This is the fourth version of the nds32 port. I am sorry that one year has
passed since the previous submission. The most obvious modification in this
version patchset is that FPU extension is supported now.In addition,
the mainline of gcc and binutils has contained the nds32 ports.Hence, the
nds32 toolchain without FPU extension support can be derived through
build-many-glibcs.py. The toolchain with FPU extension needs an extra kernel
patchset to successfully compile. This patchset has been pulled and may be
released in 5.2 rc-4. The implementations for nds32 FPU extension are like
other architecture except for the following two parts.
Part 1. The calling convention for variable argument function.
The ABI of nds32 FPU is different to the original ABI, especially
in the transmission of variable arguments.In nds32 original ABI, if
the summation of the number of variable arguments and the constant
arguments are lesser than 6, the caller function still uses general
purpose register to pass the variable argument.However, in nds32 FPU
extension ABI, the caller function directly places the variable
arguments to stack no matter what the number of argument. This causes
these functions with variable arguments cannot use internal_syscallX
macro to issue syscall. Hence the generic builds from syscalls.list
cannot be used for nds32 FPU extension ABI.
Part 2. Overcome the limitation of nds32 FPU on denormalize output.
For most floating point instructions, the denormalized output is
treated as an underflow case.Hence, if the underflow trap is not
enabled, the output is rounded to a normalized number according to
the rounding mode. The accuracy loss from the approximation is
possibly not acceptable for some applications. Hence we added an nds32
specific feature that the kernel can intervene in this kind of
floating point operation and recalculate it by kernel's soft-fp
module.In order for the kernel to capture each denormalized output,
the underflow and inexact bit in $fpcsr, floating pointer control
status register, should be set when this feature is enabled in the
kernel. In addition, a new kernel parameter, UDF_IEX_trap, replaces
$fpcsr to control the state of the user's inexact and underflow trap.
Hence each operation as regard the floating point environment needs to
issue a syscall with the number NR_fp_udfiex_crtl to access the
parameter UDF_IEX_trap to get the state of inexact and underflow trap.
In this mechanism, kernel uses the initial value of $fpcsr to notify
glibc whether this feature is enable or not. To avoid overriding the
initial value of $fpcsr, nds32 specific function __setfpucw is defined.
From the recent discussions in mailing list, I know that the functions such as
clock_settime for Y2038-proof syscall are under development, and I guess that
these functions may not ready before glibc-2.30 code freeze. If nds32 port is
approved by maintainers to the upstream in glibc-2.30 release, does it mean
nds32 ports need to support Y2038-incompatiable functions ? Please correct me
if I have wrong understanding.
The patchest has been cross-tested on the FPGA board based on Linux 5.2 rc-2
and glibc commit 004e52f ebf30012ab (May 21).

A. Summarize for test results
A1. nds32 port with FP extension toolchain
53 FAIL (15 XFAIL cases are not included)
4983 PASS
34 UNSUPPORTED
A2. nds32 port
32 FAIL (15 XFAIL cases are not included)
5003 PASS
34 UNSUPPORTED
The FAIL cases of nds32 FP extension toolchain are same to the nds32
toolchain except for 20 FAIL cases in math and stdlib/tst-tininess.
nds32 toolchain pass these 21 testcases.
B. The analysis of FAIL cases:
1. The following 20 cases have same error behevior, namespace violation:
"SIOCGSTAMP_OLD", "SIOCGSTAMPNSD", "fds_bits" and "val". The cause of
the first two cases, "SIOCGSTAMP_OLD" and "SIOCGSTAMPNSD", is the same
that Linux kernel recently added the definition of these two macros in
asm-generic/sockios.h. For the last two cases, kernel header
uapi/asm-generic/socket.h includes linux/posix_types.h instead of
asm/bitsperlong.h. This change introduces the two variables "fds_bits"
and "val" declared in the linux/posix_types.h and
asm-generic/posix_types.h.

