What do you mean by "good results"?
Did you manage to run some non-trivial applications, e.g. SPEC2016 or at
least SPEC2000 under msan on 32-bit?
I am very skeptical about msan on 32-bits. It may appear to work on tests
(it will)
but on any non-trivial application it will hit scalability issues. Remember
that on 32-bit msan will be limited to 1G of application memory.
Also, if we are going to enable msan on 32-bit MIPS, we should first have
it enabled on 32-bit x86,
so that we can test 32-bit support on x86 bots. I know, that's a non-zero
cost to pay.
