Slamd64 is an unofficial port of Slackware® Linux to the x86_64 architecture. It was started from slackware-current in 2004, and was created by cross-compiling from scratch, rather than using an existing 64-bit distribution as a base.
Slamd64 is a multi-lib distribution, which means that you can run 32-bit applications easily, without a chroot. You can directly install most packages targeted at x86 Slackware®.
