Cipher Block chaining but with encrypting the plain text first then xor with IV
It is a really bad idea to have $$C_i = C_{i-1} \oplus E(P_i).$$ The ciphertext leaks a deterministic function of each plaintext block, as  $$C_i \oplus C_{i-1}  =E(P_i).$$ Now an eavesdropper can easily tell whether $P_i = P_j$ by checking whether $$C_{i-1} \oplus C_i = C_{j-1} \oplus C_j.$$
