Hello, the answers are as follows, and we really need your futher suggestions:
LoongArch patches v1: https://sourceware.org/pipermail/libc-alpha/2021-August/130262.html
1. Is there ABI documentation for the function-calling ABI? The ELF ABI
document you link to says essentially nothing about that.
LoongArch-Doc: https://github.com/loongson/LoongArch-Documentation
We add new section: procedure calling convention.
https://loongson.github.io/LoongArch-Documentation/LoongArch-ELF-ABI-EN.html#_procedure_calling_convention
2. Please provide details of the test results for the port with the glibc
testsuite and the binutils / GCC / Linux kernel ports as submitted
upstream (the exact versions of those components proposed for upstream,
not some other version). You might need to work around some of the issues
currently present building glibc with GCC mainline; if so, please state
the exact patches you are using for that workaround on top of the proposed
port version (you might need to use
<https://sourceware.org/pipermail/libc-alpha/2021-August/130244.html>, for
example). It's required that the compilation parts of the testsuite must
have fully clean results. For any test failures in the rest of the
testsuite, make the .out and .test-result files available, along with any
analysis you have done of why those tests are failing.

===================================================================
3. I see there's an upstream submission (not yet committed upstream) of
QEMU support for LoongArch, could you describe the status of that? (See
"There is no requirement for a CPU simulator (free software, e.g. QEMU, or
otherwise) to be available, but if one is available, it is useful to
mention in the summary message (along with any information on available OS
etc. that might help people set up an environment for testing things about
the port)." on the NewPorts page.)
We are donating machine to the GCC Compile Farm Project
4. What ABIs are supported for the port? You mention 32-bit doesn't work
(so it would be best to remove that code until it's ready), so only 64-bit
ABIs are supported. Is a soft-float ABI supported, or only hard-float?
You have __loongarch_soft_float or __loongarch_hard_float conditionals in
some places, but other things suggest only hard float is supported (the
lack of any with_fp_cond definition in your preconfigure fragment, in
particular). Apart from conventional 32-bit and 64-bit ABIs, there's the
question of whether you have or intend to have an ILP32 ABI that uses
64-bit registers and the 64-bit instruction set (like x32 for x86_64);
there's no need to have such an ABI, but if you do plan to have one, you
need to be very careful about what you mean when you say "32-bit" or
"64-bit", to make it clear whether such an ILP32 ABI is included or not.
add loongarch 5. There needs to be at least one entry added to build-many-glibcs.py for
each ABI supported by the port.
Now we only support 64-bit hard-float ABI.
6. You're making local changes to config.sub and config.guess. Don't do
that; the latest versions from config.git should be imported instead, with
no local changes, outside of the patch series adding the port.
corrected
7. This patch series is missing NEWS and README updates.
corrected
8. We don't use "Contributed by" any more in new source files. You can
put such information in the NEWS entry for the addition of the port, and
in contrib.texi (the latter listing relevant individuals, not companies),
instead.
corrected
9. Note that new source files should have a one-line description above the
copyright notice.
corrected
10. Note the need for a manual/math.texi update in the list of
configurations supporting _Float128.
not support yet
11. Florian has already noted that GLIBC_2.35 should be the minimum ABI
version for the port. This has other implications beyond the DEFAULT
setting in shlib-versions. You're adding some entries to
sysdeps/unix/sysv/linux/loongarch/Versions with old symbol versions; those
should not be present (some of the GLIBC_2.0 entries are for libgcc
functions only relevant for extremely old glibc ports). If you need any
Versions entries at all, they should be either GLIBC_PRIVATE or
GLIBC_2.35, and you should be able to give an explicit justification for
why such an entry is needed (i.e. the function would not be exported at
all without the entry, and either is part of the architecture-independent
glibc API, or is needed as an architecture-specific function or a
GLIBC_PRIVATE function).
corrected
12. For each ABI supported by the port (see point 4 above) you need a
unique dynamic linker name (not used by any existing ABI listed at
<https://sourceware.org/glibc/wiki/ABIList>; probably mentioning the
architecture name somewhere in the dynamic linker name), as specified with
ld= in shlib-versions. You have an ldd_rewrite_script setting that only
makes sense with such names (and only makes sense when multiple ABIs are
supported in the same root filesystem, see
<https://sourceware.org/legacy-ml/libc-alpas specified with
ld= in shlib-versionsha/2018-01/msg00008.html> for
more details of what's needed for such support), but I don't see anything
to actually implement such names. Note the need for the dynamic linker
names to be consistent in GCC and glibc.
corrected
13. arch_minimum_kernel should be set to 10.0.0 until the actual upstream
kernel version that gets the port is known, and then to the actual
upstream version (so 5.14.0 or later). Accordingly, kernel-features.h
should not have any "before 4.20" conditionals in it (so you don't need an
architecture-specific kernel-features.h at all).
corrected
14. Regarding the optimized functions in patches 12 to 14, see the last
point on the NewPorts page regarding considering carefully (possibly with
benchmarking) whether such functions are actually beneficial compared to
the current generic C versions - and, if beneficial compared to the
current generic C versions, whether helping to get the improved generic
functions linked from that page into glibc would avoid the need for some
or all of the architecture-specific implementations.
optimized function string/memset/memcpy/memmove/sinf/cosf removed

This patch contains the miscellaneous math routines and headers we have
implemented for LoongArch. This includes things from <math.h> that aren't
completely ISA-generic, floating-point bit manipulation, and soft-fp
hooks.

