Compiling nolibc-test.c for rv32 got such error:
tools/testing/selftests/nolibc/nolibc-test.c:599:57: error: ‘__NR_fstat’ undeclared (first use in this function)
599 | CASE_TEST(syscall_args); EXPECT_SYSER(1, syscall(__NR_fstat, 0, NULL), -1, EFAULT); break;
The generic include/uapi/asm-generic/unistd.h used by rv32 doesn't
support __NR_fstat, use the more generic __NR_statx instead:
Running test 'syscall'
69 syscall_noargs = 1 [OK]
70 syscall_args = -1 EFAULT [OK]
__NR_statx has been added from v4.10:
a528d35e8bfc ("statx: Add a system call to make enhanced file info available")
It has been supported by all of the platforms since at least from v4.20.
Fixes: 8e3ab529bef9 ("tools/nolibc/unistd: add syscall()")
