1998-08-20 16:01 Ulrich Drepper <drepper@cygnus.com> * elf/ldd.sh.in: Redirect warnings and error messages to stderr. * elf/ldd.bash.in: Likewise. * elf/sln.c: Avoid warning for no main prototype. * sysdeps/unix/sysv/linux/alpha/bits/fcntl.h: Remove O_READ and O_WRITE. * sysdeps/unix/sysv/linux/mips/bits/fcntl.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/fcntl.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/fcntl.h: Add F_SETSIG and F_GETSIG. * sysdeps/unix/sysv/linux/bits/fcntl.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/fcntl.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/fcntl.h: Likewise. 1998-08-20 Philip Blundell <pb@nexus.co.uk> * sysdeps/arm/fpu/ieee754.h: Move to... * sysdeps/arm/ieee754.h: ... here. * sysdeps/arm/__longjmp.S: Put return value in correct register. Don't set the condition flags unnecessarily. * sysdeps/arm/fpu/__longjmp.S: Likewise. Restore floating point registers correctly. * sysdeps/arm/dl-machine.h: Fix problems with profiling code (patch from Scott Bambrough). * sysdeps/arm/sysdep.h (CALL_MCOUNT): Add missing semicolons. * csu/initfini.c (_init): Don't check whether __gmon_start__ is NULL, just call it unconditionally. (__gmon_start__): Provide stub version as a weak symbol. 1998-07-30 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/init-first.h: New file (from patch by Scott Bambrough) * sysdeps/unix/sysv/linux/arm/errlist.c: New file; ARM tools don't like `@' in .type directives. * sysdeps/arm/bsd-setjmp.S: Use PLT for procedure call. * sysdeps/arm/bsd-_setjmp.S: Likewise. * sysdeps/arm/dl-machine.h: Set __libc_stack_end. 1998-08-20 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/mips/bits/fcntl.h (F_SETOWN): Correct value. (F_GETOWN): Likewise. * sysdeps/unix/sysv/linux/bits/siginfo.h (SI_SIGIO): Add it (from Linux 2.1.117). 1998-08-20 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/glob.c [_LIBC]: Define __stat only if not already defined. 1998-08-14 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nss_compat/compat-grp.c: Set errno to ENOENT if we have no more entries. * nis/nss_compat/compat-initgroups.c: Likewise. * nis/nss_compat/compat-pwd.c: Likewise. * nis/nss_compat/compat-spwd.c: Likewise. * nis/nss_nis/nis-alias.c: Likewise. * nis/nss_nis/nis-ethers.c: Likewise. * nis/nss_nis/nis-grp.c: Likewise. * nis/nss_nis/nis-hosts.c: Likewise. * nis/nss_nis/nis-initgroups.c: Likewise. * nis/nss_nis/nis-network.c: Likewise. * nis/nss_nis/nis-proto.c: Likewise. * nis/nss_nis/nis-pwd.c: Likewise. * nis/nss_nis/nis-rpc.c: Likewise. * nis/nss_nis/nis-service.c: Likewise. * nis/nss_nis/nis-spwd.c: Likewise. * nis/rpcsvc/yp.h: Generate new without 1024 byte limits. * nis/ypclnt.c: Try binding dir only first time, could be to old. * nis/yp_xdr.c: Remove 1024 byte limit. * nis/ypupdate_xdr.c: Likewise. * nis/nss_nis/nis-publickey.c: Make sure, nobody could send wrong data.
