Hi Rich,
Please refer to https://github.com/JaydeepIMG/musl-1 for MIPS64 N64 port.
I have also attached the patch with this mail.
Could you please find some time to review this?
Thanks,
Jaydeep

Sure. FYI OpenWRT is already testing this and it seems to be working
for them.
First some cosmetics -- applying the patch with git apply reported
whitespace errors (lines with trailing whitespace) that should be
fixed. There are also some lines with incorrect indention (spaces).
Running the following commands on the patch file will find some of
them:
grep '. *$'
grep '^+ '
Also, comments should be left out in public headers (bits) and there
may be some space/tabs issues (tabs should be used for intention,
spaces for alignment) in comments in the asm (I didn't check yet).

Where does the size 25 come from? I don't have any reason to think
it's wrong but I just want to check since it's an ABI issue and one
we've messed up on early ports in the past.

Here's a place where you have spaces instead of tabs.

And here, plus comments that should be removed.
Also the padding should not have names in public st_* namespace but
rather just __padN or similar.

Comments like this can be omitted; they don't say anything that the
code doesn't already say and we try to avoid comments in installed
headers too.

I would prefer doing like the existing 32-bit mips port and just
expanding the 5000, 5001, etc. directly. Use of the __NR_linux macro
just makes the source tree larger and makes it take longer to parse
and preprocess; it doesn't make it any more readable.

Inconsistent mix of tabs/spaces; should be all tabs for indenting.

The commented out oversized mask should be removed. I suspect
compilers will give a nested-comment warning for it as-is.

This should also have mips-specific R_* defs; see below.

I don't think the memsets are necessary, and they're going to make the
calling function big/messy because they add extra external calls.

All __syscallN for N>=2 should do the stat fix (as on 32-bit mips);
otherwise, adding unused args to the syscalls would break. This
especially affects src/misc/syscall.c which provides the public
syscall() function. The compiler will optimize out the code anyway
when n is a constant.

This should be moved into arch/mips64/reloc.h rather than using an
arch-specific #ifdef in a shared file.
Also _GNU_SOURCE cannot be defined "late"; feature test macros have to
appear before any system header is included. You can just assume the
file including it has defined whatever's needed to make the endian.h
functions visible, I think. Let me know if that's not working.
That's all I saw for now. I'm also running a build and test of my own
right now so I'll let you know if I see anything else that doesn't
look right.

This is wrong and not working:

a_ll_p must return the loaded value which has pointer type, not int.

These should be copied from aarch64 or x86_64 (should be same)
instead.
Nothing else showed up just from warnings but I'll take a second look
at the source and see if anything else related looks wrong.

Hi Rich,
Thanks for the comments.
Please refer to https://github.com/JaydeepIMG/musl-1 for MIPS64 N64 port.
I have created mips64port_v2 branch (patch attached) to address the review comments.
Thanks,
Jaydeep

These are still the 32-bit definitions not the 64-bit ones.

pad1, pad2 etc. are in the application-reserved namespace. These need
to be __pad1, __pad2, etc. or similar. -- something reserved.

When I said the memset can be removed I didn't mean to replace it with
assignments. Although they're not as bad, I don't see any reason
they're needed at all. The padding does not need to contain meaningful
content. Just leaving it uninitialized is fine.
Also, the return statement is not needed.

I didn't catch this before, but is there a reason you're filling kst
with zeros before passing it to the kernel? I don't think it's useful,
and it generates extra code the compiler cannot optimize out (because
it cannot know the kernel won't read the memory). Same applies for all
the oher __syscallN's.
The rest of your changes all look okay.
Since it looks like it's about ready to commit, I have a couple
general questions about merging. How should the port be credited? To
imgtec.com? Should someone on your team be the commit author in the
commit, or should I just commit it in my name with your team credited
in the commit message and COPYRIGHT file?
Thanks for your work on this and your patience with review. :)

Ok.
Please refer to https://github.com/JaydeepIMG/musl-1 for MIPS64 N64 port.
I have created mips64port_v3 branch (patch attached) to address the review comments.

You can credit it to Imagination Technologies.
Could you please commit it with "Mahesh Bodapati and Jaydeep Patil" in the message?
>Thanks for your work on this and your patience with review. :)

Thanks for your comments :)

I found one more bug -- this second definition of mcontext_t
needs to match the real version in size and alignment, but be
namespace-safe. As-is it's just copied from o32. I'll fix it when
committing though; the fix is trivial.

I'm going to commit these two changes first as their own patch because
they're the only ones that touch files outside the mips64 port. Then
the mips64 commit will be purely adding new files and not modifying
any existing code.
I didn't find anything else that looks like a blocker; if other issues
come up we can simply commit fixes. Going ahead and getting the port
committed should help get some more testing done before the next
release so we can have it well-tested by then. Thanks for all your
work on this!
