From: Fangrui Song Date: Fri, 20 Jul 2018 11:24:55 +0000 (+0000) Subject: Use default visibility to work around clang -fvisibility-inlines-hidden bug X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2143168e072391eb097a9382ab8ad2ca70ce1d11;p=gcc.git Use default visibility to work around clang -fvisibility-inlines-hidden bug Clang (including trunk and many older versions) incorrectly marks static local variables (__tag) hidden when -fvisibility-inlines-hidden is used. This can lead to multiple instances of __tag when shares objects are used. 2018-07-20 Fangrui Song * include/bits/shared_ptr_base.h (_Sp_make_shared_tag::_S_ti): Use _GLIBCXX_VISIBILITY(default).
