That sounds absurd as it would totally defeat the purpose of PIC.

It's position independent code exactly _because_ you can't know the
position at link time.

Which is why the compiler would always block a register for house
keeping, when compiling -fPIC (at least it used to be that way). This
hurts more on x86 than on other platforms because x86 is basically a
stack machine with an unclean design (pun intended), but we wouldn't care.
