Revision b8a711adaa9d1e66eb537f492f2c5435cb748620 authored by Andrew Adams on 07 January 2022, 18:57:42 UTC, committed by GitHub on 07 January 2022, 18:57:42 UTC
* Make random 2x faster by putting the innermost var last * Improve period of low bits of random noise * Add new rewrite rules for quadratics By pulling constant additions outside of quadratics, we can shave off a few add instructions in the inner loop for random number generation, which uses a quadratic modulo 2^32 I also removed the !overflows predicates, because rules already fail to match if a fold overflows. New rules formally verified. * Make expensive_zero actually always zero * Partially revert new simplifier rules * Enable new rules * Revert test Co-authored-by: Steven Johnson <srj@google.com>
