From: Didier Verna on 23 Apr 2008 06:02 Hello, I would like to have an idea of how much of the lisp compilers you know are written in lisp and how much is written in something else. A similar but probably a bit different question is: how much of the lisp compilers you know involves lisp-level program transformation, and how much actually involves traduction to machine code ?

And how much involves intermediate code transformation and optimization. IIRC, in sbcl it's the most part of the compiler. Also, you could consider that all the macros, being compiler hooks, are lisp-level program transformations, and weight heavily on that side. -- __Pascal Bourguignon__

About Lispworks, I don't know. Best Regards, Christophe

So, you actually don't know much about Real Common Lisp in Real World, do you :-p -- 5th European Lisp Workshop at ECOOP 2008, July 7: http://elw.bknr.net/2008/ Didier Verna, didier(a)lrde.epita.fr, http://www.lrde.epita.fr/~didier EPITA / LRDE, 14-16 rue Voltaire Tel.+33 (0)1 44 08 01 85 94276 Le Kremlin-Bic�tre, France Fax.+33 (0)1 53 14 59 22 didier(a)xemacs.org |
