Default sampler states in HLSL :(

sampler.hlsl

// HLSL does allow initializing sampler states with a syntax
// like this. However the state settings themselves are nowhere
// to be found in the compiled shader bytecode (as of d3dcompiler_47.dll
// 10.0.14393 from Win10 SDK), and can't be accessed via ID3D11ShaderReflection
// either.
//
// Looks like the compiler only emits the sampler default values if compiling
// the deprecated "effect file" target.
//
// SAD!
SamplerState smp { AddressU = Clamp; AddressV = Wrap; };

Texture2D tx;

float4 frag (float2 uv : TEXCOORD0) : SV_Target
{
    return tx.Sample(smp, uv);
