From 5580f1544d434997f1ddfbb4785a7a447f75e605 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 25 Oct 2002 19:41:31 +0000 Subject: * sysdeps/unix/sysv/linux/init-first.c (init): Remove [! SHARED] conditional from __libc_multiple_libcs access. Remove kludge for weak symbol access with old compilers we no longer support. * sysdeps/unix/sysv/aix/init-first.c (init): Likewise. * sysdeps/generic/libc-start.c (__libc_start_main): Likewise. 2002-10-24 Roland McGrath * sysdeps/generic/ldsodefs.h (struct rtld_global): New member `_dl_tls_static_used'. (TLS_STATIC_MIN): New macro. * sysdeps/generic/libc-tls.c (_dl_tls_static_used): New variable. (__libc_setup_tls): Initialize it. * sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Likewise. * elf/dl-reloc.c [USE_TLS] (allocate_static_tls): New function. (CHECK_STATIC_TLS): Use it. * elf/dl-close.c (_dl_close): Adjust _dl_tls_static_used when the closed objects occupied a trailing contiguous chunk of static TLS area. 2002-10-25 Roland McGrath --- ChangeLog | 21 +++++++++++++++++++++ sysdeps/generic/libc-start.c | 7 +------ sysdeps/unix/sysv/aix/init-first.c | 6 +----- sysdeps/unix/sysv/linux/init-first.c | 9 +-------- 4 files changed, 24 insertions(+), 19 deletions(-) diff --git a/ChangeLog b/ChangeLog index 1394bab473..b75b5ef964 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,24 @@ +2002-10-25 Roland McGrath + + * sysdeps/unix/sysv/linux/init-first.c (init): Remove [!
