Update.
1998-08-24 16:34 Ulrich Drepper <drepper@cygnus.com> * debug/catchsegv.sh: Handle text preceding backtrace better. * sysdeps/generic/segfault.c: Allow register dump. Allow handler to be installed for other signals than SIGSEGV. * sysdeps/generic/register-dump.h: New file. * sysdeps/i386/register-dump.h: New file. * sysdeps/powerpc/register-dump.h: New file. * sysdeps/unix/sysv/linux/i386/profil-counter.h: Use macros from sigcontextinfo.h. * sysdeps/unix/sysv/linux/powerpc/profil-counter.h: Use i386 version. 1998-08-24 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/sigcontextinfo.h: New file. 1998-08-09 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/chown.c: New file. * sysdeps/unix/sysv/linux/powerpc/lchown.S: New file. * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add chown, remove getresuid, getresgid. 1998-08-16 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/clone.S: Fix bugs. Set up stack pointer in userland. 1998-08-21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/sys/mount.h (MNT_FORCE): Define as enum and fix value. 1998-08-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/ldd.bash.in: Add missing quotes around $file. Make loop over arguments Bourne shell compatible. Don't exit unsuccessfully if nonelf returns successfully. Avoid duplicating most of the script. * sysdeps/unix/sysv/linux/ldd-rewrite.sed: Add missing quotes around $file. 1998-08-24 10:37 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * libio/Versions (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Added to GLIBC_2.1. * libio/fileops.c (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Change the prefix to "_IO_new_".
