From 12db50c89584938839e035da47d206250cbfd7c2 Mon Sep 17 00:00:00 2001 From: Nikos Nikoleris Date: Mon, 13 Mar 2017 18:19:08 +0000 Subject: ruby: Add support for address ranges in the directory Previously the directory covered a flat address range that always started from address 0. This change adds a vector of address ranges with interleaving and hashing that each directory keeps track of and the necessary flexibility to support systems with non continuous memory ranges.
