Hi Rich,
Please refer to https://github.com/JaydeepIMG/musl-1/tree/mipsn32port for MIPS64 N32 port. I have also attached the patch (ipsn32port.patch) for your reference.
Could you please review it?

Thanks! I haven't gotten a chance to review it yet but I want you to
know that I've seen it and will try to get to it in the next few days.
If anyone else wants to take a look/try it and comment on it in the
mean time, please go ahead; that will be helpful when I get to looking
at it myself too.

I'm at ELC now and haven't yet had a good chance to look over it in
detail, but I just looked at it as a diff against the mips64 tree and
it looks mostly okay. There are a few things that changed from nsz's
bits cleanups, and the mips r6 patch I committed, that should also be
applied to n32. I can make those changes myself if you like but I
probably won't get to it until Friday or later (my flight gets back
Thursday night); if you'd rather submit an updated patch that's fine
too.

I tested this on my flight back and it seems to be mostly working,
except for configure failing to detect n32. Some comments inline:

I think __mips<2 is mutually exclusive with 64-bit so it should be
okay to omit this.

This pattern does not seem to match any tuple actually used; it
doesn't even have a glob * in it. On my first try, I got a heap of
warnings and a broken build because musl detected the n32 compiler as
mips64.
It doesn't seem to be possible to detect from the tuple that a
compiler is n32, so I think the right fix is something like:
@@ -618,6 +619,7 @@ trycppif __mips_soft_float "$t" && SUBARCH=${SUBARCH}-sf

+trycppif "_MIPS_SIM != _ABI64" "$t" && ARCH=mipsn32
trycppif "__mips_isa_rev >= 6" "$t" && SUBARCH=${SUBARCH}r6
trycppif "_MIPSEL || __MIPSEL || __MIPSEL__" "$t" && SUBARCH=${SUBARCH}el
trycppif __mips_soft_float "$t" && SUBARCH=${SUBARCH}-sf
Alternatively, instead of depending on the predefined macros we could
compile a test program that errors out depending on sizeof(void*)
being 4 vs 8. If we take the latter option, a new trystaticassert
function should probably be added to configure to make it easy to
reuse the logic. But I think the preprocessor version is okay for now.
I'd really like to transition the configure script to only using the
-dumpmachine tuple as a hint, and only when it's available, and
checking predefined macros and such to verify the arch.

This hunk would become unnecessary then.

I don't think the move $sp, $25 is needed here. If you read the git
history for why it was added, it way to work around an o32 kernel bug
that does not affect other ABIs. The git log message references the
relevant kernel commit and I checked the kernel git history and
verified that the affected code is o32-only.
Otherwise, it looks very good. Thanks for working on this and for your
patience. If the above suggested changes look okay with you I can make
them and commit it.
