* elf/dl-lookup.c (_dl_debug_bindings): Use type_class 4 for TLS
lookups.
* elf/rtld.c (dl_main): Move TLS setup code before LD_TRACE_PRELINKING
code. Print TLS modid and offset for modules containing PT_TLS
segments.

* sysdeps/unix/sysv/linux/i386/dl-brk.c: Move...
* sysdeps/unix/sysv/linux/dl-brk.c: ...here.
* sysdeps/unix/sysv/linux/i386/dl-sbrk.c: Move...
* sysdeps/unix/sysv/linux/dl-sbrk.c: ...here.
2002-06-07 Jakub Jelinek <jakub@redhat.com>
* nss/getXXbyYY_r.c (NEW, NEW1): Define.
(NEW (REENTRANT_NAME)): Strong alias to INTERNAL (REENTRANT_NAME).
(REENTRANT_NAME@@GLIBC_2.1.2): Use NEW (REENTRANT_NAME).
* nss/getXXent_r.c (NEW, NEW1): Define.
(NEW (REENTRANT_GETNAME)): Strong alias to
INTERNAL (REENTRANT_GETNAME).
(REENTRANT_GETNAME@@GLIBC_2.1.2): Use NEW (REENTRANT_GETNAME).

* libio/fileops.c (_IO_file_setbuf_mmap): New function.
(_IO_file_jumps_mmap): Use it.
* libio/iosetvbuf.c: Don't call _IO_WSETBUF.
* libio/libioP.h: Remove _IO_wdefault_setbuf and
_IO_wdefault_setbuf_internal prorotypes. Add _IO_file_setbuf_mmap
prototype.
* libio/wfileops.c (_IO_wfile_setbuf): Removed.
(_IO_wfile_jumps_mmap): Don't use it anymore.
* libio/wgenops.c (_IO_wdefault_setbuf): Removed.
* libio/memstream.c (_IO_wmem_jumps): Use _IO_default_setbuf not
_IO_wdefault_setbuf.
* libio/vswprintf.c (_IO_wstrn_jumps): Likewise.
* libio/wstrops.c (_IO_wstr_jumps): Likewise.
* stdio-common/vfprintf.c (_IO_helper_jumps): Likewise.
