[movitz-cvs] CVS update: movitz/compiler.lisp
by Frode Vatvedt Fjeld 23 Jul '04

23 Jul '04

Update of /project/movitz/cvsroot/movitz In directory common-lisp.net:/tmp/cvs-serv24640 Modified Files: compiler.lisp Log Message: Fixed a bug in resolve-borrowed-bindings wrt function-bindings: Sometimes we would generate a forwarding-binding to a function-binding, but the forwarding-binding-target would be nil because this function returned nil for function-bindings. Also, started to use a new strategy with thunks in analyze-bindings.
