From 5e8287d2e2eaf058495442ea9e32fafc343a0b53 Mon Sep 17 00:00:00 2001 From: Nathanael Premillieu Date: Wed, 5 Apr 2017 12:46:06 -0500 Subject: arch, cpu: Architectural Register structural indexing Replace the unified register mapping with a structure associating a class and an index. It is now much easier to know which class of register the index is referring to. Also, when adding a new class there is no need to modify existing ones.
