From aed283dd456e7566cbfef88abe7b235ca77cc23c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 13 Feb 2002 08:03:56 +0000 Subject: Update. 2002-02-12 Ulrich Drepper * sysdeps/generic/dl-tls.c (TLS_DTV_UNALLOCATED): Renamed from TLS_DTV_UNALLOCATE. (oom): New function. (_dl_next_tls_modid): Rewrite to handle dl_tls_dtv_slotinfo_list. (_dl_determine_tlsoffset): Likewise. (_dl_allocate_tls): Likewise. (__TLS_GET_ADDR): Define if not already defined. (_dl_tls_symaddr): New function. (allocate_and_init): New function. (__tls_get_addr): Actually implement handling of generation counter and deferred allocation. * sysdeps/generic/ldsodefs.h (_rtld_global): Remove _dl_initimage_list, add _dl_tls_dtv_slotinfo_list, _dl_tls_static_nelem, and _dl_tls_generation. Define TLS_SLOTINFO_SURPLUS and DTV_SURPLUS. Declare _dl_tls_symaddr. * sysdeps/i386/dl-tls.h: Disable __tls_get_addr handling unless SHARED. * include/link.h (struct link_map): Remove l_tls_nextimage and l_tls_previmage. * elf/dl-sym.c (_dl_sym): After successful lookup call _dl_tls_symaddr instead of DL_SYMBOL_ADDRESS for STT_TLS symbols. (_dl_vsym): Likewise. * elf/rtld.c (_dl_start_final): Adjust initdtv initialization for new layout. (dl_main): Allow PT_TLS be present for empty segment. Remove nextimage list handling. Instead add all modules using TLS to dl_tls_dtv_slotinfo_list. * elf/dl-open.c (dl_open_worker): After successfully loading all objects add those with TLS to the dl_tls_dtv_slotinfo_list list. * elf/dl-load.c (_dl_map_object_from_fd): If PT_TLS entry is for an empty segment don't do anything. Remove handling of initimage list. * elf/Versions [ld] (GLIBC_2.0): Add __libc_memalign. (GLIBC_PRIVATE): Add _dl_tls_symaddr. * elf/dl-minimal.c: Define __libc_memalign. * elf/dl-support.c: Remove _dl_initimage_list. Add _dl_tls_dtv_slotinfo_list, _dl_tls_static_nelem, and _dl_tls_generation. * include/stdlib.h: Declare __libc_memalign. * elf/Makefile: Add rules to build and run tst-tls4 and tst-tls5. * elf/tst-tls4.c: New file. * elf/tst-tls5.c: New file. * elf/tst-tlsmod2.c: New file. * elf/tls-macros.h: asms using ___tls_get_addr destroy %ecx and %edx. * elf/tst-tlsmod1.c: Don't define variables unles USE_TLS. * elf/tst-tls1.c: Use test-skeleton.c. * elf/tst-tls2.c: Likewise. * elf/tst-tls3.c: Likewise. * elf/dl-conflict.c (RESOLVE_MAP): Return NULL not 0. * sysdeps/mips/machine-gmon.h: Update MCOUNT for current GCC behavior. --- linuxthreads/ChangeLog | 7 ++++++- linuxthreads/sysdeps/i386/tls.h | 10 ++++++++-- 2 files changed, 14 insertions(+), 3 deletions(-) (limited to 'linuxthreads') diff --git a/linuxthreads/ChangeLog b/linuxthreads/ChangeLog index 79a3cce..fee9a7a 100644 --- a/linuxthreads/ChangeLog +++ b/linuxthreads/ChangeLog @@ -1,8 +1,13 @@ +2002-02-12 Ulrich Drepper + + * sysdeps/i386/tls.c (INSTALL_NEW_DTV): Define. + (INSTALL_DTV): Adjust for being passed pointer to element with length. + 2002-02-08 Ulrich Drepper * sysdeps/i386/tls.h (TLS_INIT_TP): Also initialize %gs. -2002-02-08 Richard Henderson +2002-02-08 Richard Henderson * sysdeps/alpha/elf/pt-initfini.c: Use \n\ for multiline string. diff --git a/linuxthreads/sysdeps/i386/tls.h b/linuxthreads/sysdeps/i386/tls.h index 79e4fde..8e1d469 100644 --- a/linuxthreads/sysdeps/i386/tls.h +++ b/linuxthreads/sysdeps/i386/tls.h @@ -67,9 +67,15 @@ typedef struct # define TLS_TCB_AT_TP 1 -/* Install the dtv pointer. */ +/* Install the dtv pointer.
