Thu Jun 13 17:25:11 1996 David Mosberger-Tang <davidm@azstarnet.com>cvs/libc-960619
* sysdeps/generic/memcmp.c: Add prototype decls for internal fns. * locale/programs/locale.c: Include string.h. * sunrpc/xdr_stdio.c (xdrstdio_getlong), sunrpc/xdr_rec.c (xdrrec_getlong), sunrpc/xdr_mem.c (xdrmem_getlong): Make sure appropriate sign-extension is performed on machines with sizeof(long) > 4. * sunrpc/xdr.c (xdr_int, xdr_u_int): If sizeof(long)==8 and sizeof(int)<sizeof(long), we need to go through a temporary variable. * locale/programs/ld-numeric.c: Include <alloca.h> * libio/stdio.h (__libc_fatal): Add prototype. * libio/cleanup.c: Use __P() to declare prototype when __STDC__ is in efect. * libio/iopopen.c (read_or_write, parent_end, child_end): Declare volatile to avoid "might get clobbered by longjmp" warning. * features.h (__KERNEL_STRICT_NAMES): Define __KERNEL_STRICT_NAMES unless _LOOSE_KERNEL_NAMES is in effect (which, with high probability is a sure loser). * sysdeps/unix/sysv/linux/gnu/types.h (__KERNEL_STRICT_NAMES): Remove. * sysdeps/unix/bsd/osf/alpha/start.S (errno): Removed. * sysdeps/unix/sysv/linux/alpha/start.S: Ditto. * misc/paths.h (_PATH_MAN): Change from /usr/share/man to /usr/man to be Linux FSSTND compliant. Mon Jun 10 17:50:31 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/pipe.S: Use PSEUDO. * sysdeps/unix/sysv/linux/alpha/sysdep.S, sysdeps/unix/sysv/linux/alpha/brk.S, sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S, sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S, sysdeps/unix/sysv/linux/alpha/llseek.S, sysdeps/unix/sysv/linux/alpha/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/syscall.S: Rename syscall_error to __syscall_error to avoid intruding application name space. * sysdeps/unix/sysv/linux/alpha/sysdep.h: Rename __NR_get?id to SYS_get?id so that syscall stubs in sysdeps/unix define these syscalls in terms of getxpid/getxuid/getxgid. * sysdeps/unix/_exit.S, sysdeps/unix/getegid.S, sysdeps/unix/geteuid.S, sysdeps/unix/getppid.S, sysdeps/unix/execve.S, sysdeps/unix/fork.S, sysdeps/unix/syscall.S: Terminate syscall with PSEUDO_END. * sysdeps/unix/make-syscalls.sh, sysdeps/unix/sysdep.h (PSEUDO_END): Rename END() to PSEUDO_END(). * sysdeps/unix/alpha/sysdep.h: Move error-handling code in PSEUDO to PSEUDO_END to improve branch-prediction. Include .frame directive to make syscalls debugabble. (PSEUDO_END): New macro. * sysdeps/unix/alpha/sysdep.h, sysdeps/alpha/bb_init_func.S, sysdeps/unix/sysv/linux/alpha/brk.S: Use ldiq instead of ldi since latter is illegal under DEC Unix. * sysdeps/unix/alpha/sysdep.S: Renamed from sysdeps/unix/sysv/linux/alpha/sysdep.S. This file works for OSF/1 as well. * sysdeps/unix/bsd/osf/alpha/sysdep.S: Remove (note that the EWOULDBLOCK -> EAGAIN mapping was unnecessary since EWOULDBLOCK==EAGAIN under DEC Unix and Linux/Alpha). * sysdeps/alpha/divrem.h: Use retaddr instead of ra as the return address register in the .frame directive. * sysdeps/alpha/copysign.c: Remove. * sunrpc/rpc/types.h: Include <sys/param.h> and <netinet/in.h> to avoid RPC definitions of INADDR_LOOPBACK and/or MAXHOSTNAMELEN. * errno.h: Move __END_DECLS to correct place to make file compilable under c++. * dirent/dirent.h: Document _DIRENT_HAVE_D_OFF macro. Define d_ino only if <direntry.h> hasn't defined d_fileno. * configure.in (HAVE_ASM_WEAKEXT_DIRECTIVE): Reverse order of arguments to weakext to make .weakext detection work on ECOFF systems. * FAQ: Add Linux/Alpha to list of supported platforms. Mention that _validuser() has been replaced by __ivaliduser(). Thu Jun 6 21:39:38 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/bsd/sun/sunos4/tcsetattr.c (tcsetattr): Declare cmd as unsigned long, not as int (to avoid incorrect int->long promotion).
