* sysdeps/generic/libc-tls.c (__libc_setup_tls): Cope with zero ALIGN.
* malloc/hooks.c [_LIBC && (USE___THREAD || (USE_TLS && !SHARED))] (malloc_starter, memalign_starter, free_starter): Don't define these. * malloc/malloc.c [_LIBC && (USE___THREAD || (USE_TLS && !SHARED))]: Don't declare them either. * malloc/arena.c (ptmalloc_init) [_LIBC && USE_TLS]: Don't call __pthread_initialize, so no need to set hooks to *_starter. (ptmalloc_init_minimal): New function, broken out of ptmalloc_init. [_LIBC && SHARED && USE_TLS && !USE___THREAD] (__libc_malloc_pthread_startup): New function. * malloc/Versions (libc: GLIBC_PRIVATE): New set, add that function. * malloc/hooks.c (memalign_starter): New function. * malloc/malloc.c: Declare it. * malloc/arena.c (save_memalign_hook): New variable. (ptmalloc_init): Set __memalign_hook to memalign_starter. * elf/dl-minimal.c (free): Clear the memory. (calloc): Just call malloc, knowing all memory it returns is cleared. * sysdeps/generic/dl-tls.c (allocate_dtv): Use calloc instead of malloc and memset; calloc can avoid the zeroing when redundant. (_dl_tls_setup): Likewise. * elf/dl-load.c (decompose_rpath): Likewise. * sysdeps/generic/libc-tls.c (__libc_setup_tls): Comment out memset call, since memory from sbrk at startup is already zero. * elf/rtld.c (_dl_start, dl_main): TLS_INIT_TP macro now returns an error string for failure, null for success. Update callers. * sysdeps/generic/libc-tls.c (__libc_setup_tls): Likewise. * elf/dl-load.c (_dl_map_object_from_fd): Likewise.
