Update.
2002-06-17  Jakub Jelinek  <jakub@redhat.com>

	* 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.

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).

2002-06-21  Ulrich Drepper  <drepper@redhat.com>

	* 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.

2002-06-05  Jakub Jelinek  <jakub@redhat.com>

	* libio/Makefile (tests): Add tst-mmap-setvbuf.
	* libio/tst-mmap-setvbuf.c: New test.
