            Bug ID: 43030
           Summary: llvm-objdump does not work for BPF in some reasonably
                    common cases
           Product: new-bugs
           Version: 9.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: new bugs

Commit https://reviews.llvm.org/D57939 ("[DWARF] Refactor
RelocVisitor and fix computation of SHT_RELA-typed relocation entries)
made a change for relocation resolution when operating 
on an object file.

The change unfortunately broke BPF as given SymbolValue (S) and
Addent (A), previously relocation is resolved to
        S + A
and after the change, it is resolved to
        S

This bug will happen if there are two bpf programs
defined in the same file, which is fairly common.

The bug is fixed in trunk (currently 10.0.0):
   https://reviews.llvm.org/rL369199

This is to request backport the fix to release 9.0.0.
