This call and pop is old-style PIC and not good for new cpus because it breaks the call-stack. Please use the new style that calls a function (fpc_geteipasebx). This also generated by the compiler. See i386/cgcpu.pas and search for g_maybe_got_init.
I recently read that on the more recent processors, call/pop is slightly faster again (I suppose they detect a call to next instruction and don't add it to the internal call stack or so).
