[cfe-users] Get Source Location details from IR code (Function Pass)

Do we have to initially attach some metadata to the Value? Because in
function pass, when I do F.getAllMetadata(MDs), i do not see any metadata
appending to MDS.
F.hasMetadata() also returns false. What would be the way to get debugLoc
in these scenario?

Thanks and Regards.
