Subject: Update.
2003-07-24 Ulrich Drepper <drepper@redhat.com>
* include/link.h (struct link_map): Add l_tls_firstbyte_offset field.
* sysdeps/generic/dl-tls.c [TLS_TCB_AT_TP] (_dl_determine_tlsoffset):
Fix calculation of offsets to take misalignment of first byte in
file into account.
* elf/dl-load.c (_dl_map_object_from_fd): Initialize
l_tls_firstbyte_offset field.
* elf/rtld.c (_dl_start_final, _dl_start, dl_main): Likewise.
* elf/dl-reloc.c (_dl_allocate_static_tls): Change return type to int.
Take l_tls_firstbyte_offset information into account.
(CHECK_STATIS_TLS): _dl_allocate_static_tls can fail now.
* sysdeps/generic/ldsodefs.h: Adjust _dl_allocate_static_tls prototype.
* elf/Makefile: Add rules to build and run tst-tls14.
* elf/tst-tls14.c: New file.
* elf/tst-tlsmod14a.c: New file.
* elf/tst-tlsmod14b.c: New file.
