From 05f96ef1189ecbf2e8548056a0ca016e4f630cef Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 30 Nov 2006 20:44:49 +0000 Subject: [ARM] Allow gcc to optimise arm_add_memory a little more For some reason, gcc was calculating meminfo.bank[meminfo.nr_banks] repeatedly. Use a pointer to it instead.
