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.

This is meant to contain all the LoongArch code that needs to explicitly
name registers or manage in-memory structure layout. This does not
contain any of the Linux-specific code.

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.

There is no need to add this header.

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.

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.

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.

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.

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.

Fixed by using generic definition and __loongarch_lp64 tests have been

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.

As before, I think we should move the LP64 ABI tests to configure time

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.

You shouldn't have this library at all, since Adhemerval's recent commit,
so shouldn't have an ABI test baseline for it.
> diff --git a/sysdeps/unix/sysv/linux/loongarch/lp64/libdl.abilist b/sysdeps/unix/sysv/linux/loongarch/lp64/libdl.abilist
Likewise, there should be no libdl for a new port.
> diff --git a/sysdeps/unix/sysv/linux/loongarch/lp64/libnsl.abilist b/sysdeps/unix/sysv/linux/loongarch/lp64/libnsl.abilist
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.

Fixed by setting up a math-use-builtins-sqrt.h header for LoongArch.

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.

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.
