This patch uses the libc_ifunc macro to create already existing ifunc functions time and gettimeofday on intel. This way, the libc_hidden_def macro can be used instead of the libc_ifunc_hidden_def one which was only used here. Thus the macro is removed from libc-symbols.h. On i386, the __GI_* symbols do not target the ifunc symbol and thus the redirection construct has to be applied here.
I'm not sure if I understand what is going on here. sysdeps/unix/sysv/linux/x86/gettimeofday.c is compiled straight for x86_64, but wrapped on i386, right?
I wonder if it possible to avoid some of the preprocessor magic by introducing a separate x86_64 file.
Thanks, Florian
