Ah, but i386 and x86-64 do not:

libunwind-i386/include/libunwind.h:typedef long double unw_tdep_fpreg_t;
libunwind/include/libunwind.h:typedef long double unw_tdep_fpreg_t;
libunwind-ppc64/include/libunwind.h:typedef long double unw_tdep_fpreg_t;
libunwind-x86_64/include/libunwind.h:typedef long double unw_tdep_fpreg_t;

where to the SSE registers fit in to this?
