ARM-optimized Goldilocks Poseidon (#294) * Optimized Poseidon for ARM * Hamish comments * Unused things 2021-10-30 14:32:39 -07:00			`mod arch;`
Move stuff around (#135) No functional changes here. The biggest change was moving certain files into new directories like `plonk` and `iop` (for things like `Challenger` that could be used in STARKs or other IOPs). I also split a few files, renames, etc, but again nothing functional, so I don't think a careful review is necessary (just a sanity check). 2021-07-29 22:00:29 -07:00			`pub mod gmimc;`

Native Poseidon implementation(s) (#207) * Simplify and refactor GMiMC benchmark. * Refactor/combine GMiMC and Rescue hash benchmarks. * Remove old Rescue bench; rename GMiMC bench. * Add from_canonical_u128 for fields. * Initial version of Poseidon. * Partial implementation of fast Poseidon. * Complete (but broken) implementation of fast partial rounds. * Fix index calculation. * Add basic tests. * Fix constants; fix bugs in fast partial round calculation. * Rename main functions. * Add test vectors. * Use x^7 for s-box monomial. * Fix s-box application in fast version. * Make WIDTH a parameter. * Working version with both widths. * Updated the constants so they use x^3; added test vectors. * Expand bench_hash to cover both widths and report relative slowdown. * Remove references to MaybeUninit. * First draft of refactoring the two Poseidon widths. * Tidy up use of conversion to/from raw data. * Add some comments. * Refactor tests. * Apply cargo fmt changes. * Have `Field`s implement `PoseidonInterface` (#209) * Have `Field`s implement `PoseidonInterface` Rather than having a sort of "dummy struct" implement `PoseidonInterface` with the field as a generic param. I think this seems more natural and type-safe. The type safety does come at a price -- it would be harder to do dynamic things such as taking `WIDTH` as a command line option -- but I think that's alright. * Fix missed conflicts. * cargo fmt fixes. * Fix to accommodate changes in latest nightly.

Implement Poseidon width 8 and 12 for Goldilocks field. (#268) * Implement Poseidon width 8 and 12 for Goldilocks field. * Comment on generating Poseidon implementations. * Update Goldilocks 8 constants with corrected MDS matrix. * Add Goldilocks test vectors and refactor tests. * Add test vectors of all -1's. * cargo fmt pedantry. 2021-09-28 10:51:03 +10:00			`pub mod poseidon_goldilocks;`
