Since

/* Clear all scratch integer registers.  */
#define clear_int_hardware_registers \
  asm __volatile__ ("xor %%eax, %%eax\n\t" \
                    "xor %%edx, %%edx\n\t" \
                    "xor %%ecx, %%ecx\n\t" \
                    ::: "eax", "edx", "ecx");

/* Clear both hardware and register structs for integers, excluding the
   one used to return aggregate.  */
#define clear_non_sret_int_registers \
  clear_struct_registers \
  clear_non_sret_int_hardware_registers

#undef D
#define D(I) { static struct S_ ## I s; current_test = I; struct_addr =
(void*)&s; \
  clear_non_sret_int_registers; \
  s = WRAP_RET(f_ ## I) (); \
  check_all(class_ ## I, sizeof(s)); \
}

trash PIC register, iamcu tests should add -fno-PIC -no-pie.
