From 49b986270035c7f86c3dc85383fd1da2e413fef9 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 18 Jul 1996 08:43:26 +0000 Subject: Thu Jul 18 04:33:21 1996 Roland McGrath * sysdeps/mach/hurd/errnos.awk: Move EWOULDBLOCK check before errno==0 check. mib's clueless hacking broke it. Thu Jul 18 04:27:21 1996 Roland McGrath * Makerules ($(libdir)/libc.so): Add missing / after $(cryptobjdir). Wed Jul 17 10:54:20 1996 David Mosberger-Tang * sysdeps/unix/sysv/linux/alpha/start.S: Move to ... * sysdeps/alpha/elf/start.S: here. * misc/sys/ustat.h: New file. * misc/ustat.h: Ditto. * sysdeps/generic/ustatbits.h: Ditto. * libc-orig/sysdeps/stub/ustat.c: Ditto. * sysdeps/unix/sysv/linux/ustatbits.h: Ditto. * misc/Makefile (headers): Mention ustat.h, sys/ustat.h, and ustatbits.h. (routines): Mention ustat. * sysdeps/unix/sysv/linux/syscalls.list: Mention klogctl in alphabetically correct place. Mention ustat. * sysdeps/unix/alpha/sysdep.S: Make errno a bss symbol, not a common symbol (makes errno accessible from gdb). * login/pututline_r.c (pututline_r): Test ut_id in repositioning test, not ut_type. * login/logwtmp.c (logwtmp): Reimplemented. Must ensure that a record always gets appended at end of file (wtmp is a log file, after all). Set ut_type to DEAD_PROCESS if name is empty. * login/getutid_r.c (getutid_r): Handle search for UT_TYPE in separate loop from search for UT_ID. Fix code so it is in sync with Unix man page. * login/getutline_r.c (getutline_r): Stop searching only if ut_line matches and type is either USER_PROCESS or LOGIN_PROCESS. Tue Jul 16 15:06:18 1996 David Mosberger-Tang * sysdeps/unix/sysv/linux/netinet/in.h: Base on to avoid duplicate declarations. Sun Jul 14 19:08:55 1996 David Mosberger-Tang * manual/maint.texi (Supported Configurations): Add alpha-gnu-linux and alpha-gnu-linuxecoff targets. Fri Jul 12 16:58:44 1996 David Mosberger-Tang * sysdeps/unix/sysv/linux/netinet/in.h: Declare bindresvport(). Sat Jun 22 23:30:07 1996 David Mosberger-Tang * resolv/res_send.c (res_send): Declare FROMLEN as size_t instead of int. * resolv/res_comp.c (res_hnok): Use empty statement in place of NULL (which generates a "useless expression" warning in gcc). --- sysdeps/alpha/elf/start.S | 104 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 104 insertions(+) create mode 100644 sysdeps/alpha/elf/start.S (limited to 'sysdeps/alpha/elf') diff --git a/sysdeps/alpha/elf/start.S b/sysdeps/alpha/elf/start.S new file mode 100644 index 0000000..c534d69 --- /dev/null +++ b/sysdeps/alpha/elf/start.S @@ -0,0 +1,104 @@ +/* Startup code for Alpha/ELF. +Copyright (C) 1993, 1995, 1996 Free Software Foundation, Inc. +Contributed by Richard Henderson + +The GNU C Library is free software; you can redistribute it and/or +modify it under the terms of the GNU Library General Public License as +published by the Free Software Foundation; either version 2 of the +License, or (at your option) any later version. + +The GNU C Library is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
