--- Comment #10 from H.J. Lu <hjl.tools at gmail dot com> --- (In reply to Sam James from comment #9) > Do we want to implement an auto mode later? > > r16-3355-g96a291c4 doesn't change the default, but allows distributions to > do it easily. We could check whether ld emits GLIBC_ABI_GNU_TLS or > GLIBC_ABI_GNU2_TLS to decide the default. Do we need to check both glibc and ld for GLIBC_ABI_GNU_TLS/GLIBC_ABI_GNU2_TLS support? > Then per richi's comment > (https://inbox.sourceware.org/gcc/CAFiYyc3heLVt1yhP3D8bNqSdhfR6t3- > jq4izxf5varcqbdv...@mail.gmail.com/) if I understand it right, it's on > integrators to change it back if they need to for other compatibility > reasons. > > I don't know if by "change the default" he meant "change it back if they > need to" or "change it at all". I hope he meant the former.
