CBMC: Add x86-64 HOL-Light-based contracts and proofs
- This commit introduces CBMC verification for several x86-64 optimized assembly functions. The contracts for these functions are derived from their corresponding HOL-Light correctness proofs. - For each assembly function, a CBMC contract has been added to `arith_native_x86_64.h`. Additionally, new proof harnesses have been creat to formally verify that the generic C implementations (`*_native`) correctly utilize these assembly backends and adhere to the top-level API contracts. - The following functions now have CBMC proofs based on their HOL-Light specifications: - polyvec_basemul_acc_montgomery_cached_asm_k2/k3/k4: - Pre-conditions: `<= &2 pow 12`(HOL_LIGHT) v.s. `MLKEM_UINT12_LIMIT + 1`(CBMC) - Adds a CBMC pre-condition: `requires(array_abs_bound(a, 0, 4 * MLKEM_N, MLKEM_UINT12_LIMIT +` `1))` - ntt_avx2: - Pre-condition: `<= &8191`(HOL_LIGHT) v.s. `8191 + 1`(CBMC) - Post-condition: `<= &23594`(HOL_LIGHT) v.s. `23594 + 1`(CBMC) - Adds a CBMC pre-condition: `requires(array_abs_bound(r, 0, MLKEM_N, 8192))` - Adds a CBMC post-condition: `ensures(array_abs_bound(r, 0, MLKEM_N, 23595))` - intt_avx2: - Post-condition: `<= &26631` v.s. `26631 + 1`(CBMC) - Adds a CBMC post-condition: `ensures(array_abs_bound(r, 0, MLKEM_N, 26632))` - reduce_avx2: - Post-condition: `< &3329`(HOL_LIGHT) v.s. `3329 == MLKEM_Q`(CBMC) - Adds a CBMC post-condition: `ensures(array_bound(r, 0, MLKEM_N, 0, MLKEM_Q))` - tobytes_avx2: - Pre-condition: `num_of_wordlist (MAP word_zx l:(12 word)list))`(HOL_LIGHT) v.s. `MLKEM_UINT12_LIMIT`(CBMC) - Adds a CBMC pre-condition: `requires(array_bound(a, 0, MLKEM_N, 0, MLKEM_UINT12_LIMIT))` - frombytes_avx2: - Post-conditions: `read (memory :> bytes(a,dimindex(:32) * 12)) s0 = num_of_wordlist (l:(12 word)list)` - Adds a CBMC post-condition: `ensures(array_bound(r, 0, MLKEM_N, 0, MLKEM_UINT12_LIMIT))` - mlk_rej_uniform_asm: - This proof are reference from aarch64 one, and change requires: `requires(buflen % 24 == 0)` to `requires(buflen % 12 == 0)` - mlk_tomont_avx2: - Post conditions: `(ival z_i == (tomont_3329 (ival o x)) i) (mod &3329) /\ abs(ival z_i) <= &3328)` v.s. `ensures(array_abs_bound(r, 0, MLKEM_N, MLKEM_Q))` - Add a CBMC post-condition: `ensures(array_abs_bound(r, 0, MLKEM_N, 3328 + 1))` Signed-off-by: willieyz <[email protected]>
