To get this result:
```
PrimFunc([placeholder, placeholder, placeholder, T_cast])

"tvmgen_default_fused_nn_conv2d_add_fixed_point_multiply_clip_cast_cast_21",
"tir.noalias": (bool)1} {
allocate DepthwiseConv2d[int32 * 1], storage_scope = global
for (ax0.ax1.fused.ax2.fused.ax3.fused, 0, 401408) {
DepthwiseConv2d[0] = 0
for (di, 0, 3) {
for (dj, 0, 3) {
DepthwiseConv2d[0] = (DepthwiseConv2d[0] +
(int32(tir.if_then_else(((((1 <= (floordiv(ax0.ax1.fused.ax2.fused.ax3.fused,
7168) + di)) && ((floordiv(ax0.ax1.fused.ax2.fused.ax3.fused, 7168) + di) <

ax0.ax1.fused.ax2.fused.ax3.fused) - 7296)],
(int16)0))*int32(placeholder[(((di*384) + (dj*128)) +

}
