Or are there any negative effects by enabling -fPIC?
-fPIC generates slower code. I am not aware of up-to-date data on how much slower.
However, note that both my library of code and ATLAS are primarily interested in floating point computation performance. Different conclusions may be reached for other types of computation load though I very much doubt it.
That's because the x64 fPIC is much more sane than the x86 fPIC, see for your self: http://www.bailopan.net/blog/?p=50. One additional move, thats all. Cheers, Anteru
