From 6d8fcee694b9581630a7f27fcbf0009fc44d7baa Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Thu, 25 Mar 2021 11:05:37 +0100 Subject: locale: Use compat_symbol_reference in _nl_postload_ctype These symbol usages are not definitions, so compat_symbol_reference is more appropriate than compat_symbol. compat_symbol_reference is also safe to emit multiple times (in case the inline assembly is duplicated; this is possible because it is nested in a function). compat_symbol does not necessarily have this property because it is intended to provide a symbol definition.
