Begin by making a
copy of the file called trap.handler: call the copy
trap.handler.original. You will work on the file
trap.handler which the SPIM simulator loads by default.
Look at the file and, based on what you see, try to answer a few
questions. The ‘.set noat’ assembler directive instructs the
assembler not to complain about using the $at
register (which is reserved for the assembler’s usage).
Q2: Is the exception
handler you find in the file trap.handler re- entrant or
not? Explain. A possible comment in the code that says the handler
is not re-entrant is not a good argument! There are several
possible explana- tions, but you need provide only one.
