I didn't see any response to my point in 
<https://sourceware.org/ml/libc-alpha/2014-01/msg00382.html> that the 
actual ucontext ABI, as used by both the kernel and previous glibc, should 
use something other than __SH_FPU_ANY__ as the conditional for FPRs being 
part of the context.  I'm not sure exactly what - is __SH4__ defined in 
all relevant cases or do you need to test __SH4A__ as well (it looks like 
GCC might not define __SH4__ in all SH4A cases)? - but it certainly seems 
to me that the ABI has the FPRs in the context (just not used there, but 
affecting the size and layout) for soft-float SH4.
