From bc850d6b374fffd08336996f4b4d3bbd6bf427f6 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Wed, 30 Jan 2008 13:33:07 +0100 Subject: x86: add the capability to print fuzzy backtraces For enhancing the 32 bit EBP based backtracer, I need the capability for the backtracer to tell it's customer that an entry is either reliable or unreliable, and the backtrace printing code then needs to print the unreliable ones slightly different. This patch adds the basic capability, the next patch will add a user of this capability.
