hex.xor_hex_to_ptr (arity 3)

Effectively:  hex.xor *ptr[:n], hex[:n]
ptr is a hex[:w/4] that holds an address, which we assume is an hex-variable, which is dw-aligned.

Signature

def xor_hex_to_ptr n, ptr, hex { ... }

Defined in hex/pointers/xor_to_pointer.fj — lines 54–57 (view on GitHub).

Complexity

• Time: n(w(0.5@+2)  + 14@+26)

• Space: n(w(0.9@+17) + 10@+131)

See the complexity glossary for what @, w, dw, dbit, n mean.
