I think there should be a sotruss-lib.c file for this port.
I don't see a get-rounding-mode.h file here, as I would expect to be
needed given recent changes.
You also need to update the patch for the recent change

Normally such files would be in the fpu/ directory. (ARM is a special
case because of the runtime detection of whether an FPU is present, but I
don't see such an issue here.)

None of these tst-backtrace*.c files exist in glibc, so these CFLAGS
definitions should not be present.

Such a conditional only makes sense if you are providing a .S version of
____longjmp_chk. But you don't seem to be doing so; instead you're using
the generic C version, complete with a helper macro in jmpbuf-offsets.h.

GCC 4.7 and later have __atomic_* intrinsics with better control over
barrier semantics. Since you can assume a GCC version with that support
for AArch64, you should use __atomic_* instead of the legacy __sync_*.

Until we've worked out the right way to fix bug 3439, so that the values
remain in debug info as well as being usable in #if, please follow the
same approach as in other versions of this header to defining these
values; all architectures can then be fixed at once to conform to ISO C
when bug 3439 is fixed.

The names "fpcr" and "fpsr" are in the user's namespace; you need to use
__fpcr and __fpsr here, as this is an installed header.

Does the AArch64 architecture define that fma instructions are always
available? If so, you can just define FP_FAST_FMA and FP_FAST_FMAF
unconditionally (and FP_FAST_FMAL never). Certainly a comment referring
to GCC 4.6 is inappropriate, since such a version doesn't exist for
AArch64.

It's now obsolete for ports to define their own ADDRIDX, VALIDX or
VERSYMIDX macros, so remove this macro definition.

This file appears out of date (e.g. no ulps listed for the clog tests I
recently added).

If you have any ulps for sqrt, something is wrong. Maybe this file is
*very* out of date and was generated before my patch

Missing FP_TRAPPING_EXCEPTIONS. You should check all your files for any
relevant changes to glibc since whenever you started the port....
> +aarch64.*-.*-linux.* DEFAULT GLIBC_2.16
Use GLIBC_2.17, since this port wasn't in 2.16.
> +#define PLTJMP(_x) _x
As far as I can see, PLTJMP is only used in architecture-specific .S files
(and other macros for use in such files), for a few architectures. If an
architecture has a null definition of it, there's no real point in having
the macro existing at all - so I advise removing it, and all calls to it
in AArch64 code. Please check other internal macros to make sure there is
actually some point to defining them.

I see no mention of "cantunwind" in start.S or elsewhere in the patch
except here. This looks like a relic of ARM EH, irrelevant to AArch64,
which should be removed.

Why is this needed? If it's needed for some AArch64-specific reason,
please add comments to explain. If the issue is more generic, but latent
on other platforms, send a patch to libc-alpha for a libc makefile with
appropriate rationale. (If there is a reason to need to build these
functions with exceptions enabled, I'd think that need is generic, even if
it only causes issues with the linux-generic versions of them, or
something like that.)

ports/sysdeps/unix/sysv/linux/generic/Makefile has this; you shouldn't
need to duplicate it.

No, please use 3.7.0 here as that's the actual version of the support
going in. Likewise in kernel-features.h.

Apart from updating the baselines to GLIBC_2.17, have you checked that the
set of symbols exported (ignoring versions) agrees with other 64-bit
platforms to the extent expected - that there's nothing accidentally
missing?

Why do you need this file rather than one of the generic versions - how
does this differ from what's used for other linux-generic architectures?
> diff -x .git -uNr glibc.orig/ports/sysdeps/unix/sysv/linux/aarch64/syscalls.list glibc/ports/sysdeps/unix/sysv/linux/aarch64/syscalls.list
Why do you need this file? It looks rather like it duplicates
ports/sysdeps/unix/sysv/linux/generic/syscalls.list, and any entries that
do duplicate that file should be avoided.

Not OK. Get the kernel to define the set of syscall macros you want, and
not to define any syscalls that aren't actually wanted. No such #undef
should need to be present for a port that is new in both kernel and glibc
like this.

