libffi-3.3 is mostly compatible with 3.2.x series. There are a few things to watch out: - SONAME changed to .so.7: libffi ebuilds got SLOT=0/7 You might want to add dependency against that to save a @revdep-rebuild iteration. - There was at least one minor API change in x86_64 supported calling convention list. A few packages might break. See: https://wiki.gentoo.org/wiki/Libffi_3.3_porting_notes/FFI_SYSV
We'll gather example fixes at: https://wiki.gentoo.org/wiki/Project:Toolchain#libffi-3.3 Tracker bug: https://bugs.gentoo.org/show_bug.cgi?id=libffi-3.3 Please add newly discovered failures against that bug. I hope to see low amount of failures. All should be easy to fix. If there will be large fallout I'll mask libffi-3.3. -- Sergei
