What are they're supposed to do and > what are they needed for? They are the core of the C99 exp2l and log2l functions, resp. Nobody has yet written generic implementations of them for 80-bit extended float. Currently only x86, m68k and x86-64 specific versions exist, and a 128-bit extended float version of log2l. Search for e_exp2l.* and e_log2l.* in the sysdeps hierarchy for the existing implementations. > I'm asking since on ia64 "make check" keeps failing with: > > __ieee754_exp2l not implemented > __ieee754_log2l not implemented It's not failing because of this. When a math funtion is not implemented it is just skipped by the tests. Actually, all math tests are working fine here.