Likewise, such conditionals should not be needed. With 3.7 as minimum
kernel version we should know what syscalls the kernel defines in its
headers.

Folks,
This revised patch addresses the comments raised by Carlos, Andreas
and Joseph on the original aarch64 port submission.
The main changes since from the original patch are:
* Copyright years have been merged inline with the documentation
Carlos highlighted.
* ARCH_PLTEXIT_MEMBERS prototype corrected.
* pthread_spin_lock and pthread_spin_trylock switched to generic versions.
* The port has been rebased over the tree as of 1/11/2012, this brings
in a number of the changes highlighted as missing by Joseph.
* ADDRIDX, VALIDX and VERSYMIDX definitions removed.
* Added sotruss-lib.c
* Added get-rounding-mode.h
* Refactor around recent clean up of init-first.c
* Refactor around recent cleanup of fcntl.h
* libm-test-ulps regenerated, bringing in clog definitions and setting
sqrt ulps to 0.
* Relocated FPU support to fpu/ directory.
* Remove CFLAGS-tst-backtrace* cruft.
* Remove CHECK_SP cruft.
* FE_INVALID and friends defined using the same mechanism adopted in
other ports.
* fenv_t members renamed to avoid namespace pollution
* FP_FAST_FMA and FP_FAST_FMAF hardwired on.
* FP_TRAPPING_EXCEPTIONS defined
* Default version moved to GLIBC_2.17
* Minimum kernel version moved to 3.7.0
* Assorted port specific macros removed.
* Switch to generic not-cancel.h
* Switch to generic syscalls.list
* Removed #undef NR_* cruft.
* Duplicate Makefile entry for epoll_create and friend removed.
The -fexception CFLAGS change has been removed and posted to
libc-alpha independently.
Joseph's review pointed out that the port should switch from __sync to
__atomic primitives, work on this is in progress, but not included in
this patch.
The test suite has been run cross, we have the following outstanding
issues that need further investigation:
* test-ldouble.out
27 instances of underflow set. These all appear to be related to
scalbn setting underflow when not expected.
* test-double.out
38 instances of underflow not set on fma related tests.
* test-ildoubl.out
3 errors for ULPs on csqrt tests.
Updated ChangeLog attached.
Thanks
/Marcus

This is a lot closer to being ready, but there are still some issues to
address:
Did you check the set of exported symbols against other 64-bit platforms
as I suggested? I note, for example, that you're missing an
__sqrtl_finite symbol in libm.

With that done, "Free Software Foundation, Inc." can now always go on the
same line as the "Copyright (C) <years>"; it was only long lists of years
that required having it sometimes on a separate line.

You still have sqrt ulps listed. That still suggests something is wrong
(either not removing the old ulps properly before regenerating, or an
actual problem with sqrtl).

Now that I've fixed bug 3439, this will need another update to follow the
new mechanism now used for these macros.
(Depending on the order in which the patches go in, one of the other of us
will also need to do an fclrexcpt.c update in line with my patch
<http://sourceware.org/ml/libc-alpha/2012-11/msg00057.html>.)

That really shouldn't be a hard conversion.

Since you've removed the optimized functions so they can be dealt with
after the main port is in, you'll be using
sysdeps/ieee754/ldbl-128/s_fma.c (which is generally unlikely to be a good
idea, except on any systems implementing binary128 floating-point in
hardware - most architectures using ldbl-128 in software make sure to
override the choice of fma implementation, with the dbl-64 version if they
don't have hardware fma).
While the optimized fma using fma instructions would no doubt fix those
failures, they do suggest you have a bug in your sfp-machine.h - either it
isn't setting INEXACT exceptions correctly from the addition, so
fetestexcept fails to detect them, or it isn't handling underflow
correctly on conversion to double, or both. So if you investigate these
failures before adding optimized fma, they may also solve some of your
test-ldouble failures as well.

