Invalid warning when using Sampler2D, generating GLSL code

[Ollhax]

I'm trying to compile slang to GLSL via the commandline and I'm getting a warning that I can't make sense of:

1>shaders.slang(40): warning 41012: entry point 'fragmentMain' uses additional capabilities that are not part of the specified profile 'glsl_450'. The profile setting is automatically updated to include these capabilities: 'GL_EXT_texture_query_lod + GL_ARB_sparse_texture_clamp'
1>float4 fragmentMain(CoarseVertex coarseVertex : CoarseVertex) : SV_Target
1>       ^~~~~~~~~~~~

Command line arguments:

SlangC\slangc.exe shaders.slang -profile glsl_450 -target glsl -o $(ProjectDir)shaders.frag -entry fragmentMain

shaders.slang:

Sampler2D sampler;

struct AssembledVertex
{
    float3	position : POSITION;
    float3	color    : COLOR;
    float2	uv       : UV;
};

struct CoarseVertex
{
    float3 color;
    float2 uv;
};

struct VertexStageOutput
{
    CoarseVertex    coarseVertex    : CoarseVertex;
    float4          sv_position     : SV_Position;
};

[shader("vertex")]
VertexStageOutput vertexMain(
    AssembledVertex assembledVertex)
{
    VertexStageOutput output;

    float3 position = assembledVertex.position;
    float3 color    = assembledVertex.color;
    float2 uv       = assembledVertex.uv;

    output.coarseVertex.color = color;
    output.coarseVertex.uv = uv;
    output.sv_position = float4(position, 1.0);

    return output;
}

[shader("fragment")]
float4 fragmentMain(CoarseVertex coarseVertex : CoarseVertex) : SV_Target
{
    return sampler.Sample(coarseVertex.uv);
}

The generated shaders.frag:

#version 450
layout(row_major) uniform;
layout(row_major) buffer;

#line 1 0
layout(binding = 0)
uniform sampler2D sampler_0;


#line 4368 1
layout(location = 0)
out vec4 entryPointParam_fragmentMain_0;


#line 4368
layout(location = 1)
in vec2 coarseVertex_uv_0;


#line 40 0
void main()
{

#line 40
    entryPointParam_fragmentMain_0 = (texture((sampler_0), (coarseVertex_uv_0)));

#line 40
    return;
}

Both my GLSL and slang is a bit rusty, but it looks basic to me. Why would I need the extensions GL_EXT_texture_query_lod and GL_ARB_sparse_texture_clamp here?

To get rid of the warning, remove -profile glsl_450 in your commandline to slangc. If you specified a profile, slang will try to verify you don't use anything not covered by glsl_450 profile. And it seems that the capability definition for texture.Sample method isn't correct.

This is already fixed in tot. No more warnings for the Sample call when specifying glsl_450 profile. Closing.
