From 25ae9c1d8bbfeb6c00eccb4297a5937d8375a44a Mon Sep 17 00:00:00 2001 From: Wen Congyang Date: Mon, 7 May 2012 12:08:56 +0800 Subject: target-i386: add API to get dump info Dump info contains: endian, class and architecture. The next patch will use these information to create vmcore. Note: on x86 box, the class is ELFCLASS64 if the memory is larger than 4G.
