Can you post or email me privately the full patch? I can try to see what I
spot.
Can you check with objdump or gdb that the methods which don't appear to
work
are actually the RISC-V implementation? Look at the disassembly and see if
it
looks like you expect.
Does this require a patch to newlib as well?
