Zack Weinberg <zackw at panix dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |zackw at panix dot com --- Comment #26 from Zack Weinberg <zackw at panix dot com> --- /subscribe I've tripped over this problem myself in the context of the new password-hashing library, libxcrypt (see https://github.com/besser82/libxcrypt/issues/24 ) Our symbol-versioning techniques are lifted from glibc (see https://github.com/besser82/libxcrypt/blob/aae4c1baea534d2e4c9dfe2faf42ee0c5f7a6f22/crypt-port.h#L122 ). Function attributes seem like a good replacement to me, although I'd ask that people think about how a library author might write macros that will seamlessly fall back to the older technique.
