| Uphantom_var of Backend_var.t(*

The phantom-let-bound variable is an alias for another variable.

*)
| Uphantom_offset_var of {
var : Backend_var.t;
offset_in_words : int;
}
(*

The phantom-let-bound-variable's value is defined by adding the given number of words to the pointer contained in the given identifier.

*)
| Uphantom_read_field of {
var : Backend_var.t;
field : int;
}
(*

The phantom-let-bound-variable's value is found by adding the given number of words to the pointer contained in the given identifier, then dereferencing.

*)
| Uphantom_read_symbol_field of {
sym : string;
field : int;
}
(*

As for Uphantom_read_var_field, but with the pointer specified by a symbol.

*)
| Uphantom_block of {
tag : int;
fields : Backend_var.t list;
}
(*

The phantom-let-bound variable points at a block with the given structure.
