There was a problem hiding this comment.
R1CSResult::default() only requires the num_cons value from the R1CSShape. If we change the function to take this value instead, then we can more simply compute
let max_num_cons = *pp.circuit_shapes.iter().map(|shape| shape.num_cons).max().unwrap();
let buffer_primary = ResourceBuffer {
l_w: None,
l_u: None,
ABC_Z_1: R1CSResult::default(max_num_cons),
ABC_Z_2: R1CSResult::default(max_num_cons),
T: r1cs::default_T(max_num_cons),
};

* Small perf items (lurk-lab#12) * Optimize generator creation in provider module - Refactored the `from_label` function in pasta.rs removing redundant collect, flatten operations and Vec<usize> creation, * fix: rename VanillaRO -> NativeRO * refactor: Optimize circuit methods and enhance trait compatibility - Replaced the `.map()` function with the `.map_or()` function in `r1cs.rs` for efficiency. - Added `Eq` trait derivation to `NovaAugmentedCircuitParams` in `circuit.rs` to enable comparisons. - Introduced `Eq` trait to `TrivialTestCircuit` struct in `traits/circuit.rs` without altering its input or output. - Optimized performance by refactoring the use of iterator `into_iter()` to the iterator itself in `gadgets/r1cs.rs`. * ci: Bring clippy standards lurk-rs -> arecibo (lurk-lab#13) * ci: Bring clippy standards lurk-rs -> arecibo - Added a new .cargo/config file with a custom alias "xclippy" to execute Clippy lints for code quality assurance, - Fixed code correspondingly when necessary, - Added xclippy to CI * chore: add dbg_macro to ci's clippy - Implemented a new clippy lint for the dbg_macro in the cargo config file * test: Extend tests to add missing curve variants (lurk-lab#33) - Enhanced testing for multiple modules, including bellpepper, spartan, and provider, focusing on the addition and multiplication of multi-linear polynomials and the Keccak transcript. - Introduced usage of secp256k1::Scalar (and sometimes bn256_grumpkin::bn256::Scalar) into tests for improved coverage.

Resolves the next step of #137.
This PR brings the changes done to the Nova memory pipeline in #139, #143, and #144 to SuperNova as well. Since the core logic was already established in the previous Nova PRs, this PR mostly just refactors and cleans up the SuperNova API.
Notes:
R1CSShape::multiply_vec, since it's still in(pp)snark.rs. The concatenation ofz = W.W ++ U.u ++ U.Xhappens anyways, so we can keep the instances ofS.multiply_vec(z)for readability.
