Update of /cvsroot/sbcl/sbcl In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv16964 Modified Files: NEWS version.lisp-expr Log Message: 0.9.8.16: Merge sbcl-devel "Some assembler improvements for x86-64" by Lutz Euler on 2006-01-05. Quote from the email: 1. a reduction in core size of 190 KB due to shorter encodings for common forms of the MOV instruction, and 2. for robustness, better checking of dword-sized immediate arguments in the assembler with respect to their implicit sign-extension.
