Please post this separately, it can be reviewed and go in before the
actual port goes in.

It's odd to define this in an installed header.  I think it's unused
anyway.  Looks like yet another hppa remnant.

Would it be clearer to use memcpy here?  The generated code is likely
the same.

_dl_reloc_bad_type is unreachable here.

Likewise.

The fini argument to __libc_start_main is unused, so this shouldn't be
necessary.

I think it's more future-proof to use the appropriate compiler builtin.

I think this is outdated, see above.

Would it be possible to make the __clone function not varargs?  Or is
this too big a portability hazard?

Does OpenRISC really have a dynamic page size?

I do not see any of the required support code for this.

This should use unsigned long int.

This is no longer true for our posix_spawn implementation.

But this file should be unused anyway.  Can you remove it?

Likewise, this should use unsigned long int.  I suspect you can use
INTERNAL_SYSCALL_CALL directly, too.

Should use long int throughout.  Also applies to sysdep.h below.

Please post this separately, it can go in immediately.

This is not a complete review; I can't comment on the
architecture-specific bits, the atomics, and the math interfaces.

There are a few TODOs/TO-DOs left, please have a look.

You also need to document which ABIs are supported (in INSTALL, with a
brief entry in NEWS).  Are any specific GCC and binutils version
requirements, or kernel header requirements (beyond the already
documented minimums)?

I see a bunch of ifdef's for hard float, but this appears to be a
hard-float-only port.

Thanks,
Florian

This is missing a build-many-glibcs.py update.  You always need to include 
such an update with a new port, which must build at least one 
configuration for each ABI supported by the port (and may build any major 
non-ABI variants that seem relevant).  build-many-glibcs.py results for 
the port must be clean (i.e. no failures in the compilation part of the 
testsuite), at least when building with GCC and binutils master (it's OK 
if you need features or bug fixes not in the most recent release branches, 
although distributors might prefer such fixes to be backported).  
Similarly, there should be NEWS and README updates.

New 32-bit ports should preferably be set up to support only 64-bit time 
and 64-bit offsets (see ARC and RV32 patch postings for examples).

> diff --git a/sysdeps/or1k/bits/atomic.h b/sysdeps/or1k/bits/atomic.h

There should be no such file.  bits/ is only for installed headers, not 
internal ones.  See commit de071d199a8578055edf2722114788ae749823aa ("Move 
bits/atomic.h to atomic-machine.h (bug 14912).", 11 Sep 2015).

Do you really need this file?  See commit 
1270fbaaeebe642db335fccaaf98c82e6647cc0d ("semaphore: consolidate arch 
headers into a generic one", 5 May 2020).

See commit cb403c34c6f6e1cce5018864485958cfc2e28906 ("Remove relro 
configure test.", 27 Jun 2014).

When you have an old out-of-tree port, it's a good idea to go through 
cross-architecture commits from when the port was first created onwards to 
identify such global changes that need to be applied to that port.

> diff --git a/sysdeps/unix/sysv/linux/or1k/bits/mman.h b/sysdeps/unix/sysv/linux/or1k/bits/mman.h

You shouldn't have this file.  See the comment in 
sysdeps/unix/sysv/linux/bits/mman.h (and commit 
d3a43e49f342c4663af0fff9d95000cfe26867c3, "Unify many bits/mman.h

You'll probably need a newer minimum kernel when requiring 64-bit time 
support, until all the fallback for 64-bit time on 32-bit kernels without 
the 64-bit-time syscalls is implemented.

> +#undef __ASSUME_SET_ROBUST_LIST

Are you sure this is never supported on this architecture?  
arch/openrisc/include/asm/futex.h appears to have gained 
futex_atomic_cmpxchg_inatomic in 4.11, so I'd expect the #undef only to be 
for kernels older than that.

> diff --git a/sysdeps/unix/sysv/linux/or1k/sys/procfs.h b/sysdeps/unix/sysv/linux/or1k/sys/procfs.h

See commit d62f9ec0cce26a275ec68f4564814041a33395b1 ("Complete 
sys/procfs.h unification.", 25 Sep 2018).  You shouldn't have an 
architecture-specific version of this file; add whatever bits/ headers are 
needed instead.

In general, each architecture-specific file needs a justification that 
either no generic version exists or the generic one is unsuitable or 
suboptimal for this architecture; the default is that we want to use 
unified implementations of as many files as possible.

I did try to do this, but it started in 2014 it was hard to pick up everything.
I also payed close attention to the riscv and csky ports.

Sorry, I overlooked this thanks for catching.  I added the atomic support to the
kernel.

This has also been my goal for OpenRISC (use as much generic code as possible),
but when going over the original port I missed some of these.  I noticed in the
last few months since I started fixing up the port that many more architecture
specific parts were moved to generic code and I did those moves.  I seem to
missed everything from before 2019 when I started the port.

Thank you for pointing these out.

I will work on cleaning this up, testing and posting a new version in a week or
two.

OK. I missed this I started forward porting this old port around 2019 November
and must have missed that this was removed.

OK.

Copy paste, during forward porting I thought I removed a lot of these,  I will
clean it up and grep for similar patterns.

That would mean overriding the definition in sched.h?

This is the approach we used in other libc ports.

I think not, I must have added this before I understood about the search path.

Its not dynamic, but the issue I was fixing here was to allow getting the page
size from the kernel.  The default 4K value was causing issues with clone if I
remember.

Let me test this again.

OK, I will split it out.

OK, I will look, must have missed them.

OK.

For binutils and gcc require patches which are mentioned in the cover letter.
I will document.

I should support both hard fliat and soft float, but have not tested soft float
yet.  Let me test to see what would break.

Thanks for the review, I am happy that I can remove a lot of code and clean up
the port even more.  I am also happy that a lot of the upstream glibc work has
been going on to move arch specific parts to generic code, I think you are
making great progress.

In my view the changes need to be upstream before the patch can go into 
glibc.  We want to avoid the mess we had with MicroBlaze where the port 
turned out to depend on GCC patches that hadn't yet been upstreamed.

Notes,  I don't think that will be a problem.  Binutils patches are already
upstream.  The GCC patches should be too before I send the V2 series (I just
need to push them).
