<div>Hi all,<br>
<br>
I was inspecting the AST dump of this switch:<br>
<br>
<font face="Courier New">void test_switch(int t) {<br>
switch(t)<br>
{<br>
case 1:<br>
y = 11; <br>
case 2:<br>
y = 9;<br>
x = 12;<br>
break;<br>
default:<br>
break;<br>
}<br>
}</font><br>
<br>
and I got something I didn't expect. The second CaseStmt does only contain the first statement that is under it's label. The "x=12;" gets its own Stmt outside the CaseStmt but inside the CompoundStmt inside the SwitchStmt. I would anticipate that all statements
under a label either are: inside the CaseStmt or: outside but inside the CompoundStmt. Any reason for this?.<br>
<br>
<br>
