Our focus is Thumb-2 on Cortex-A processors. We try to 'do no harm',
so Linaro GCC should be as good as the FSF GCC on older ARM
architectures or non-ARM architectures such as i686 and x86_64.
The included libgcc is compiled for processors with Thumb-2 and
VFPv3-D16. I'm afraid I have no plans for other variants at the
moment, but you might want to talk with Marcin and Wookey about this.
