[PATCH] D145208: [COFF] Add MC support for emitting IMAGE_WEAK_EXTERN_ANTI_DEPENDENCY symbols

[Eli Friedman via Phabricator via llvm-commits]

efriedma updated this revision to Diff 513359.
efriedma added a comment.

Update to fix the addrsig crash.

If an alias points to a weak symbol (which is not itself an alias), the alias is referring to the address of the definition, not the symbol itself.  Make sure MCExpr::findAssociatedFragment continues to handle that case correctly.
