feat: Merge SMT Terms in one class by Sarkoxed · Pull Request #5254 · AztecProtocol/aztec-packages

Sarkoxed · 2024-03-15T16:57:20Z

This pr brings major changes in symbolic terms usage.

STerm

A new class that is merged from FFTerm and FFITerm classes. Now you can use FFTerm or FFITerm by providing a TermType::FFTerm or TermType::FFITerm to STerm constructor.

All the operations are now stored in unordered_map<OpType, cvc5::Kind> operations. e.g. if the type is FFTerm, then operations[OpType::ADD] = cvc5::Kind::FINITE_FIELD_ADD, and operations[OpType::ADD] = cvc5::Kind::ADD for FFITerm

Also now you can use new BVTerm type. It can be used to solve constraints with lots of bitwise operations. However, it can be used only once all the optimizations are added. You simply can't use it to simulate finite field operations and it's not really optimal.

Symbolic variables can be initialized using new functions FFVar, FFIVar and BVVar

Solver

Added bv_sort member

Added bitvector operations parser to stringify_term

Circuit

No more templates. All the circuit methods are moved to .cpp file

Fixes:

range constraint is now made to be <= 2^n - 1 instead of < 2^n
changed xor_gate to logic_gate in info function
Removed setting optimized variables to zero, since it didn't affect anything except polluted output
Restored public_variables initialization. It was deleted some time ago. I don't know why.

Utils

smt_timer now has bool mins param, that tells in what format to output elapsed time

STerm: - fixed lots of errors in methods Tests: - fixed old ones to use STerm class - added new tests to check for unsupported functionality

- Switch to field_t native operations - Switch to the new STerm api - Use smt_timer

- removed zero initialization for optimized variables, since it doesn't do anything helpful - fixed logic_flag output - fixed range constraint so it now fits in bitvector size

What does this test do exactly?

What are the values 16 and 32?

What do we need this for?

I'm using this function in the two tests below. Since it is quite large, I decided to take it out separately.

Uhm. Why can't you replace it with multilication and non-zero?

Because of BitVectors. They are not supposed to be divided by each other(well at least not like the real division, truncated - maybe. At least for now they are not)

Benchmark results

No metrics with a significant change found.

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

Values are compared against data from master at commit 10ef9702 and shown if the difference exceeds 1%.
