------- Additional Comments From pinskia at gcc dot gnu dot org 2004-11-23 17:09 ------- I really doubt that his change did anything except maybe change the tree level. Here is one which can most likely reproduced before his change: int main (int i) { int lsm_tmp1; int D1127; lsm_tmp1 = i; L9:; switch (lsm_tmp1) { case 0 ... 1: goto L10; case 2 ... 3: goto L3; case 5: goto L5; default : goto L9; } L3:; i = lsm_tmp1; D1127 = 0; goto L7; L5:; lsm_tmp1 = 4; goto L9; L10:; i = lsm_tmp1; D1127 = 1; L7:; return D1127; }
