From 7d12e522ba13ce718b7ec32b75803dece8adb072 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Thu, 5 May 2005 16:15:11 -0700 Subject: [PATCH] ppc64: remove hidden -fno-omit-frame-pointer for schedule.c While looking at code generated by gcc4.0 I noticed some functions still had frame pointers, even after we stopped ppc64 from defining CONFIG_FRAME_POINTER. It turns out kernel/Makefile hardwires -fno-omit-frame-pointer on when compiling schedule.c. Create CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER and define it on architectures that dont require frame pointers in sched.c code.