If IFUNC isn't supported, the configure test
(libc_cv_ld_gnu_indirect_function) should fail, have-ifunc should be no
and elf/Makefile should disable the tests.
Those failures suggest you have partial support in the toolchain - enough
binutils support for the tests to be enabled - but are either missing
glibc support, or some of the toolchain support is broken. In that case,
you should fix/add the broken/missing support so that the tests pass. (Or
if it's wrong that the libc_cv_ld_gnu_indirect_function test passes at
all, maybe that's a binutils bug and you need to fix the binutils port so
that that configure test fails.)

So that issue needs fixing in GCC upstream.

It's supported by the port (with the same ABI as long double, via the
ieee754/ldbl-128 inclusion in sysdeps/loongarch/Implies) - the functions
are in the ABI test baselines. So you need to update math.texi to reflect
that.

You have arch_minimum_kernel=5.15.0, but the support isn't in 5.15.0, and
indeed isn't in Linus's git tree for 5.16 either.
Once it's in Linus's git tree, you can set arch_minimum_kernel to the
actual version that will have the port. Until then, you should use 10.0.0
as a placeholder.

The constants here look like those in bits/mman-map-flags-generic.h.
I.e., you shouldn't need this header at all; the default
architecture-independent version should suffice.

You shouldn't have this library at all, since Adhemerval's recent commit,
so shouldn't have an ABI test baseline for it.

Likewise, there should be no libdl for a new port.

Likewise, since --enable-obsolete-nsl was removed. This shows up an issue
with the OpenRISC port submission, which shouldn't have libnsl.abilist
either.

Likewise, there should be no libutil for a new port.

Set up a math-use-builtins-sqrt.h header for LoongArch and ensure that
your GCC port can expand __builtin_sqrt and __builtin_sqrtf inline, and
then you shouldn't need these files because the generic files with their
USE_SQRTF_BUILTIN and USE_SQRT_BUILTIN conditionals will suffice instead.

If the target does not support ifunc, why libc_cv_ld_gnu_indirect_function is being
set then? I think you will need to disable the usage of %gnu_indirect_function
on static linker.

Is this being tracked by a GCC bug report? We need to understand if we
require to use math_force_eval to avoid such issue on other ports as
well.

Please follow other ports description, such the recent one for or1k [1],
by adding the minimum binutils, gcc, and Linux version required along
with the triple name and any other relevant information (32/64-bit,
endianess, time_t, LFS support, etc).
Also put the addition at the end of the list.

You stated you only supported 64-bit ABI and it should imply in wordsize-64,
so why do you need to provide an arch-specific wordsize.h?

Why do you need to add it? It is used solely on unwind code used only for
compat code on old ABIs.

Do you plan to support multilib with different ABIs in the same system? Otherwise
I think adding another SYSDEP_KNOWN_INTERPRETER_NAMES does not add much.

Use libm_alias_finite, the finite alias are deprecated and only provided
as compat symbols.
This is being replicated already on aarch64 and mips64, maybe we could
add on a generic folder and use it instead.

Why can't you use the generic definition? Also, I think all the __loongarch_lp64
tests to avoid 32-bit build should be moved to a configure test instead.

This file has been refactore by e4e11b1dba261cb650e6 (2.32), now ports that
deviate from Linux generic ABI should provide a signum-arch.h header. And
this seems not to be the case here.

Why can't you use the generic sysdeps/unix/sysv/linux/ipc_priv.h here?
I woudl asusme that LoongArch will have __ASSUME_SYSVIPC_DEFAULT_IPC_64
defined and thus __IPC_64 will be 0x0.

Do you really need 7 arguments for syscall? Otherwise you should use the generic
interface.

Why can't you use the generic Linux sysdeps/nptl/bits/struct_rwlock.h ?

This file should not be required, Florian has refactored it to avoid this
boilerplate code (check bdc90abc48f0528588600df37eebdc04ce01b2f0 and

So is the idea to evetually support ILP32 as well? My understanding it
is not currently supported, so I think it should not be handled it
yet.

We have sysdeps/ieee754/soft-fp/ for something similar, but that's only
intended to be used via Implies in cases where software floating point
with no exceptions / rounding modes support is in use and so the generic
round-to-odd function implementations would be incorrect.
However, particular functions in that directory can be used via #include
from elsewhere in sysdeps if appropriate - whether because of the lack of
another generic implementation to use (as in the case of ldbl-128 sqrtl)
or because it's more efficient (see how sysdeps/mips/ieee754/s_fmal.c
includes sysdeps/ieee754/soft-fp/s_fmal.c because long double is always
implemented in software for MIPS64). So you could add sqrtl to that
directory then #include it from individual architectures. Or you could
have e.g. ldbl-128-soft-fp that can go in sysdeps when appropriate, with
the option to use it also for cases like MIPS fmal where the soft-fp
implementation is more efficient than using the ldbl-128 version when all
the underlying arithmetic operations used are themselves soft-fp
operations.
