Hi,

v2 of glibc port to ARC processors from Synopsys.

Thx for reviewing the v1 [1], I've hopefully addressed all the comments.
Any unlikely omissions are unintended.

Also apologies for the bad timing given the imminent release, but that ship
has likely already sailed, so we might as well continue our march independently.

The main changes since v1 are

  * sigaction updates
    - drop sigaction.h, use generic version
    - sigaction.c to use generic linux/sigaction.c
    - arch specific __sigset_t.h to enable __sigset_t [2] vs. [128]

  * atomics: Enable USE_ATOMIC_COMPILER_BUILTINS
  * switch to init_array, removed crt{i,n}
  * Build: remove libc_cv_fpie=no
  * __startcontext: use cfi_undefined to terminate unwinder

  * dropped ldconfig.h, libnsl.abilist, cacheflush.c (use syscalls.list),
    procfs-id.h, math_private.h

  * cosmetics
    - Trying to follow the coding style and conventions
    - Folded the testsuite fixes patches into main port patches
    - Update copyright headers to 2019

Customary test results: Built against
   binutils-2_32-branch
   gcc-8-stable (commit 0d5ba57508c5 as of today with prerequisite backport)

(a) build-many-glibcs.py

| Summary of test results:
|   1173 PASS		# same as v1
|     15 XFAIL		# same as v1
|
| PASS: glibcs-arc-linux-gnu check

(b) Full testsuite ran in a cross compile setup using buildroot on HSDK development
    platform. Full log at [2].

| Summary of test results:
|     22 FAIL		#  2 fewer than v1
|   5151 PASS		# 27 more than v1
|     23 UNSUPPORTED	#  4 fewer
|     19 XFAIL		# no change

In the absence of clear consensus regarding consideration of new ports to 
undocumented architectures (which would need to result in consensus on 
suitable rules on the subject to go in 
<https://sourceware.org/glibc/wiki/NewPorts>), and in the absence of 
suitable public architecture and ABI documentation, I don't intend to 
attempt review of this or subsequent versions of the port submission.  (I 
am supposing that the documentation available at 
<http://me.bios.io/ARC_disassembly> - which in any case does not include 
an ABI reference - is for an architecture version too old to be sufficient 
for understanding and maintaining the port code as may be needed in the 
course of glibc maintenance.)

New ports should use the preferred values for these macros.

OK, changed to 0 and 0 per commit 06be6368da16104 ("nptl: Define
__PTHREAD_MUTEX_{NUSERS_AFTER_KIND,USE_UNION}")

That would be really unfortunate. Your prior reviews of RFC and v1 have been
immensely helpful, it would be a shame to not continue to get this privilege goinf
fwd.

Having said that, wheels were already set in motion after your initial request in
December. The ARCv2 ABI spec was opened up quickly (and mea culpa for not
referencing it v2 submission). It is now publicly accessibly at [1]

The public version of PRM is being worked on, but it will take time to come to
fruition. I hope you appreciate these things take time, considering where we came
from - and it seems you found a workaround anyways ;-)

Not really. It sure pertains to the predecessor ARCompact ISA, but in ARCv2 the
bulk of changes were to Interrupt architecture, micro-architecture optimizations,
SMP support etc, which are not relevant for glibc or general userspace coding.
While the encodings etc did change, much of the baseline instruction set is pretty
much the same, so ARCv2 assembly or generated code easily maps to ARCompact.

I do hope this is enough for you to reconsider reviewing the code.

Thx,
-Vineet

This seems like something that could be a common issue for new ports, so 
worth a mention at <https://sourceware.org/glibc/wiki/NewPorts> alongside 
such things as using init_array and USE_ATOMIC_COMPILER_BUILTINS.

Thanks.  To be clear, the description at 
<https://sourceware.org/glibc/wiki/NewPorts> of what should go in the 
summary message for a new port submission should be considered to apply to 
every version of that submission, so that each submission is 
self-contained.  That is, every version of the submission should include 
information such as pointers to relevant manuals (in addition to 
whatever's appropriate about changes from the previous version of the 
submission).

