Update.
2002-10-09 Ulrich Drepper <drepper@redhat.com> * Versions.def (libc): Add GLIBC_2.3.1. (libpthread): Add GLIBC_2.3.1. * include/signal.h: Add libc_hidden_proto for __sigwait, __sigwaitinfo, and __sigtimedwait. * signal/Versions: Add __sigtimedwait, __sigwait, and __sigwaitinfo. * sysdeps/unix/sysv/linux/sigtimedwait.c (__sigtimedwait): Add libc_hidden_def. * sysdeps/unix/sysv/linux/sigwait.c (__sigwait): Likewise. * sysdeps/unix/sysv/linux/sigwaitinfo.c (__sigwaitinfo): Likewise. * include/sys/msg.h: Declare __libc_msgrcv and __libc_msgsnd. * sysdeps/unix/sysv/linux/msgrcv.c (__msgrcv): Rename to __libc_msgrcv and make old name an alias. * sysdeps/unix/sysv/linux/msgsnd.c (__msgsnd): Rename to __libc_msgsnd and make old name an alias. * sysvipc/Versions (libc) [GLIBC_PRIVATE]: Add __libc_msgrcv and __libc_msgsnd. * include/sys/uio.h: Declare __libc_readv and __libc_writev. * misc/Versions (libc) [GLIBC_PRIVATE]: Add __libc_readv and __libc_writev. * sysdeps/generic/readv.c (__readv): Rename to __libc_readv and make old name an alias. * sysdeps/posix/readv.c: Likewise * sysdeps/unix/sysv/aix/readv.c: Likewise. * sysdeps/unix/sysv/linux/readv.c: Likewise. * sysdeps/generic/writev.c (__writev): Rename to __libc_writev and make old name an alias. * sysdeps/posix/writev.c: Likewise * sysdeps/unix/sysv/aix/writev.c: Likewise. * sysdeps/unix/sysv/linux/writev.c: Likewise. * include/sys/wait.h: Declare __waitid. * posix/Versions (libc) [GLIBC_PRIVATE]: Add __waitid. * sysdeps/generic/waitid.c (waitid): Rename to __waitid and make old name an alias. * sysdeps/posix/waitid.c: Likewise. * sysdeps/unix/sysv/aix/waitid.c: Likewise. * sysdeps/unix/sysv/linux/syscalls.list: Add creat syscall. 2002-10-07 Jakub Jelinek <jakub@redhat.com> * include/alloca.h (__libc_use_alloca, __libc_alloca_cutoff): New prototypes. (__MAX_ALLOCA_CUTOFF): Define. Include allocalim.h. * resolv/nss_dns/dns-host.c (_nss_dns_gethostbyname2_r, _nss_dns_gethostbyaddr_r): Use alloca or malloc to allocate host_buffer depending on __libc_use_alloca. * resolv/nss_dns/dns-network.c (_nss_dns_getnetbyname_r, _nss_dns_getnetbyaddr_r): Use alloca or malloc to allocate net_buffer depending on __libc_use_alloca. * resolv/res_query.c (res_nquery): Use alloca or malloc to allocate buf depending on __libc_use_alloca. * resolv/gethnamaddr.c (gethostbyname2, gethostbyaddr): Likewise. * stdio-common/vfprintf.c (vfprintf): Use __libc_use_alloca instead of hardcoded constants. Pass proper size argument to alloca and compute end for wide char version. * stdio-common/printf_fp.c (__printf_fp): Use __libc_use_alloca instead of hardcoded constants. * string/strcoll.c (strcoll): Likewise. * string/strxfrm.c (strxfrm): Likewise. * sysdeps/posix/readv.c (__readv): Likewise. * sysdeps/posix/writev.c (__writev): Likewise. * sysdeps/generic/allocalim.h: New file.
