From a137802ee839ace40079bebde24cfb416f73208a Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 12 Jul 2009 11:25:04 -0700 Subject: [PATCH] Don't use '-fwrapv' compiler option: it's buggy in gcc-4.1.x This causes kernel images that don't run init to completion with certain broken gcc versions. This fixes kernel bugzilla entry: http://bugzilla.kernel.org/show_bug.cgi?id=13012 I suspect the gcc problem is this: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28230 Fix the problem by using the -fno-strict-overflow flag instead, which not only does not exist in the known-to-be-broken versions of gcc (it was introduced later than fwrapv), but seems to be much less disturbing to gcc too: the difference in the generated code by -fno-strict-overflow are smaller (compared to using neither flag) than when using -fwrapv.
