members to the end, so a libpthread compiled with !USE_TLS will still find other members properly. * sysdeps/i386/i486/bits/string.h (__strcpy_g): Add dummy output operand for DEST memory. Fix dummy input operand to use SRC. Reported by Davin McCall <davmac@ozonline.com.au>. * sysdeps/generic/libc-tls.c (__libc_setup_tls): Account for TCB alignment when initializing the DTV entry. * elf/dl-load.c (_dl_map_object_from_fd): If we hit a TLS segment when TLS has not been set up, try to set it up if we can. * elf/tst-tls4.c: Revert last change. * elf/tst-tls5.c: Likewise. * elf/tst-tls6.c: Likewise. * elf/tst-tls7.c: Likewise. * elf/tst-tls8.c: Likewise. * elf/tst-tls9.c: Likewise. * sysdeps/generic/dl-tls.c [SHARED] (_dl_tls_setup): New function. * sysdeps/generic/ldsodefs.h: Declare it. * elf/Versions (ld: GLIBC_PRIVATE): Add it. * sysdeps/generic/libc-tls.c (init_slotinfo): New static inline function, broken out of __libc_setup_tls. (init_static_tls): Likewise. (__libc_setup_tls): Call them. (_dl_tls_setup): New function, uses new subroutines. * elf/dl-close.c (free_slotinfo): Make argument pointer to pointer. Clear the pointer when returning true. (libc_freeres_fn) [SHARED]: If GL(dl_initial_dtv) is null, free the first element of the slotinfo list too. * sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Define only if [SHARED]. * sysdeps/generic/ldsodefs.h (_dl_next_tls_modid): Declare as hidden. (_dl_determine_tlsoffset): Likewise. * elf/rtld.c (_dl_initial_error_catch_tsd): Renamed from startup_error_tsd, made global. (dl_main): Update initialization. * elf/dl-tsd.c: Likewise. * sysdeps/generic/ldsodefs.h: Declare it.
