Will using -fPIC affect the performance in anyway ? Does it disable any optimazations ?
If you had read 'info gcc' you'd have seen this is target dependent.
Typically, it may introduce additional overhead on function calls,
compared with non-relocatable code. On targets where this is an issue,
certain libraries (e.g. libm) might be static linked to avoid the
overhead, which used to approach 5% on ia64.
