You may download the code and access the documentation on the following URL:

Instructions for submitting patches may be found here:

That said, how do you handle the case of getting a fault while reading
code/data while unwinding?
Also I don't see how you handle these cases:
o Leaf functions where neither the $ra is saved to the stack, nor the
stack pointer adjusted.
o Functions where $sp is adjusted several times (use of alloca() or VLAs).
o Functions with multiple return points (i.e. 'jr $ra' in the middle of
a function).
o Functions with more than 1024 instructions.
Thanks,
David Daney
