...’s entry value when we lose track of parameter’s location. As a natural way of handling this problem we used Clang’s Sema and its constness check to embed this information in variable’s declaration which is later used for DILocalVariable construction. For call-site information, new DINode metadata DICallSite and DICallSiteParam are defined and these are emitted by the Clang frontend. The metadata is associated to the call or invoke IR instruction. Here is an example: %call5 = call i32 @fed_em_strncmp(i8* %arraydecay, i8* %arraydecay1, i64 5), !dbg !114, !call_site !101 … !99 = !DICallSiteParam(argno:...

...ly, but it seems like an ideal match for an unmodified formal parameter. Yes, it is the idea.
