Hi,<br>
<br>
I am trying to transform all T a, b, c = ...; to single line declarations:<br>
<br>
T a;<br>
T b;<br>
T c = ...;<br>
<br>
This works well by matching for DeclStmt and iterating through the<br>
DeclGroup. Unfortunately, a global declared T a, b, c = ...; does not<br>
result in such a DeclStmt:<br>
<br>
<cpp><br>
int alone;<br>
int alone2 = 3;<br>
<br>
int notalone1, notalone2 = 4;<br>
<br>
int main(void)<br>
{<br>
int lalone;<br>
int lalone2 = 3;<br>
<br>
int lnotalone1, lnotalone2 = 4;<br>
<br>
}<br>
</cpp><br>
<br>

As you can see, each notalone is a VarDecl whereas VarDecl for lnotaloneX<br>
is grouped in a DeclStmt. Is there any other way to find all the<br>
init-declarator lists?<br>
<br>
Thanks!<br>
