------- Comment #5 from rguenth at gcc dot gnu dot org 2008-12-02 13:23 ------- This is const_binop folding -1 >> -130 to zero and fold_binary -1 >> n to -1.
11458 case RSHIFT_EXPR: 11459 /* Optimize -1 >> x for arithmetic right shifts. */ 11460 if (integer_all_onesp (arg0) && !TYPE_UNSIGNED (type)) 11461 return omit_one_operand (type, arg0, arg1); 11462 /* ... fall through ... */ but this is of course only correct if arg1 is >= 0. I have a patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38359 ------- You are receiving this mail because: ------- You reported the bug, or are watching the reporter. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
