The [[Standard ML#Implementations|CakeML]] project developed a formally proven compiler for ML.<ref>{{Cite web | url=https://cakeml.org/ |title = CakeML}}</ref> Previously, HOL was used to develop a formally proven [[Lisp (programming language)|Lisp]] implementation running on ARM, x86 and PowerPC.<ref>{{cite conference|author1=Magnus O. Myreen|author2=Michael J. C. Gordon|title=Verified LISP Implementations on ARM, x86 and PowerPC|conference=TPHOLs 2009|pages=359–374|url=https://www.cl.cam.ac.uk/~mom22/tphols09-lisp.pdf}}</ref>

HOL was also used to formalize the [[semantics (computer science)|semantics]] of x86 multiprocessors<ref>{{cite journal|author1=Peter Sewell|author2=Susmit Sarkar|author3=Scott Owens|author4=Francesco Zappa Nardelli|author5=Magnus O.
