+
+ This does mean that some code will silently fail to report exceptions,

+ that otherwise wouldn't (such as math/s_fma.c) and so is valuable.
+
+ We intentionally ignore the "exception" arguments of functions that
+ take an exception, since we can't even evaluate the argument
+ without causing a build failure. The extra level of statement
+ expression wrapping avoids "statement with no effect" warnings.

+ success in every case.

Linux-specific code that is required for maintaining ABI compatibility.
This doesn't contain the actual system call interface, that is split out
in order to avoid having a patch that's too big.

My understanding was generic uapi for Linux expects IPC_64 being 0x100 for
newer ports, but seems for recent ones that 0x0 is the expect values. Is
the case or NDS32 is a outlier?

The 'old_kernel_sigaction' is not used anywhere in glibc code and after
sigaction consolidation (b4a5d26d8835d972995f0a0a2f805a8845bafa0b) the
generic Linux kernel_sigactions.h should follow generic uapi. It seems
NDS32 follows this case, so are you sure you need a arch-specific
version?

For new ports of Linux, only new IPC version is supported. Therefore, kernel
does not identify the IPC version by __IPC_64 flag. Unfortunately, kernel also
skip the code for removing __IPC_64 flag from cmd. Therefore, -EINVAL is returned
if __IPC_64 is set. To solve this problem, we set __IPC_64 as 0x0 instead of
0x100.

OK, we will remove it in the next version.
Thanks for your suggestions.

Right, so I think a future cleanup could to define the generic ipc_priv.h to
define __IPC_64 set to 0x0 then. Thanks for the info.

Shouldn't you save them in case you decide to use them for a thread
pointer eventually or something like that?

We do not save $r26, $r27 these two registers because these two register are
reserved for kernel space. In other words, these two registers shall not be used
in user space. Therefore, we needn't save these two registers to jmp_buf.
Thanks for your comment.

Okay, in this case, you could update the register list at the top of the
file. Perhaps also mention the register used for the thread pointer?
Thanks,

In nds32 port, the $r25 register is used for thread pointer. Thanks for your
suggestions. We will update the register list in next version patch.

If that option is needed globally for building glibc, a comment should be
there to explain it.

What does this option do (I don't see it in current GCC)? Since you've
said current GCC versions aren't suitable for building glibc, can't you
just require a compiler supporting the option, unconditionally, so any
test for it is just to ensure a configure error for a too-old compiler
rather than allowing compilation to continue without support?

Ok, I will add the following comment in next version patch.
# For nds32 ABI, the $r15 register, assembler reserved register, is also used to
# storing the syscall number for issuing syscall. In order to ensure the data
# safety, $r15 is included in clobber list by default. Using the option
# -minline-asm-r15 can avoid the conflict between asm-specifier for syscall number
# and clobber list when using inline assembly to issue syscall.

The -mno-scalbn-transfomr is used to disable nds32 specific feature in gcc 6.3.0.
(We put nds32 gcc-6.3.0 in the git repo https://github.com/andestech/gcc.git)
However, this feature will be deprecated in the latest gcc. We plan to disable
this feature by default in gcc-6.3.0 too. Therefore, I will remove this option
from the configure in the next version patch.
Thanks

The clone syscall for fork implementation was consolidate (commit
3dc214977beccc95f0df3b90fa4ca2557fe1bdd2). The new ports need to redefine
it iff the clone kernel ABI does not follow the generic expect one
(check sysdeps/unix/sysv/linux/kernel-features.h:119).

Maybe we could it as a generic version, the only points I am not sure if why
you need a compiler memory barrier here.

The compiler memory barrier is used to ensuring that the input argument has been
stored to the targeted register before issuing syscall in compile time.
Thanks for your suggestions

My understanding is INLINE_SYSCALL_NCS is already issues the syscall with a asm
volatile, so it should prevent any instruction reordering from compiler to mess
with expected kernel register allocation. Are you seeing a miscompile without
the barrier?

I apologize for giving you incorrect information. After I rechecking the git log
of this file, I think this memory barrier is not needed anymore. Originally, we
need to push the 6-th argument to the stack before invoking the system call. In
order to make sure that the value of 6-th argument is correct in stack, we need
a memory barrier which is located between storing 6-th argument to register $r6
and pushing register $r6 to stack. However, the above procedure was not needed
after we modified system call ABI. So, I think the memory barrier is not needed
now. I will remove it in the next version patch.
Thanks for your suggestions.

Please also fix the style issues—syscall should be at the start of the
line, and there should be spaces after the commas, before (, but not
after ( and before ).

It's still useful to have the changes that just add builds for all
relevant ABI or other variants, even if they don't work until those
changes to the other components are upstream, because having the ABI
variants there may help point to other things in the review.
For example: what is the full list of incompatible ABIs supported by this
port that would be listed at <https://sourceware.org/glibc/wiki/ABIList>?
Based on the code in the port, it has at least big-endian and
little-endian variants, so at least two ABIs. Those ABIs should have
different dynamic linker names, as for AArch64 (see my recent comments on
the C-Sky port) - and likewise any other incompatible ABI variants.

But that's been fixed since commit
f2652643d7234c08205b75f527191c2e2b35251f (3 Apr). Are you sure you are
testing relative to a recent git version of glibc?
(The ABI baselines need updating for my change to remove absolute symbols
from ABI baselines, but that change went in two days before your patch
series posting, whereas the RWF_SUPPORTED change went in a month ago.)
As further examples of updates needed to reflect current glibc, patch 8
includes sigcontextinfo.h macros that I globally removed as unused in
commit a44061398c3b531b37e134a6a97accb2251fa28a (22 Mar), while patch 7
includes a readahead implementation, but Adhemerval consolidated those in
commit c57bf7c15ba179168d01f7c6acde7ecbf5dd9cd8 so there shouldn't be any
such architecture-specific implementations needed any more. Patch 5
includes a math_private.h file that shouldn't be needed since my
refactoring in February.

Ok, we will add nds32 port to build-many-glibcs.py and re-name the dynamic linker
based on support ABI in next version patch. In addition, we plan to remove
big-endian support in next patch because we don't have stable platform to
finishing the testing.
By the way, does this port possibly go upstream before the latest nds32 port of
gcc and binutil are upstream?

The testing is based on glibc 2.27 released commit.
(commit 406e7a023158b08a0908f381459f273a984c6fd328363cb)
I will follow your comment to modify and test the port based on the latest glibc
version again.

No. For a glibc port to go upstream, all the build dependencies must be
upstream (generally meaning GCC, binutils, Linux kernel - and, likewise,
if one of those ports is removed upstream, that means the glibc port will
be removed as well, as recently happened to the tile port because that
Linux kernel port was removed). They only need to be upstream in the
respective development mainlines, not on release branches.
