Re: [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. On Mon, Jan 11, 2021 a
