Myers" To: libc-ports@sourceware.org cc: Mike Frysinger , Andreas Schwab , Richard Henderson , Carlos O'Donell , Mark Salter Subject: Ports state for 2.16 regarding global changes Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Mailing-List: contact libc-ports-help@sourceware.org; run by ezmlm Precedence: bulk List-Id: List-Subscribe: List-Post: List-Help: , Sender: libc-ports-owner@sourceware.org X-SW-Source: 2012-06/txt/msg00048.txt.bz2 Here is my understanding of the current status of ports with regard to being updated for global changes in libc: * arm, ia64, linux-generic, mips, powerpc-nofpu, tile: up to date. However, ia64 libm-test-ulps may need regenerating / updating. * m68k: mostly up to date, but may need updates to its ccos / csin / ccosh / csinh implementations along the lines of my 2012-05-19 libc changes to avoid spurious overflows (bug 14123), and both m68k libm-test-ulps files may need regenerating / updating. * alpha: out of date in the following ways: (a) There are __GNUC_PREREQ conditionals in various non-installed files that should be removed because the versions in question are older than the minimum 4.3 version accepted for configuring GCC: sysdeps/alpha/fpu/cfloat-compat.h sysdeps/alpha/fpu/s_fabs.c sysdeps/alpha/fpu/s_fabsf.c sysdeps/unix/sysv/linux/alpha/sysconf.c. (b) bits/mathdef.h should be updated in line with my 2012-01-31 libc change so that float_t is always float rather than depending on __GNUC__. (c) sysdeps/alpha/soft-fp/sfp-machine.h is missing a definition of FP_TRAPPING_EXCEPTIONS. (d) sysdeps/unix/sysv/linux/alpha/bits/resource.h is missing RLIMIT_RTTIME. (e) sysdeps/unix/sysv/linux/alpha/bits/resource.h has a possible trailing comma in an enum outside __USE_GNU where the generic code has it inside __USE_GNU. (f) sysdeps/unix/sysv/linux/alpha/bits/resource.h is missing the prlimit and prlimit64 declarations. (g) sysdeps/unix/sysv/linux/alpha/bits/shm.h is missing SHM_EXEC. (h) sysdeps/unix/sysv/linux/alpha/bits/stat.h has a conditional "#if defined __USE_ATFILE || defined __USE_GNU" where other versions use "#ifdef __USE_ATFILE". * hppa: out of date in the following ways: (a) There is a stray file sysdeps/unix/sysv/linux/hppa/nptl/pt-initfini.c, which will be unused. (b) libm-test-ulps needs to be regenerated / updated. (c) There is no ____longjmp_chk implementation. (d) sysdeps/unix/sysv/linux/hppa/nptl/pthread_once.c has an alias __pthread_once_internal but this has been replaced by hidden_def for other architectures. (e) sysdeps/unix/sysv/linux/hppa/syscalls.list has a __connect_internal alias that has been removed for other architectures. (f) sysdeps/unix/sysv/linux/hppa/nptl/pthread.h uses __builtin_expect but the generic version now uses __glibc_unlikely instead. (g) There are no ABI test baselines for hppa. (h) hppa still has conditionals on or definitions of obsolete macros USE_TLS and USE___THREAD. (i) sysdeps/unix/sysv/linux/hppa/bits/errno.h is missing EHWPOISON (and any associated errlist-compat updates needed). A patch was submitted in but apparently not reviewed. (j) sysdeps/unix/sysv/linux/hppa/bits/fcntl.h is missing O_PATH. (k) sysdeps/unix/sysv/linux/hppa/bits/mman.h is missing MAP_STACK and MAP_HUGETLB. (l) sysdeps/unix/sysv/linux/hppa/bits/mman.h is missing MADV_HUGEPAGE, MADV_NOHUGEPAGE, MADV_DONTDUMP, MADV_DODUMP and MADV_HWPOISON. (m) sysdeps/unix/sysv/linux/hppa/bits/shm.h is missing SHM_EXEC. (n) sysdeps/unix/sysv/linux/hppa/bits/sigaction.h is missing the change to define SA_RESTART, SA_NODEFER and SA_RESETHAND if __USE_XOPEN2K8. (o) sysdeps/unix/sysv/linux/hppa/bits/socket.h still exists but socket_type.h should now be provided instead. (p) sysdeps/unix/sysv/linux/hppa/nptl/pthread.h defines __need_timespec before including but the generic version no longer does. (q) sysdeps/unix/sysv/linux/hppa/sys/epoll.h still exists but bits/epoll.h should now be provided instead. (r) sysdeps/unix/sysv/linux/hppa/sys/eventfd.h still exists but bits/eventfd.h should now be provided instead. (s) sysdeps/unix/sysv/linux/hppa/sys/inotify.h still exists but bits/inotify.h should now be provided instead. (t) sysdeps/unix/sysv/linux/hppa/sys/signalfd.h still exists but bits/signalfd.h should now be provided instead. (u) sysdeps/unix/sysv/linux/hppa/sys/timerfd.h still exists but bits/timerfd.h should now be provided instead. (v) sysdeps/unix/sysv/linux/hppa/syscalls.list is missing prlimit64 and fanotify_mark which means it is likely those functions are missing on hppa (and when added, will need appropriate Versions additions to avoid adding them to an old version). (w) An entry in libc's nptl/shlib-versions for hppa was removed on 2012-01-07 and a corresponding entry needs adding in ports. (x) An entry in libc's sysdeps/unix/sysv/linux/configure.in for hppa was removed on 2012-01-07 and a ports update may be needed. That entry may actually have been dead because of the arch_minimum_kernel setting in sysdeps/unix/sysv/linux/hppa/nptl/configure.in - but in that case, there's the question of whether the libc_cv_gcc_unwind_find_fde=yes that was in libc's file for hppa should go in the ports version (if that was a correct description of old libc binaries on hppa). (y) sysdeps/unix/sysv/linux/hppa/kernel-features.h still defines __ASSUME_32BITUIDS and __ASSUME_TRUNCATE64_SYSCALL (no longer used). * am33: generally massively out of date and I have not tried to identify specific changes needed. -- Joseph S.
