The softfp is explicit disabled, so I think checking it on code does
not add much. Once softfp is actually enabled we can add it back, it
also make is explicit in history what was required to enable the abi.

From previous discussion, R_LARCH_NONE dynamic relocations should be
considered missing optimization (assuming input unrecognizable
relocations are handled in static linker). Since not handling it on
bootstrap generates unusable loader, I think it would be better to
handle on for RTLD_BOOTSTRAP.

This file is not required and and the idea is to eventually remove
it [1]. The default definitions already add the expected loader
and libc names, so SYSDEP_KNOWN_INTERPRETER_NAMES and
SYSDEP_KNOWN_LIBRARY_NAMES are redundant.

The softfp is explicit disabled, so I think checking it on code does
not add much. Once softfp is actually enabled we can add it back, it
also make is explicit in history what was required to enable the abi.
*Fixed all by removing **__loongarch_soft_float.*

From previous discussion, R_LARCH_NONE dynamic relocations should be
considered missing optimization (assuming input unrecognizable
relocations are handled in static linker). Since not handling it on
bootstrap generates unusable loader, I think it would be better to
handle on for RTLD_BOOTSTRAP.
*

*Fixed.*

This file is not required and and the idea is to eventually remove
it [1]. The default definitions already add the expected loader
and libc names, so SYSDEP_KNOWN_INTERPRETER_NAMES and
SYSDEP_KNOWN_LIBRARY_NAMES are redundant.

*loongarch/ldconfig.h removed.*

It does not have the case of !__HAVE_64B_ATOMICS, but since only 64-bit
is support I don think this will be troublesome. Also, the idea is to
remove such atomic macros on next release.

This is used solely if the architecture defines USE_IFUNC_GETTIMEOFDAY,
which requires IFUNC support and an arch-specific gettimeofday.c.
If I understand correctly iFUNC is not really fully supported or has
some issues (due the wrong relocation placement in the plt section).
So I think it wold be better to just remove it on enabled in a future
optimization.

Why havent't you enable pointer mangling? It is used to add some hardening on
some internal usage (for instance atexit functions).

Both __gregs and __pc are a unsigned long lont, I think it would be better
to use uintptr_t here.

Use 'long int' here.

Move the long int i to define within the loop definition.

I suggest to use "__loongarch_lp64" for checking ABI grlen. Consider:
"gcc -march=la464 -mabi=ilp32d ..."
Once ILP32 ABIs are available, will __loongarch_grlen be 64 or 32 in
this case, where the hardware has 64-bit registers but the ABI uses them
as 32-bit? Our documentation is not clear about this question and
currently we understand __loongarch_grlen as hardware GR length instead
of the register length used in ABI [1].
[1]:https://github.com/loongson/LoongArch-Documentation/pull/28#discussion_r917364055
OTOH if you think "we should define __loongarch_grlen as the register
length for ABI, irrelevant to the hardware", you need to inform your
colleagues to clarify it in the doc.

To my intuition it's the hardware GRLEN, but thinking about it harder,
there is indeed ambiguity. Some clarification would be useful here.
(BTW, Yinyu, could you keep me CC-ed when sending your next revisions?
I'd like to take a quick review to ensure there are as few historical
warts as possible when the patchset get updated.)

There are too much changes in this branch. Could you isolate a minimal
binutils patch enough for eliminating R_LARCH_NONE and R_LARCH_IRELATIVE
from .rela.plt, get it reviewed, and push it into GNU binutils repo? I
don't think it's a good idea to make *GNU* libc depend on some external
linker code which is not reviewed by GNU binutils developers.
And we need to do this ASAP: we already missed binutils 2.39 release
branch cut date [1] and if we don't move fast we'll miss glibc-2.36
release date.

I finished my review for the port and it looks ok in general, however there
some pieces that would require a v7:
1. Add R_LARCH_NONE handling on bootstrap, binutils 2.38 does generated it
and from previous discussion it should be considered a missed
optimizations instead of a linker error.
2. Remove the __loongarch_soft_float parts, since there is no support for
soft floating-point.
3. Remove sysdeps/unix/sysv/linux/loongarch/ldconfig.h, this file is not
required.
4. Some minor style issues.
5. Either remove HAVE_GETTIMEOFDAY_VSYSCALL or add a gettimeofday ifunc
optimization.
The only part really prevent port inclusion is 1. I am also assuming ifunc
is support (at least you have added support on the Linux ABI part) with
binutils 2.38. If not, you will need to remove support until you fix it on
binutils.
And also, you need to check and report the test results using the expected
defined release branches, using out-of-tree branches are not acceptable for
inclusion.

The series tested with Linux-5.19-rc4, Binutils-2.38, and GCC-12.1.
Some kernel patches used but they are only boot protocols and hardware
drivers, not related to userspace ABI so Glibc should be unaffected.
Some Binutils and GCC patches used but they are all already committed to
upstream.
To work around binutils issues, I added R_LARCH_NONE back to
RTLD_BOOTSTRAP, and disabled IFUNC (by adding
libc_cv_ld_gnu_indirect_function=no into preconfigure).

Thanks.

I do not think this is blocker, but if you need to explicit add
libc_cv_ld_gnu_indirect_function=no it means your toolchain can potentially
generate invalid binaries:
$ cat test.c
#include <stdio.h>
static int impl (void) { return 42; }
static void * resolver (void) { return impl; }
int ifunc (void) __attribute__((ifunc ("resolver")));
int main (int argc, char *argv[])
{
printf ("%d\n", (int) ifunc ());
return 0;
}
$ loongarch64-linux-gnu-hard/bin/loongarch64-glibc-linux-gnu-gcc test.c -o test
$ qemu-loongarch64 elf/ld.so --library-path . ./test
./test: error while loading shared libraries: unexpected PLT reloc type 0x0c
It would be better if you just disable ifunc support on static linker for now.

> Hello, these are LoongArch patches v6, and we really need your futher suggestions:
The v6 patches came up for review in the weekly Monday patch review meeting.
May you please post a v7 with all suggestions integrated?
Having a new v7 would help with review and inclusion into the release.
Thank you!
