangular texture with no mipmaps. For the reason, its "GetDimentions()" doesn't return mip information. The sampling needs to happen in an integer coordinate not in a normalized [0,1] range. but this hasn't been implemenented yet. Texture functions whose name include "Offset" takes an integer type parameter and those values are required to be a compile-time constant. However, our currentl implementation of slangc seems to make the values not-compile-time constant. As a workaround, the test case uses __LINE__ macro to use a unique numbers so that slangc wouldn't collect them into a runtime variable. I put "constexpr" on "offset" parameters as much as possible. But the issue was still reproduced when targetting SPIRV. Texture functions whose name include "Proj" are emulated by dividing the coordinate value with its last component. For that reason, they take one additional component for its coordinate value. As an example, following function takes two components for sampler1D, instead of one: vec4 textureProj(sampler1D sampler, vec2 p); All shadow samplers stores depth-compare-value at the last component. But sampler1DShadow take one extra component, which is vec3 not vec2. It is unclear what the reason is but the second component is unused in this case. Here is an example, float texture(sampler1DShadow sampler, vec3 p); samplerCubeArrayShadow takes five components for its coordinate and the depth-compare-value cannot be stored in the last component of the cooridnate. It is separated out as an independent parameter, float texture(samplerCubeArrayShadow sampler, vec4 p, float compare); TextureGather functions got some modifications. The existing implementation was calling textureGatherOffset[s] with the parameters in a wrong order. This mistake is corrected. * Bring back GatherCmpRed/Green/Blue/Alpha HLSL has GatherCmpRed/Green/Blue/Alpha functions and it was removed from my previous change by a mistake. This change brings them back. * Disabling two failing tests in intrinsic-texture The new test file, intrinsic-texture.slang, has five test settings and two of them are currently failing; they are targetting HLSL and CPP. This change disables them to avoid confusion. * Remove "isRectangle" parameter from __TextureInfo Partially resolves #3362 This commit has a few changes based on the feedback from the code reviews. 1. Remove "isRectangle" parameter from __TextureInfo, because "sampler2DRect" can be replaced with "sampler2D" that always uses lod level 0. All functions associated to "Rect" are also removed. 2. Enabled tests for "samplerBuffer". 3. Removed "__target_intrinsic(glsl)" from glsl.meta.slang, because we want to stay away from it in the future. 4. Some tests in intrinsic-texture.slang are disabled if the functions take constant offset values or take MultiSample samplers. --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-01-23Fix incorrect behavior of operator% (#3470)Jay Kwak
* Fix incorrect behavior of operator% Fixes #1059. This change fixes the incorrect translation of "operator%" from HLSL to SPIRV. The issue stems from the fact that the behavior of "operator%" in GLSL differs from that in HLSL. In HLSL it behaves as "remainder" where as it behaves as "modulus" in GLSL. We have been using SpvOpFMod for operator% when Slang compiles from HLSL to SPRIV, which is incorrect. This change switches it to SpvOpFRem. The tests are slightly modified to reveal any potential issues. * Change output type of test/compute/frem For testing the operator%, we are using "int" as the output type of the test, "test/compute/frem.slang". Since the operands are in float type, it is more preferable to have a float type as the resulting type. This can be done with an option, "-output-using-type". --------- Co-authored-by: Yong He <yonghe@outlook.com>
