From 8833b50cbf9a89653b1c77f81fc661e59e0cbae4 Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Sun, 20 Jan 2008 22:26:03 +0800 Subject: [PATCH] nios2: remove last br in inthandler With current 8 bytes alignment of ENTRY, it is faster to fall through nop pad. It is safe to remove the last br to ret_from_interrupt.
