Re: [cdt-dev] Type promotion support?
|
Let me correct myself. The canonical way of getting _expression_ type is IASTExpression.getExpressionType(). It calls CPPVisitor.getExpressionType(IASTExpression _expression_) internally.

The extract function and extract local variable refactorings don't support type promotion:
int x = 3;
double y = (x + 2.5) * 15;
extract -------^^^^^^^^^
-> int x = 3;
int foo = x + 2.5; // foo should be a double
double y = foo * 15;
Are there existing methods that "merge" types (IASTDeclSpecifier), finding the correct shared type? For primitive types it's straightforward, but I'd like to avoid the bog of C++ types which override binary operators.