2. locale/tst-locale-locpath
I found that the failure is caused by missing the environment parameter
when this testcase is executed on FPGA through cross-test-ssh.sh. I try
to modify the Makefile rule of tst-locale-locpath.out to "$(SHELL) $<
'$(common-objpfx)' '$(test-wrapper-env)' '$(run_program_env)' > $ @;"
.However, the content of $ (run_program_env) is empty so that the
environment parameter is still empty.
The testcase passed if I set the environment parameters by manually.
3. libio/tst-wfile-sync.test-result
The testcases will try to operate the standard input file by lseek
function. However, the standard input is pipe instead of file if this
testcase run on FPGA through cross-test-ssh.sh. This causes testcase gets
an unexpected error ESPIPE from the return of the lseek function.
The testcase passed if it was directly executed on FPGA board.
4. sysvipc/test-sysvsem.test-result
This testcase fails due to unexpected error number, EINVAL, from
function semtimedop. The bug is due to wrong syscall handler of
NR_semtimedop for native 32bit architecture. In Linux 5.2 rc2, the syscall
handler selection of NR_semtimedop is through
__SC_COMP(__NR_semtimedop, sys_semtimedop, sys_semtimedop_time32). It
makes the native 32-bit architecture always select the function
sys_semtimedop as the syscall handler, which uses a 64-bit timespec to
parse the input parameter timeout. I had sent a mail to check the
correctness of above deductions with Arnd Bergmann before submitting this
patchset.
6. The soft-fp module in Linux kernel is too old to the following 21 cases
cannot pass.
FAIL: math/test-double-finite-lround
FAIL: math/test-double-lround
FAIL: math/test-float-double-add
FAIL: math/test-float-double-sub
FAIL: math/test-float-ldouble-add
FAIL: math/test-float-ldouble-sub
FAIL: math/test-float32-float32x-add
FAIL: math/test-float32-float32x-sub
FAIL: math/test-float32-float64-add
FAIL: math/test-float32-float64-sub
FAIL: math/test-float32x-finite-lround
FAIL: math/test-float32x-lround
FAIL: math/test-float64-finite-lround
FAIL: math/test-float64-lround
FAIL: math/test-ldouble-finite-lround
FAIL: math/test-ldouble-lround
FAIL: math/test-float32-fma
FAIL: math/test-float-fma
FAIL: math/test-float32-finite-fma
FAIL: math/test-float-finite-fma
FAIL: stdlib/tst-tininess
The cause of failure can be divided to two parts.
Part 1. If the value can be rounded to most negative integer, the result
of FP_TO_INT_D or FP_TO_INT_ROUND_D is incorrect. The example
case is lround (-0x80000000.4p0). In this case, FP_TO_INT_D
returns most negative integer 0x80000000 and raises the Invalid
exception flag.
Part 2. To Overcome the limitation of nds32 FPU on denormalize output,
any underflow and inexact case will issue a FPU trap that
notifies the kernel to recalculate the floating point operation
through kernel's soft-fp module. However, the soft-fp module in
Linux kernel does not support TININESS_AFTER_ROUNDING but nds32
FPU is TININESS_AFTER_ROUNDING. This mismatch causes some
testcases to fail because the underflow exception flag is raised,
such as stdlib/tst-tininess, add_double (-0x4p-1024, 0x4p-128)
and fma (-0x7.ffffep-128, 0x8.00001p-4, -0x8p-152).
I tried to port the latest soft-fp module from glibc to kernel, and the
above 21 failed testcases turned into PASS based on the latest soft-fp
module. By the way, I found that Joseph tried to update the soft-fp
module in Linux kernel in 2015, but the last status of the patchset seems
to remain pending due to the lack of ACK from sparc maintainer. Does
Joseph have any plans to resend the patchset?
7. misc/tst-syscall-list
This case turns to PASS if I add NR_fp_udfiex_crtl to
linux/syscall-names.list
The remaining FAIL cases are same with v3 patchest
8. The following 6 testcase fail because the testing environment lacks
native python:
./nptl/test-condattr-printers
./nptl/test-cond-printers
./nptl/test-mutexattr-printers
./nptl/test-mutex-printers
./nptl/test-rwlockattr-printers
./nptl/test-rwlock-printers
9. stdio-common/bug22
The required memory size for this testcase is more than 2 GB but
the DRAM size on our FPGA is just 2GB. Therefore, the errno is set as
ENOMEM instead of EOVERFLOW.
10. bug20790.test-result
It fails because the testing environment lacks native cpp

The nds32 toochain cannot be generated successfully by this patch because
the nds32 port of Binutils and GCC on upstream is too old. This patch is
used to help reviewer to review the glibc port for Andes nds32 ISA.

Since the base version is GLIBC_2.30, it doesn't make sense to reference
an earlier version.

I think the actual system call name is fp_udfiex_crtl, and this can go
in immediately as a separate patch (it's not necessary to wait for the
upstream kernel release).

Yes, the actual system call name is fp_udfiex_crtl. I will use a
separate patch to complete it in the next version patchset.

