DirectX 11 Compute Shader 5 loop - hlsl

Question

I have the following compute shader code for computing depth of field. However, very unusually, the loop executes just once, even if g_rayCount is 10. Please have a look in the main function raycastercs where the for loop lies.

SamplerState SSLinear
{
Filter = Min_Mag_Linear_Mip_Point;
AddressU = Border;
AddressV = Border;
AddressW = Border;
};
float3 CalculateDoF(uint seedIndex, uint2 fragPos)
{
;
}
[numthreads(RAYCASTER_THREAD_BLOCK_SIZE, RAYCASTER_THREAD_BLOCK_SIZE, 1)]
void RaycasterCS(in uint3 threadID: SV_GroupThreadID, in uint3 groupID: SV_GroupID, in uint3 dispatchThreadID :SV_DispatchThreadID)
{
uint2 fragPos = groupID.xy * RAYCASTER_THREAD_BLOCK_SIZE + threadID.xy;
float4 dstColor = g_texFinal[fragPos];
uint seedIndex = dispatchThreadID.x * dispatchThreadID.y;
float3 final = float3(0, 0, 0);
float color = 0;
[loop][allow_uav_condition]
for (int i = 0; i < g_rayCount; ++i);
{
float3 dof = CalculateDoF(seedIndex, fragPos);
final += dof;
}
final *= 1.0f / ((float) g_rayCount);
g_texFinalRW[fragPos] = float4(final, 1);
}

Answer 1

Remove the semicolon at the end of the for statement
for (int i = 0; i < g_rayCount; ++i) // removed semicolon
{
float3 dof = CalculateDoF(seedIndex, fragPos);
final += dof;
}
As I guess you know, the semicolon was just running an empty for loop, then the code in braces was thereafter executed just once.
