[cfe-dev] Getting the value of a IntegerLiteral

[Jesper Eskilson]

Hi,

I'm trying to figure out how I can obtain the value of an 
IntegerLiteral. I tried the following:

const IntegerLiteral *lit = ...;
if (lit != 0)
{
     int64_t n = lit->getValue().getSExtValue();
     // do something with n
}

This seems to work sometimes, but frequently crashes. I've tried to 
figure out how to use the Evaluate*-functions in the Expr class, but I 
cannot figure out how they should be called.

It's ok if obtaining the value sometimes fails, but it would be nice if 
it didn't crash. :)
