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) \
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;
Is it correct ?
Thanks in advance,
