From 54709339f53222b83c17a894f507309ed204e639 Mon Sep 17 00:00:00 2001 From: Pierre Muller Date: Tue, 20 Apr 2010 00:17:05 +0000 Subject: [PATCH] * win32-i386-low.c: Add 64-bit support. (CONTEXT_EXTENDED_REGISTERS): Set macro to zero if not exisiting. (init_registers_amd64): Declare. (mappings): Add 64-bit version of array. (init_windows_x86): New function.
