False. You need -fPIC for libraries on ARM, which means that you need it on XScale - and that's an Intel processor...
I looked up the -fPIC option in "Using and Porting GNU CC", version 2.95, where it says on page 110:
"This option makes a difference on the m68k, m88k, and the Sparc."
Well, that manual is a little old, so maybe that information is outdated...
Klaus
the same hint is still included in the manpage of "gcc (GCC) 4.0.2"
-fPIC If supported for the target machine, emit position-independent code, suitable for dynamic linking and avoiding any limit on the size of the global offset table. This option makes a differenceon the m68k, PowerPC and SPARC. Position-independent code requires special support, and therefore works only on certain machines.
i my idea is likewise that it doesn't care on Intel systems.
Nope, you must read "This option makes a difference on the m68k, PowerPC and SPARC." in contrast to -fpic. -fPIC results to same code as -fpic on x86.
