<pre>Commit <a href="https://reviews.llvm.org/D57939">https://reviews.llvm.org/D57939</a> ("[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):
<a href="https://reviews.llvm.org/rL369199">https://reviews.llvm.org/rL369199</a>
This is to request backport the fix to release 9.0.0.</pre>
