--- Comment #7 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #1) > Confirmed, --with-pic being documented would be very nice even though it is > a generic libtool > configure option, it is most used with libstdc++ as shown by the bug reports > about the using static > libstdc++ in a shared library. Note that documenting it has the risk of leading people to think that --with-pic (or --without-pic) is ok to use even in situations when it's not; e.g. x86_64 must always be PIC. If the flag is going to be documented, any such restrictions should be documented as well.
