Subject: [PATCH 2/3] powerpc: Remove -fno-omit-frame-pointer workarounds
Date: Sat, 2 May 2009 04:14:22 +0400 [thread overview]
Message-ID: <20090502001422.GB9342@oksana.dev.rtsoft.ru> (raw)
In-Reply-To: <20090502001329.GA11549@oksana.dev.rtsoft.ru>
The workarounds aren't needed any longer since the top level Makefile
doesn't pass -fno-omit-frame-pointer cflag for PowerPC builds.
