From 49cf78ef7bb34833496d59b6dfe84ae51b1ab097 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 12 Aug 2013 15:00:51 -0400 Subject: tile: support FRAME_POINTER Allow enabling frame pointer support; this makes it easier to hook into the various kernel features that claim they require it without having to add Kconfig conditionals everywhere (a la mips, ppc, s390, and microblaze). When enabled, it basically eliminates leaf functions as such, and stops optimizing tail and sibling calls. It adds around 3% to the size of the kernel when enabled.
