[committed] libstdc++: Move __glibcxx_assert_fail to its own file
Checks
Commit Message
Tested aarch64-linux. Pushed to trunk.
Maybe worth backporting too.
-- >8 --
This avoids a dependency on the other symbols in src/c++11/debug.o when
linking statically to libstdc++.a without using -Wl,--gc-sections.
libstdc++-v3/ChangeLog:
* src/c++11/Makefile.am: Add new file.
* src/c++11/Makefile.in: Regenerate.
* src/c++11/debug.cc (__glibcxx_assert_fail): Move to ...
* src/c++11/assert_fail.cc: New file.
