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 . 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.