There are five months until the freeze for 2.30 starts (obviously the port 
will need its symbol versions updated for 2.30).

Now it's saying those macros are in atomic-machine.h.  That's not right; 
the information about those macros needs to go in a separate paragraph.

So this required a bunch of tricking changes to _SIZEOF_PTHREAD_*.

However what was not obvious is adjustment to
sysdeps/<arch>/nptl/pthread-offsets.h to __PTHREAD_MUTEX_*_OFFSET. But these don't
seem to be *actually* used anywhere. Sure there are assert checks in
pthread_mutext_init.c but what's the point: the struct is generic anyways. IOW I'm
not sure what port specific errors/inconsistency they are catching, other than the
fact that they need to be hand calculating when starting a new port.

Am I missing something ?

The _OFFSET macros are for ensuring binary compatibility.

The public PRM is now available and I would like you to try and access it so that
any bureaucracy is out of the way before I re-post ARC port for 2.32 !

Do note you still need to register to download but that is no different than say ARM.

The landing page is
https://www.synopsys.com/dw/ipdir.php?ds=arc-hs44-hs46-hs48

And there in the link to actual doc is
https://www.synopsys.com/dw/doc.php/ds/cc/programmers-reference-manual-ARC-HS.pdf

Let me know how it goes.

Thx,
-Vineet

Thanks!

There was one technical point regarding the glibc port I raised briefly in 
a discussion at the end of the Cauldron in Montreal: you should consider 
whether it would make sense, as a new 32-bit port, to have 64-bit times 
and 64-bit off_t, ino_t, etc. from the start, as RV32 is doing.  We don't 
have a specific policy for this, but it may make sense for new ports not 
to include ABI variants that either are, or will become, obsolescent.  If 
you require Linux 5.1 or later for the port then all or nearly all the 
architecture-independent pieces required for a 32-bit port supporting only 
64-bit times should be covered by the RV32 patches, which I think are 
quite close to being ready to go into glibc, though you'd need to watch 
out for any (new or existing) #ifdef conditionals that might try to use 
32-bit-time syscalls if they exist (which they don't on RV32) - and that 
would not prevent supporting older kernel versions later if desired, as 
the Y2038 support gets built out (including, in particular, the support 
for falling back to 32-bit-time syscalls in functions for 64-bit-time 
interfaces).

I agree we should do that.

Ok I see patches in flight on the mailing list. Would it make sense for me to
start off in parallel with ARC port which will take it's due course of review and
rework and in that process upstream y2038 work settles down and I then
rebase/switch ARC to that. Or would rather wait for upstream to settle down and
then I adjust/post ?

Thx,

I'd suggest posting patches that are on top of the RV32 ones (maybe 
there's a git tree with RV32 changes to current glibc that could be used), 
and that only support Linux 5.1 and later (so you don't need anything much 
of the Y2038 support beyond what's in the RV32 patches).

Go for it!

My working branch is here:
https://github.com/alistair23/glibc/tree/alistair/rv32.next

My latest RFC branch is here:
https://github.com/alistair23/glibc/tree/alistair/rv32.rfc6

Thx a bunch Alistair. I'm rebasing my stuff on top of your next branch as it seems
to have more time/y2038 code so will help shake it out as well.

Thx,

If it may help a bit, please also review/check the current status of
Y2038 work.

Some Y2038 related work (mostly for ARM32) may be also helpful as well
(as some patches for RV32 also do the conversion for other
architectures).

https://github.com/lmajewski/y2038_glibc/commits/y2038_edge


Please also find the meta layer for testing Y2038 (with some basic test
suite) code on qemu-arm and Yocto/OE:
https://github.com/lmajewski/meta-y2038

(it shall also be easy to extend this meta layer to add support for ARC
as well).
