When compiling qemu 0.5.5 (http://fabrice.bellard.free.fr/qemu/), the following
error occurs:

As the log shows, I used the flags "-O2 -frename-registers -fomit-frame-pointer
-march=i686". Interestingly, the problem above doesn't occurs when I specify
-march={i386,i486,i586}, I only have an error when using i686/athlon/pentium4 (I
didn't test all combinations, probably other options greater than i686 are also
affected). To compile qemu with different flags, you must edit Makefile and
Makefile.target from qemu sources, using for example sed:

sed -i "s/CFLAGS=.*/CFLAGS=-O2 -frename-registers -fomit-frame-pointer
-march=i686/" Makefile{,.target}
