I've gotten the MIPS port up to where it can compile and execute through about
9 functions of a testcase before it crashes.
The reason for the crash appears to be related to op_put_by_id. When this
opcode is compiled, the JIT executes:

It's cool that you are working on a MIPS port of the JIT. However, it's
somewhat off-topic to ask for help with private ports here. There's also not
much we can do to help

I've tracked down a crash in our JIT port to a problem with the trampoline
generation.
The symptom of the crash is: the ScopeChain becomes corrupted and acquires the
value of 1.

I don't understand this code in JITStubs::cti_op_call_arityCheck():
ASSERT(argCount != newCodeBlock-m_numParameters);
It's
ensuring that the argument count does not equal the number of
parameters expected by the newCodeBlock. I could understand if it was
ensuring the argCount was the same,
Thanks guys.
One request - please write more comments in the code to clarify situations like
this.
