I believe that the libgcc.a in our toolchain contains Thumb-2 code. I verified this by doing objdump on libgcc.a and I see combinations of 16 and 32 bit instructions. So does that mean that the toolchain is only usable for ARM versions that support Thumb-2?
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.
