[LLVMdev] llvm::ConvertibleToGEP

[Naftali Schwartz]

I'm sorry, it had seemed to me that the documented functionality:

// ConvertibleToGEP - This function returns true if the specified value V 
is
// a valid index into a pointer of type Ty.  If it is valid, Idx is filled 
in
// with the values that would be appropriate to make this a getelementptr
// instruction.  The type returned is the root type that the GEP would 
point to

would be quite useful (and in particular for dependence analysis).
Are you going to remove it because it's functionality is already present 
elsewhere or is simply not needed anymore?
