            Bug ID: 36276
           Summary: PDB * Linker * module does not contain incremental
                    linking thunks
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: stefan.reinalter at molecular-matters.com

PDBs produced by MSVC's linker contain a * Linker * compiland that stores
incremental linking thunks as SymTagThunk children of this linker compiland,
such as the following (output produced using DIA2Dump):

Thunk          : [00001005][0001:00000005], target [0000A1B0][0001:000091B0] 
Thunk          : [0000100A][0001:0000000A], target [00004720][0001:00003720] 
Thunk          : [0000100F][0001:0000000F], target [0000D800][0001:0000C800] 

PDBs produced by lld contain the * Linker * compiland (with environment and
details), but don't store any thunks.

Is this something that could be added to lld?
