This is the 6th version of nds32 ports. The major modification in this
patchset is to change the data length of off_t, rlim_t, fsblkcnt_t,
fsfilcnt_t and ino_t from 32 bits to 64 bits, because in all nds32
supported kernel, these data types used by syscall handler are 64 bits
version. Hence, It seems a bit pointless to uses 32 bits version of
these types in user space. Thanks to Arnd Bergmann for this suggestion.
All CPU-relative information can be found from
<http://www.andestech.com/en/products-solutions/product-documentation/>.
The ISA and ABI used in nds32 ports are documented in the "AndeStar ISA Manual"
and "Andes Programming Guide for ISA V3", respectively.
The patchset has been tested by glibc testsuite on FPGA board based on
kernel 5.0 and glibc commit "fefa21790". In addition to the known
architecture-independent issues on the per-release wiki pages, there are three
unexpected FAIL cases, libio/tst-wfile-sync, io/tst-lockf and timezone/tst-tzse.
The reasons for their failure are as follows.
1. libio/tst-wfile-sync
In the testcase, an unexpected Error code -ESPIPE retunred by the function
xlseek() causes this testcase to fail. This is an architecture independent
issue and I have reported it to Bugzilla (Bug 24668).
2. io/tst-lockf
When the macro __OFF_T_MATCHES_OFF64_T is defined, the __lockf64 function
shall be used instead of lockf. However, in lockf.c, the typesizes.h which
defines the macro __OFF_T_MATCHES_OFF64_T is included after the
condition "ifndef __OFF_T_MATCHES_OFF64_T". It causes that lockf is always
linked. I have sent a patch to fix this bug.
(https://sourceware.org/ml/libc-alpha/2019-06/msg00856.html)
3. timezone/tst-tzset
When the data length of off_t is extend from 32 bits to 64 bits, the file
offset does not overflow after calling function
lseek(fd,0xffffffff-6,SEEK_CUR). However, the maximum offset of file system
does not changed in kernel. Hence, if the file system does not support file
offsets greater than 0xffffffff, the function write(fd,,1) will return the
EFBIG error code and the testcase will fail.

This patchset cannot be compiled due to the lack of the Linux 4 hash code.
I have sent a patch to add it (https://sourceware.org/ml/libc-alpha/2019-06/msg00962.html)
The following logs for build and make check by build-many-glibcs.py has
included the above patch.
