DXIL Inline raytracing does not work with bindless tlases.

[DBouma]

When compiled to DXIL, using TraceRayInline() in a pixel shader while having a bindless array of tlases, seems to never hit any geometry.

• When the tlas is bound using a root srv instead, the inline traces seem to work as intended.
• Creating the exact same bindless setup but doing it in a CS instead of a PS, then the inline rays do hit geometry.

This problem does not occur in a PS when the exact same shaders are compiled to spirv.

RaytracingAccelerationStructure tlases[] : register(t0, space0);

struct Constants {
    uint tlas_index;
};

ConstantBuffer<Constants> g_constants: register(b0, space0);

float4 PSMain(float4 input : SV_POSITION) : SV_TARGET
{
    float3 wpos = float3(input.xy + 0.5f, -1);
    
    RayDesc ray;
    ray.Origin = wpos;
    ray.TMin = 0.1;
    ray.TMax = 1000.0;
    ray.Direction = float3(0,0,1);
    
	float3 res = 0.0f;
    
    RayQuery<RAY_FLAG_ACCEPT_FIRST_HIT_AND_END_SEARCH | RAY_FLAG_FORCE_OPAQUE> q;
    q.TraceRayInline(tlases[g_constants.tlas_index], 0, 0xff, ray);
    q.Proceed();

    if (q.CommittedStatus() == COMMITTED_TRIANGLE_HIT) {
        res = float3(1,0,0);
    } else {
        res = float3(0,1,0);
    }
    
	return float4(res,1.0f);
}
