Experimental CFLAGS. To quote the gcc documentation: The following options control optimizations that may improve performance, but are not enabled by any `-O' options. This section includes experimental options that may produce broken code. ... -ftracer ... -fprefetch-loop-arrays ... At a minimum, take these out and "emerge -Dev system". I would also take out all of the mmx and sse flags, and let those be enabled by USE flags for those packages where it is known to be safe to do so. Finally, please turn off HTML email. -Richard -- gentoo-amd64@gentoo.org mailing list
