From c0a80c0c27e5e65b180a25e6c4c2f7ef9e386cd3 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 9 Jan 2015 13:06:33 +0100 Subject: ftrace: allow architectures to specify ftrace compile options If the kernel is compiled with function tracer support the -pg compile option is passed to gcc to generate extra code into the prologue of each function. This patch replaces the "open-coded" -pg compile flag with a CC_FLAGS_FTRACE makefile variable which architectures can override if a different option should be used for code generation.