However, it's possible that even with a fully correct soft-fp port there
might be failures for these tests (that is, that there are currently
unfixed bugs relating to ldbl-128 and shown by the testsuite) - I don't
know whether these tests have clean results for other ldbl-128
architectures right now or not.

Missing const - should have type "const fenv_t *". I just added conform/
baselines for fenv.h which would detect such a type error. Unfortunately
(a) conform/ doesn't yet support cross-testing and (b) it would be
necessary to compare results between architectures to detect any
AArch64-specific problems it shows up, since the expected results aren't
yet very clean. So it may be premature to try to identify header problems
that way.

Thanks for the review, Ive looked into a couple of the FP issues and
would appreciate your thoughts on the following....

The first couple of failures we have in test-double.out are:
Failure: fma (min_value, min_value, +0) == +0: Exception "Underflow" not set
Failure: fma (min_value, min_value, -0) == +0: Exception "Underflow" not set
The addition cannot result in an UNDERFLOW, which suggests that
truncation is not correctly detecting the UNDERFLOW.
Digging into the behaviour of trunctfdf2 (provided by libgcc) on the
value LDBL_MIN, I expected to see INEXACT and UNDERFLOW but only get
INEXACT.
The FP_TRUNC() macro detects the situation where the result exponent
is too small and zero's the result fractional bits, explicitly setting
the least significant working bit:
op-common.h:
1223 if (D##_e < 1 - _FP_FRACBITS_##dfs)
\
1224 {
\
1225 _FP_FRAC_SET_##swc(S, _FP_ZEROFRAC_##swc);
\
1226 _FP_FRAC_LOW_##swc(S) |= 1;
\
1227 }
Subsequently FP_ROUND() detects the non zero working bits and raises
INEXACT before applying 'round to nearest'. After rounding the working
bits are 0x5. The logic in _FP_PACKSEMIRAW() shifts out the working
bits leaving 0 in the fractional bits. The detection of underflow
fails because the fractional bits are now all zero.
145 _FP_FRAC_SRL_##wc(X, _FP_WORKBITS); \
146 if (!_FP_EXP_NORMAL(fs, wc, X) && !_FP_FRAC_ZEROP_##wc(X)) \
147 { \
148 if (X##_e == 0) \
149 FP_SET_EXCEPTION(FP_EX_UNDERFLOW); \
The logic in FP_TRUNC highlighted above that sets the least
significant working bit makes the detection of underflow dependent on
rounding mode. Is this intentional?
Any insight into this welcome.
Thanks

I'm looking at the current soft-fp code in glibc rather than the older
version in libgcc (which will need updating from glibc once this issue is
resolved [*]) but don't see any relevant differences.
There are two places in op-common.h handling underflow, _FP_PACK_SEMIRAW
and _FP_PACK_CANONICAL.
Looking first at the latter (not the one involved in the present issue),
it seems OK on the basis of tininess-before-rounding.
(Tininess-after-rounding would need extra work. 32-bit ARM is
tininess-before-rounding, so I'll guess that AArch64 is as well.) That
is, it will raise the underflow flag for all inexact underflow cases,
including underflow to zero.
For the former, there are two issues with the underflow handling: it's
determined based on the exponent after rounding (which is not correct for
either "before rounding" or "after rounding" tininess detection - "after
rounding" tininess detection means after rounding to the normal precision
rather than after rounding to an actual representable value), and it has
the test you note for whether the mantissa, after shifting, is nonzero. I
think the correct thing to do would be to have a test "if (X##_e == 0 &&
!_FP_FRAC_ZEROP_##wc(X))" (which then has the existing exception-setting
logic) immediately after the _FP_ROUND call. That way, (a) the logic is
before-rounding tininess, which at least is consistent with
_FP_PACK_CANONICAL, (b) the INEXACT exception has been set by _FP_ROUND if
applicable, as required for the logic determining whether to raise the
underflow flag and (c) the low bits haven't yet been shifted out, so an
exact zero can be distinguished from an inexact one by the mantissa.
The code that now has "if (!_FP_EXP_NORMAL(fs, wc, X) &&
!_FP_FRAC_ZEROP_##wc(X))" might then better test "(X##_e ==
_FP_EXPMAX_##fs && !_FP_FRAC_ZEROP_##wc(X))" (i.e., the value is a NaN,
the only remaining case there).
After-rounding tininess detection would be more complicated, but as I note
above it's probably irrelevant to AArch64 (though relevant to complete
correctness for Alpha and MIPS, and for the use of soft-fp for __float128
in libgcc for x86 / x86_64 / IA64).
[*] See what I said in
<http://gcc.gnu.org/ml/gcc-patches/2012-10/msg02963.html> regarding asking
architecture maintainers to help provide FP_TRAPPING_EXCEPTIONS
definitions after such an update.

