--- Comment #17 from howarth at bromo dot med.uc.edu ---
The only other place that looks promising is...
case UNSPEC_GOTOFF:
/* Refuse GOTOFF in 64bit mode since it is always 64bit when used.
While ABI specify also 32bit relocation but we don't produce it in
small PIC model at all. */
if ((GET_CODE (XVECEXP (disp, 0, 0)) == SYMBOL_REF
|| GET_CODE (XVECEXP (disp, 0, 0)) == LABEL_REF)
&& !TARGET_64BIT)
return !TARGET_PECOFF && gotoff_operand (XVECEXP (disp, 0, 0), Pmode);
return false;
in gcc/config/i386/i386.c. As I understand the problem, we need to expand the
existing code to treat -mcmodel=small in the current manner but
-mcmodel=medium/large needs to switch to GOT.
