Update.
2002-02-12 Ulrich Drepper <drepper@redhat.com>
* 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.
