Hi Kevin,

Although https://bitbucket.org/jimplank/gf-complete does not have explici=
t #if related to AVX http://en.wikipedia.org/wiki/Advanced_Vector_Extensi=
ons , it is used when the compiler supports it ( https://bitbucket.org/ji=
mplank/gf-complete/src/f8ff1e2f64fc88bf74861a0ceec44d130ff1902c/m4/ax_ext=
=2Em4?at=3Dmaster#cl-252 ) and some AVX specific instructions are used in=
 the compiled binary.

http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/i386-and-x86-64-Options.html#=
i386-and-x86-64-Options suggests that AVX is not widely spread.

How important is AVX to gf-complete ? Is it nice to have but with margina=
l benefits ? Or does it make a significant difference ?

Thanks for all the help :-)