Please see <https://sourceware.org/glibc/wiki/NewPorts> and make sure the
port submission follows what is described there. In particular: (a) give
pointers to the relevant instruction set and ABI manuals
(<https://gcc.gnu.org/readings.html> points to a page with a great many
manuals, pointers directly to exactly the ones that are relevant would be
helpful); (b) fix coding style issues, such as brace positioning,
indentation and missing spaces before '('.

fds_bits and val are a generic Linux kernel issue - a patch was sent to
linux-api in March and acked by David Miller but still didn't get into the
Linux kernel in 5.1 (and, indeed, still hasn't got into the kernel). I'm
not sure what the holdup is there, but for now we should assume that Linux
kernel header versions later than 5.0 are not suitable for use in glibc
(and so probably avoid adding any new ports depending on newer kernel
header versions, because of the possibility of being unable to test them
effectively for an indefinite period while build-many-glibcs.py is stuck
on 5.0).
The others also sound like a generic issue. Please *start a separate
thread on them, not part of the port submission*. Is this like the case
where sysdeps/unix/sysv/linux/bits/socket.h has
/* Ugly workaround for unclean kernel headers. */
for some existing macros? If so, you should send a patch for that,
extending the workaround to the new macros (again, not part of the port
submission, not marked as part of the port submission, because it's an
independent issue).

Again, start an independent thread on this issue. I'm not sure if
$(run_program_env) should be passed at all (given how this test is
deliberately overriding the default environment), but in any case, the
call in the Makefile should be consistent with the test script - and this
needs to be discussed outside the context of a port submission.

Likewise, start a separate thread, not marked as part of a port
submission, for any such architecture-independent issue; resolve such
issues first and ensure the port submission only needs to include
genuinely architecture-specific patches.

No. It was accepted by the powerpc maintainers into a branch with a
statement "I'll ask Stephen to put it in linux-next once 4.3-rc1 is out,
and I'll ask Linus to pull it for 4.4". I don't know what the holdup is
that stopped it going further. There was an issue with sparc compilers
that didn't default to -mlong-double-128, but a patch for that was added
in Nov 2015. There was a build robot reporting new warnings on sh but I
didn't think they indicated any actual problems that were new with the
patch (which was acked for sh).
Since that patch series deals with the hard part of an update (i.e.
updating the kernel code across several architectures for extensive API
changes in glibc soft-fp made as part of the optimization project
described in the GCC Summit 2006 proceedings, and subsequently), I think
it makes sense to integrate that patch series more or less as I posted it
(plus, I suppose, a corresponding nds32 patch), and then possibly follow
up with another update of the code to the latest glibc version (much
easier because of the lack of API changes needing all-architectures
fixes).
Note: I have a long list of issues with the powerpc math emulation in the
Linux kernel (i.e., the architecture-specific code) that could reasonably
be fixed after that series is in, and shorter lists for alpha and sh (all
of those are lists as of 2015, I don't know if some of the issues might
have been fixed in the kernel since then).

These are on the list of known architecture-independent issues on the
per-release wiki pages, thus can be ignored for the purposes of the
expectation of no more than 20 architecture-specific test failures.

Example of a coding style issue, should have the function name in a

This only applies in definitions, not in function declarations that are
not definitions. Please fix everywhere in the patch series.

Example of a coding style issue, '{' should go on its own line, indented
two columns from the line above (and then the contents of the block should

__ctx is only expected to be used for old ports where there might be
existing code relying on the old names and we want as much API
compatibility as possible. For new ports, just use the __* names in this
header unconditionally rather than having such a macro at all.

For a new port to go into glibc, the upstream mainline versions of
binutils / GCC / Linux kernel need to have all the features required to
build the port and run tests with good results (even if release branches
are too old to work well - though if it's just a matter of bug fixes,
backporting those to release branches may be a good idea). Ports
depending on non-upstream changes to those components can't be accepted
(we had trouble in the past with MicroBlaze and NaCl depending on things
that weren't upstream, fixed by getting some MicroBlaze GCC patches
upstream and removing the NaCl port; we don't want to go there again).

You can submit this change separately any time, it is not tied to the
port.

OK, I got it. I will remove __ctx macro and replace __ctx with prifix __.
Also, I will fix the above codeing style issues in the next submission.

Sorry, I did not find the commit log is out-of-day. Now, build-many-glibcs.py
can use upstream Binutils-2.32, GCC-9.0.1 and this patchset to generate nds32
toolchain and pass the test. I will correct this commit log and append the
test log in the next submission.
Thanks,

Ok, I will develop nds32 ports based on kernel 5.0 before relevant issues
are fixed in kernel.

Yes, the issue of the macros "SIOCGSTAMPNS_OLD" and "SIOCGSTAMP_OLD" is similar
to the case in sysdeps/unix/sysv/linux/bits/socket.h. I will send a separate
patch to add these two macros to the workaround list.
