Subject: [RFC] libstdc++: Make --enable-libstdcxx-backtrace=auto default to yes
Date: Wed, 23 Aug 2023 17:02:05 +0100 [thread overview]
Message-ID: <20230823160322.237140-1-jwakely@redhat.com> (raw)
Any objections to this? It's a C++23 feture, so should be enabled by
default.
-- >8 --
This causes libstdc++_libbacktrace.a to be built by default. This might
fail on some targets, in which case we can make the 'auto' choice expand
to either 'yes' or 'no' depending on the target.
libstdc++-v3/ChangeLog:
* acinclude.m4 (GLIBCXX_ENABLE_BACKTRACE): Default to yes.
* configure: Regenerate.
