From 6ed0492f8e47e2d0859105ab0f758b806853125b Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 22 Oct 1996 23:29:26 +0000 Subject: update from main archvie 961022 Tue Oct 22 21:38:21 1996 Ulrich Drepper * version.h: Bump version number to 1.97. * features.h: Undo change of Sun Oct 20 22:19:58 1996. Include libc-version.h. * features.h.in: Removed. * Makefile: Change rules to generate libc-version.h instead of features.h. * malloc/free.c: Add cast to prevent warning. * malloc/malloc-walk.c: Likewise. * malloc/ralloc.c: Likewise. * malloc/realloc.c: Likewise. * grp/fgetgrent_r.c: Accept empty numeric field if name start with + or -. * pwd/fgetpwent_r.c: Likewise. * nss/nss_files/files-grp.c: Don't accept entries with names starting with + or - in lookup functions. * nss/nss_files/files-pwd.c: Likewise. * Makerules: Call autolock.sh using $(SHELL). Mon Oct 21 22:52:16 1996 NIIBE Yutaka * elf/dl-minimal.c: Don't define `dgettext' replacement but `dcgettext'. When optimizing the macros in define `dgettext' as a macro and so this function will never be called. Mon Oct 21 15:41:59 1996 Ulrich Drepper * sysdeps/i386/sysdep.h: Define END to use .size when available. (PSEUDO_END): Use END. * sysdeps/unix/sysv/linux/i386/sysdep.h: Define PSEUDO_END to define SYSCALL_ERROR_HANDLER before using END. (SYSCALL_ERROR_HANDLER): Don't use .size directive. * sysdeps/unix/sysv/linux/clone.S: Don't use SYSCALL_ERROR_HANDLER and .size directive but PSEUDO_END. * sysdeps/unix/sysv/linux/mmap.S: Likewise. * sysdeps/unix/sysv/linux/socket.S: Likewise. * sysdeps/unix/sysv/linux/syscall.S: Likewise. * sysdeps/unix/sysv/linux/sysdep.S (__errno_location): Use END. * sysdeps/unix/i386/sysdep.S (__syscall_error): Likewise. * sysdeps/i386/__longjmp.S: Use END instead of PSEUDO_END. * sysdeps/i386/bsd-_setjmp.S: Likewise. * sysdeps/i386/bsd-setjmp.S: Likewise. * sysdeps/i386/memchr.S: Likewise. * sysdeps/i386/memcmp.S: Likewise. * sysdeps/i386/setjmp.S: Likewise. * sysdeps/i386/stpcpy.S: Likewise. * sysdeps/i386/stpncpy.S: Likewise. * sysdeps/i386/strchr.S: Likewise. * sysdeps/i386/strcspn.S: Likewise. * sysdeps/i386/strpbrk.S: Likewise. * sysdeps/i386/strrchr.S: Likewise. * sysdeps/i386/strspn.S: Likewise. * sysdeps/i386/strtok.S: Likewise. * sysdeps/i386/i486/strcat.S: Likewise. * sysdeps/i386/i486/strlen.S: Likewise. * sysdeps/i386/i586/memset.S: Likewise. * sysdeps/i386/i586/strchr.S: Likewise. * sysdeps/i386/i586/strlen.S: Likewise. * sysdeps/i386/strlen.c: De-ANSI-fy. * sysdeps/generic/_strerror.c: Undo change of Mon Oct 21 01:32:36 1996. Define dgettext if not defined to use dcgettext. * sysdeps/mach/_strerror.c: Likewise. * sysdeps/unix/sysv/i386/time.S: Add PSEUDO_END to get __syscall_error defined.. Sat Oct 19 12:27:50 1996 Andreas Schwab * sysdeps/unix/sysv/linux/m68k/mmap.S: Fix braino: CALL_MCOUNT is already included in the ENTRY macro.

Use JUMPTARGET. * sysdeps/generic/sysdep.h (END): Provide default empty definition. * sysdeps/unix/sysv/linux/m68k/sysdep.h (END): Redefine to use size directive. (PSEUDO): Don't include SYSCALL_ERROR_HANDLER. (PSEUDO_END): Include it here instead. (SYSCALL_ERROR_HANDLER): Remove type directive. * sysdeps/m68k/bsd-_setjmp.S: Use END, not PSEUDO_END. * sysdeps/m68k/bsd-setjmp.S: Likewise. * sysdeps/unix/sysv/linux/m68k/sigreturn.S: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.S: Likewise.
