From cc80ae38bfb698559c8f728d9f0c7b20ed4a59e6 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Tue, 27 Aug 2013 13:52:51 +0530 Subject: Kconfig.debug: Add FRAME_POINTER anti-dependency for ARC Frame pointer on ARC doesn't serve the conventional purpose of stack unwinding due to the typical way ABI designates it's usage. Thus it's explicit usage on ARC is discouraged (gcc is free to use it, for some tricky stack frames even if -fomit-frame-pointer). Hence no point enabling it for ARC.
