Yes, that omission (and that of __unordxf2) is bug 25232.

I would have thought this should inherit from GCC_4.4.0, and this
declaration should be in libgcc-std.ver even if some targets don't have
any 4.5.0 symbols (see e.g. the 4.1.0 version there).

Do you also need __copysigntf3 and __fabstf2 for 32-bit only, such as
GNU/Linux has?
In the course of reviewing the symbol lists I noticed 32-bit GNU/Linux was
apparently accidentally not exporting one symbol, and filed bug 43383 for
that.
