EVM Arithmetic Stark table (#559) * First draft of 256-bit addition. * Update comment. * cargo fmt * Rename addition evaluation file. * Port ALU logic from SZ. * Give a name to some magic numbers. * `addition.rs` -> `add.rs`; fix carry propagation in add; impl sub. * Clippy. * Combine hi and lo parts of the output. * Implement MUL. * Suppress Clippy's attempt to make my code even harder to read. * Next draft of MUL. * Make all limbs (i.e. input and output) 16-bits. * Tidying. * Use iterators instead of building arrays. * Documentation. * Clippy is wrong; also cargo fmt. * Un-refactor equality checking, since it was wrong for sub. * Daniel comments. * Daniel comments. * Rename folder 'alu' -> 'arithmetic'. * Rename file. * Finish changing name ALU -> Arithmetic Unit. * Finish removing dependency on array_zip feature. * Remove operations that will be handled elsewhere. * Rename var; tidy up. * Clean up columns; mark places where range-checks need to be done. * Import all names in 'columns' to reduce verbiage. * cargo fmt * Fix aux_in calculation in mul. * Remove redundant 'allow's; more precise range-check size. * Document functions. * Document MUL instruction verification technique. * Initial tests for ADD. * Minor test fixes; add test for SUB. * Fix bugs in generate functions. * Fix SUB verification; refactor equality verification. * cargo fmt * Add test for MUL and fix some bugs. * Update doc. * Quiet incorrect clippy error. * Clean up 'decode.rs'. * Fold 'decode.rs' into 'arithmetic_stark.rs'. * Force limb size to divide EVM register size. * Document range-check warning and fix end value calc. * Convert `debug_assert!`s into `assert!`s. * Clean up various kinds of iterator usage. * Remove unnecessary type spec. * Document unexpected use of `collect`. 2022-06-29 11:56:48 +10:00			`mod add;`
EVM arithmetic unit: unsigned comparisons (#688) * Refactor u256 calculation; return cy/br from calculations. * Implement less than and greater than operations. * Add file documentation. 2022-08-26 09:13:47 +10:00			`mod compare;`
Modular operations for the EVM arithmetic unit (#755) * First draft of 256-bit addition. * Update comment. * cargo fmt * Rename addition evaluation file. * Port ALU logic from SZ. * Give a name to some magic numbers. * `addition.rs` -> `add.rs`; fix carry propagation in add; impl sub. * Clippy. * Combine hi and lo parts of the output. * Implement MUL. * Suppress Clippy's attempt to make my code even harder to read. * Next draft of MUL. * Make all limbs (i.e. input and output) 16-bits. * Tidying. * Use iterators instead of building arrays. * Documentation. * Clippy is wrong; also cargo fmt. * Un-refactor equality checking, since it was wrong for sub. * Daniel comments. * Daniel comments. * Rename folder 'alu' -> 'arithmetic'. * Rename file. * Finish changing name ALU -> Arithmetic Unit. * Finish removing dependency on array_zip feature. * Remove operations that will be handled elsewhere. * Rename var; tidy up. * Clean up columns; mark places where range-checks need to be done. * Import all names in 'columns' to reduce verbiage. * cargo fmt * Fix aux_in calculation in mul. * Remove redundant 'allow's; more precise range-check size. * Document functions. * Document MUL instruction verification technique. * Initial tests for ADD. * Minor test fixes; add test for SUB. * Fix bugs in generate functions. * Fix SUB verification; refactor equality verification. * cargo fmt * Add test for MUL and fix some bugs. * Update doc. * Quiet incorrect clippy error. * Initial implementation of ADDMOD and MOD. * Fixes to addmod. * Update doc. * Do 1000 random tests instead of just 1. * Documentation fix. * Working version of ADDMOD. * Working version of MOD. * Name magic number; do multiple MUL tests. * Add code and test for special case; add some docs. * Fix spelling mistake. * Simplify asserts. * Tidy comment. * Remove unused module. * cargo fmt * Check that output is reduced. * Add conversion of canonical `i64` to a `Field64`. * Handle zero modulus within degree constraint. * cargo fmt * Fix some comments. * Check that the top half of the product is zero! * Start of refactor. * Refactoring. * Remove zero and reduction handling from addmod. * Refactoring; renaming; bug fixes. * Reuse intermediate calculations across all modular operations; don't negate quot poly unnecessarily. * Fix bug where last elt of qm wasn't checked. Refactoring. * Move circuit poly functions to utils.rs. * Rename ADDMOD stuff to MODULAR. * Rename module addmod -> modular. * Handle zero modulus. * Verify that output is reduced. * Implement recursive version of modular circuits. * clippy * Tidy up i64 -> Field conversion following Jacqui's comments. * cargo fmt * Improved documentation. * Address Jacqui's comments. * Save some gates by using builder.arithmetic_extension(). 2022-10-07 17:15:50 +11:00			`mod modular;`
