--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> 2011-03-17 16:56:13 UTC --- Richard, this patch of yours fails on IRIX 5 and 6. I suppose this is a target bug, since it does pass on other platforms (Tru64 UNIX, Solaris 2/SPARC and x86) that don't have mempcpy in libc either. What to do about this? XFAIL (or rather skip since otherwise the `failed to produce executable' warnings remain)? Rainer
