From 1652fcbf37abdbbebaf386b46b20e486769e7b45 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 2 May 2007 19:27:08 +0200 Subject: [PATCH] x86-64: Don't disable basic block reordering When compiling with -Os (which is default) the compiler defaults to it anyways. And with -O2 it probably generates somewhat better (although also larger) code.
