Hi,
I am working on a C/C++ networking project and I want to find an efficient way to store an IPv6 address. So far, I have thought on int128_t/uint128_t or __int128_t.
I would like to know from which version of gcc are this types suported , for which platforms(especially IA-32/IA-64) and also if there are any known bugs.
Thank you,
Evelina

See https://gcc.gnu.org/gcc-4.6/changes.html
"Support for a new data type __int128 for targets having wide enough
machine-mode support."
I don't know about known bugs, try searching bugzilla.
