Update.

1998-08-09  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/Makefile [subdir=elf]: Add new files split out of
	dl-machine.h.
	* sysdeps/powerpc/dl-machine.c: New file.
	* sysdeps/powerpc/dl-machine.h: Move much stuff into separate
	files.  Revise ELF_PREFERRED_ADDRESS to take account of
	the new mapping information (fixes bug involving huge bloated
	web browser).  Set ELF_MACHINE_PLTREL_OVERLAP.
	* sysdeps/powerpc/dl-start.S: New file.

	* elf/dl-load.c (_dl_map_object_from_fd): Initialise l_map_start,
	l_map_end.
	* elf/do-rel.h: Call elf_machine_rel only once (to save space).
	* elf/dynamic-link.h: Allow PLT relocs to be in the middle of the
	others.  Call elf_dynamic_do_##reloc only once (to save even more
	space).
	* elf/link.h: Add new members l_map_start and l_map_end to keep
	track of the memory map.
	* elf/rtld.c (_dl_start): Initialise l_map_start for ld.so and
	the executable.

1998-09-01 11:53  Ulrich Drepper  <drepper@cygnus.com>

	* debug/Makefile (catchsegv): We need not rewrite SOVER anymore.
	Reported by Andreas Jaeger.

	* posix/glob.h: Use __size_t instead of size_t in definitions and
	make sure this is defined.

	* manual/locale.texi: Almost complete rewrite.  Document more functions

 /* Argp example #3 -- a program with options and arguments using argp */
 
+/* This program uses the same features as example 2, and uses options and
+   arguments.
+
+   We now use the first four fields in ARGP, so here's a description of them:
+     OPTIONS  -- A pointer to a vector of struct argp_option (see below)
+     PARSER   -- A function to parse a single option, called by argp
+     ARGS_DOC -- A string describing how the non-option arguments should look
+     DOC      -- A descriptive string about this program; if it contains a
+                 vertical tab character (\v), the part after it will be
+                 printed *following* the options
+
+   The function PARSER takes the following arguments:
+     KEY  -- An integer specifying which option this is (taken
+             from the KEY field in each struct argp_option), or
+             a special key specifying something else; the only
+             special keys we use here are ARGP_KEY_ARG, meaning
+             a non-option argument, and ARGP_KEY_END, meaning
+             that all argumens have been parsed
+     ARG  -- For an option KEY, the string value of its
+             argument, or NULL if it has none
+     STATE-- A pointer to a struct argp_state, containing
+             various useful information about the parsing state; used here
+             are the INPUT field, which reflects the INPUT argument to
+             argp_parse, and the ARG_NUM field, which is the number of the
+             current non-option argument being parsed
+   It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
+   given KEY wasn't recognized, or an errno value indicating some other
+   error.
+
+   Note that in this example, main uses a structure to communicate with the
+   parse_opt function, a pointer to which it passes in the INPUT argument to
+   argp_parse.  Of course, it's also possible to use global variables
+   instead, but this is somewhat more flexible.
+
+   The OPTIONS field contains a pointer to a vector of struct argp_option's;
+   that structure has the following fields (if you assign your option
+   structures using array initialization like this example, unspecified
+   fields will be defaulted to 0, and need not be specified):
+     NAME   -- The name of this option's long option (may be zero)
+     KEY    -- The KEY to pass to the PARSER function when parsing this option,
+               *and* the name of this option's short option, if it is a
+               printable ascii character
+     ARG    -- The name of this option's argument, if any
+     FLAGS  -- Flags describing this option; some of them are:
+                 OPTION_ARG_OPTIONAL -- The argument to this option is optional
+                 OPTION_ALIAS        -- This option is an alias for the
+                                        previous option
+                 OPTION_HIDDEN       -- Don't show this option in --help output
+     DOC    -- A documentation string for this option, shown in --help output
+
+   An options vector should be terminated by an option with all fields zero. */
