[PATCH] D110422: [AIX] Enable PGO without LTO

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

> we can NOT guarantee that the relocations get resolved to the intended weak symbol, so we can not ensure the correctness of the relative CounterPtr, so we have to use private linkage for counter and data symbols.

In other binary formats the first weak definition is selected and other weak definitions are discarded.
Do you mean that AIX ld doesn't pick the first weak definition?
