To: libstdc++, gcc-patches
Tested x86_64-linux, pushed to trunk. Worth backporting to gcc-11 too.
The default is -gdwarf-5 now, so this is hurting rather than improving
things.
libstdc++-v3/ChangeLog:
* configure.ac (GLIBCXX_ENABLE_DEBUG_FLAGS): Remove -gdwarf-4
from default flags.
* configure: Regenerate.
