...ses where you want to
perform arithmetic and comparisons on pointers that the semantics of
GEP make illegal so the only way to do so in a target independent way
is to either cast to an int you hope is >= than any pointer, or
violate the GEP semantics (which is generally works).
GBP instruction (GetBasePointer). The inverse of a GEP. A GEP
selects an offset into a object in a target independent way based on
the type. What GBP would do would be to get a pointer to the base of
an object based on a pointer to field, a type, and the same specifier
as the GEP would use to get the field.
x == GBP (GEP x,...
