I need to stack the top half of two images(hls::Mat) together. I ended up having the following errors.

WARNING: Hls::stream 'hls::stream.8' contains leftover data, which may result in RTL simulation hanging.

if I flush the leftover by

while (1)
 img_in0 >> p0;
 if (!p0.val[0])
 break;

I got the following error

WARNING: Hls::stream 'hls::stream.7' is read while empty, which may result in RTL simulation hanging.

I wonder what is the best way to flush the leftover?
