Additionally, consecutive (fall-through) case statements7come out messy. This is a peculiarity of the C grammar. The following:8 9 switch (myvar) {10 case 10:11 k = 10;12 p = k + 1;13 return 10;14 case 20:15 case 30:16 return 20;17 default:18 break;19 }20 21Creates this tree (pseudo-dump):22 23 Switch24 ID: myvar25 Compound:26 Case 10:27 k = 1028 p = k + 129 return 1030 Case 20:31 Case 30:32 return 2033 Default:34 break35 36The goal of this transform is to fix this mess, turning it into the37following:38 39 Switch40 ID: myvar41 Compound:42 Case 10:43 k = 1044 p = k + 145 return 1046 Case 20:47 Case 30:48 return 2049 Default:50 break51 52A fixed AST node is returned.
