From dde2652bb6db2a9d524f46aafbac0112d1e7ae53 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 1 Dec 2002 22:14:57 +0000 Subject: [PATCH] * sysdeps/generic/libc-start.c (__libc_start_main): Do DL_SYSDEP_OSCHECK here. * sysdeps/unix/sysv/linux/init-first.c (init): Not here. * sysdeps/unix/sysv/linux/dl-osinfo.h: Include . * sysdeps/generic/libc-tls.c (__libc_setup_tls): Bail if argument TCBSIZE <= TLS_INIT_TCB_SIZE, not just if it's zero. * sysdeps/generic/dl-tls.c (_dl_allocate_tls_init): Check l_tls_offset instead of l_type to decide whether to use TLS_DTV_UNALLOCATED. * include/link.h: Comment typo fix. 2002-12-01 Roland McGrath * sysdeps/mach/hurd/bits/posix_opt.h (_POSIX_FSYNC): Set to 200112L. (_POSIX_SPAWN, _POSIX_MAPPED_FILES, _POSIX_MEMLOCK_RANGE, _POSIX_MEMORY_PROTECTION): Likewise.
