Problem Description A regression from CTS test is found when textureQueryLod is used. The tests pass but they print a validation error.
textureQueryLod
Goal We should use the function with a capability, "ImageQuery", before using the instruction, OpImageQueryLod.
OpImageQueryLod
Repro step The following vertex shader code is from CTS test, "dEQP-VK.glsl.texture_functions.query.texturequerylod.isampler2d_fragment".
//TEST:SIMPLE:-target spirv-asm -entry main -stage fragment #version 450 core layout(location = 0) out mediump vec4 o_color; layout (location = 0) in highp vec2 v_texCoord; layout(set = 0, binding = 0) uniform highp isampler2D u_sampler; void main() { o_color = vec4(textureQueryLod(u_sampler, v_texCoord), 0.0, 1.0); }
When ran, a validation error is observed as following,
error: line 40: Opcode ImageQueryLod requires one of these capabilities: ImageQuery %20 = OpImageQueryLod %v2float %16 %19
