From eeec69dc06a0b87a578f4935bbd699d03bc4f359 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 21 Jun 2012 17:57:19 +0200 Subject: [PATCH] target-xtensa: drop usage of prev_debug_excp_handler Chains of exception handlers are currently unused feature. Dropping it to be consistent with target-i386 but it may simplify qom-ifying CPU in future like for target-i386.
