From 4d1fd7f1ae6cf4e6e4e1cad975f1dcdea62b6d83 Mon Sep 17 00:00:00 2001 From: York Sun Date: Wed, 26 Feb 2014 17:03:19 -0800 Subject: Add 64-bit data support for memory commands Add 64-bit data for memory commands, such as md, mw, mm, cmp. The new size ".q " is introduced. For 64-bit architecture, 64-bit data is enabled by default, by detecting compiler __LP64__. It is optional for other architectures.
