This site is for community-driven development for the basic ACL2 libraries, which deal with topics like arithmetic, data structures, and hardware modelling. We're working with the authors of ACL2 and our changes are eventually incorporated into official ACL2 releases.

Performance Comparisons

The statistics below correspond to runs of make ACL2_JOBS=8 regression using community books (available from the acl2-books project website), skipping directory books/clause-processors/SULFA/, for ACL2 executables built on Linux platforms as indicated. Not shown are results of testing on Windows and Mac OS X. Each regression was run on Ubuntu Linux.