This resolves the majority of the outstanding issues. The solution
above is not quite sufficient because given a true 0, FP_ROUND may set
working bits resulting in the underflow test failing. I resolved this
by adjusting FP_ROUND such that it does not attempt to round a true
zero, is that sane? I've attached my current patch. The patch is
against glibc/soft-fp but I've actually be using it applied to
libgcc/soft-fp. What is the recommend way to test patches to soft-fp
in glibc?

I think it would be better to put all the rounding logic inside the
existing "if (_FP_FRAC_LOW_##wc(X) & 7)" conditional that determines
whether to set the INEXACT exception - if none of the low three bits is
set, there's no point in doing anything for rounding.
soft-fp patches should go to libc-alpha. (Once checked in, the patch to
update all the soft-fp files in libgcc from their soft-fp versions goes to
gcc-patches, of course.)

You could ask the architecture maintainer of an architecture that uses
soft-fp in glibc (e.g. SPARC) to test it, though I think testing in libgcc
is just as useful.

Re-sending. No bounce received, perhaps some of my google email is
being treated as spam? I''ve compressed the patch on the off chance
that the original was dropped because of its size, but I would have
expected a bounce message if that was the case.

Of these, the csqrt ones seem AArch64-specific, so you should continue to
investigate them (I don't know if they are bug in the port, or a bug in
generic code that for some reason only shows up with this port). The
others (spurious underflows from clog10, clog, yn) appear to be generic to
ldbl-128 architectures (they appear in the list for S/390 that Andreas
Krebbel posted at
<http://sourceware.org/ml/libc-alpha/2012-11/txt00003.txt>, for example) -
so while I hope someone will investigate them for 2.17, they don't
indicate anything wrong with your port in particular.
> Revised patch and ChangeLog attached.
This is OK with the following changes:
* Add lll_futex_timed_wait_bitset to lowlevellock.h, as recently added in
libc.
* Remove the definitions of __NR_pread and __NR_pwrite in sysdep.h
(sysdeps/unix/sysv/linux/generic/sysdep.h already has them, so you
shouldn't need to duplicate them; just make sure that file gets used at
some level among sysdep.h files including each other).
You should also list yourself as AArch64 maintainer at
<http://sourceware.org/glibc/wiki/MAINTAINERS>.
I believe you still need to continue working on getting the following into
libc for this port to be fully functional:
* The soft-fp change for correct underflow handling (GCC's soft-fp will
then need updating), revised as I suggested then will need posting to
libc-alpha.
* The -fexceptions makefile patch, where you need to answer HJ's question
and follow up as needed on getting this patch in.
(As well as investigating those csqrt ulps further. And once the main
port is in and the above issues are resolved, you may of course wish to
work on getting in the optimized functions that were in the original
patch.)

Don't forget that the linux kernel has another copy of soft-fp, used for
kernel fp emulation in some architectures. Fixes ought to be propagated
there as well.

This is about a patch to _FP_PACK_SEMIRAW (and supporting changes
elsewhere). The kernel's version of soft-fp diverged from glibc before I
added the "semiraw" optimizations in 2006 - anyone wishing to merge in
this fix will need to merge in several years' changes from the glibc code
first.

Great!
I think this deserves a mention in the NEWS file, could you write
something, please?
