I have defined the macro TC_CGEN_PARSE_FIX_EXP and am using it to
to check if a fixup was created like this :

#define TC_CGEN_PARSE_FIX_EXP(opinfo, exp) \
  brc_cgen_parse_fix_exp(opinfo, exp)
extern int brc_cgen_parse_fix_exp (int, expressionS *);

brc_cgen_parse_fix_exp (int opinfo, expressionS * exp)
  if (exp->X_op != O_illegal && exp->X_op != O_absent
      && exp->X_op != O_constant && exp->X_op != O_register)
    fixup_created = 1;

  return opinfo;

Is it correct ?

Thanks in advance,
