Update.
2000-09-28 Franz Sirl <Franz.Sirl-kernel@lauterbach.com> * sysdeps/unix/sysv/linux/kernel-features.h: Add __ASSUME_IPC64, only define it for powerpc for kernel >= 2.4.0. * sysdeps/unix/sysv/linux/msgctl.c: Test for __ASSUME_IPC64, not __ASSUME_32BITUIDS. * sysdeps/unix/sysv/linux/semctl.c: Likewise. * sysdeps/unix/sysv/linux/shmctl.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/ipc.h: Sync with kernel. * sysdeps/unix/sysv/linux/powerpc/bits/msq.h: New file. * sysdeps/unix/sysv/linux/powerpc/bits/sem.h: New file. * sysdeps/unix/sysv/linux/powerpc/bits/shm.h: New file. 2000-09-28 Martin Schwidefsksy <schwidefsky@de.ibm.com> * sysdeps/s390/atomicity.h: Fix compare_and_swap. * sysdeps/unix/sysv/linux/s390/bits/fcntl.h (F_GETLK64,F_SETLK64,F_SETLKW64): Use values from 2.4.0-test8. 2000-09-28 Denis Joseph Barrow <djbarrow@de.ibm.com> * sysdeps/unix/sysv/linux/s390/sys/procfs.h: Use definitions from ucontext.h. * sysdeps/unix/sysv/linux/s390/sys/ucontext.h: Fix ucontext structure. 2000-09-27 Andreas Schwab <schwab@suse.de> * math/Makefile (distribute): Explicitly add the long double test sources, to get them included even if long double is not supported. 2000-09-27 Jes Sorensen <jes@linuxcare.com> * elf/soinit.c (struct object): Move definition to gccframe.h and include it. Problem identified by HJ Lu. * sysdeps/ia64/gccframe.h: New file. ia64 specific version of struct object to be searched for frame unwind info. * sysdeps/generic/gccframe.h: New file. Generic version of struct object to be searched for frame unwind info. 2000-09-28 Ulrich Drepper <drepper@redhat.com> * manual/errno.texi: Correct error text for ENXIO. Reported by Jörg Schilling <schilling@fokus.gmd.de>. 2000-09-27 Jes Sorensen <jes@linuxcare.com> * sysdeps/ia64/fpu/fsetexcptflg.c (fesetexceptflag): Set the exception status bits rather than the exception disable bits. Don't include math.h. * sysdeps/ia64/fpu/fgetexcptflg.c (fegetexceptflag): Report the status of exceptions currently raised rather than which exceptions are enabled. * sysdeps/ia64/fpu/fclrexcpt.c (feclearexcept): Typecase to fenv_t rather than unsigned long int. * sysdeps/ia64/fpu/fedisblxcpt.c (fedisableexcept): Only disable the exceptions actually requested by the caller and not just disable all exceptions. * sysdeps/ia64/fpu/feenablxcpt.c (feenableexcept): Exceptions on the ia64 are enabled by clearing the respective bits in the fpsr, not setting them. * sysdeps/ia64/bits/fenv.h: typedef fexcept_t and fenv_t to unsigned long int rather than unsigned long to be consistent with the coding conventions. 2000-09-20 H.J. Lu <hjl@gnu.org> * sysdeps/ia64/fpu/fesetenv.c (fesetenv): Use fenv_t instead of unsigned long int. * sysdeps/ia64/fpu/fesetround.c (fesetround): Likewise. 2000-09-28 Ulrich Drepper <drepper@redhat.com> * string/bits/string2.h: Unify #if usage. 2000-09-27 Jakub Jelinek <jakub@redhat.com> * math/test-fenv.c (feexcp_mask_test): If enabling all exceptions and disabling underflow or overflow, disable inexact as well. * sysdeps/gnu/netinet/tcp.h: Add tcp_info defines and types.
