right
I have been processing large source codes including STL, boost and
custom code including function bodies and I have never seen a
RANGE_EXPR. I suppose it's only used at later stages or only in other
language's frontends.
Incorrect. RANGE_EXPRs get generated during processing of an array's
initializer -- very early on in the C++ FE.
as said there have not been one case in large sources.
I can't recall exactly. It might be for default initialization.
Something like
ptr = new int[100] ();
...does not initialize anything
int ar[]={0,0,0,0}; does, but not with RANGE_EXPR
