Having two sets of memcpy implementations (especially when we have many memcpy implementations on x86_64 and i?86 selectable via STT_GNU_IFUNC), even if the workaroundish one is placed in compat .text subsections, would waste too much code section in libc.so.6. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
