-FIXME: Do we need to generate dependencies in partial symtabs?
-(Perhaps we don't need to).
-
-FIXME: Resolve minor differences between what information we put in the
-partial symbol table and what dbxread puts in.  For example, we don't yet
-put enum constants there.  And dbxread seems to invent a lot of typedefs
-we never see.  Use the new printpsym command to see the partial symbol table
-contents.
-
-FIXME: Figure out a better way to tell gdb about the name of the function
-contain the user's entry point (I.E. main())
-
-FIXME: See other FIXME's and "ifdef 0" scattered throughout the code for
-other things to work on, if you get bored. :-)

-   In order to make it easier to randomly access the attribute fields

-
-   Originally this was done using a simple but expensive algorithm, with an
-   array of unsorted structures, each containing an offset/type-pointer pair.
-   This array was scanned linearly each time a lookup was done.  The result

-   array of pointers looking for a structure that had the right offset member.
-
-   The second attempt used the same array of structures, but the array was
-   sorted using qsort each time a new offset/type was recorded, and a binary
-   search was used to find the type pointer for a given DIE offset.  This was
-   even slower, due to the overhead of sorting the array each time a new
-   offset/type pair was entered.
-
-   The third attempt uses a fixed size array of type pointers, indexed by a
-   value derived from the DIE offset.  Since the minimum DIE size is 4 bytes,
-   we can divide any DIE offset by 4 to obtain a unique index into this fixed
-   size array.  Since each element is a 4 byte pointer, it takes exactly as
-   much memory to hold this array as to hold the DWARF info for a given
-   compilation unit.  But it gets freed as soon as we are done with it.
-   This has worked well in practice, as a reasonable tradeoff between memory

-DESCRIPTION
-
-	DWARF version 1 doesn't supply any fundamental type information,

-	fundamental types that it knows how to construct, which is the
-	union of all types that it knows how to construct for all languages
-	that it knows about.  These are enumerated in gdbtypes.h.
-
-	As an example, assume we find a DIE that references a DWARF
-	fundamental type of FT_integer.  We first look in the ftypes
-	array to see if we already have such a type, indexed by the
-	gdb internal value of FT_INTEGER.  If so, we simply return a
-	pointer to that type.  If not, then we ask an appropriate
-	language dependent routine to create a type FT_INTEGER, using
-	defaults reasonable for the current target machine, and install
-	that type in ftypes for future reference.
-

-
-DESCRIPTION
-
-	The array subscripts and the data type of the elements of an
-	array are described by a list of data items, stored as a block
-	of contiguous bytes.  There is a data item describing each array
-	dimension, and a final data item describing the element type.
-	The data items are ordered the same as their appearance in the
-	source (I.E. leftmost dimension first, next to leftmost second,
-	etc).
-
-	The data items describing each array dimension consist of four
-	parts: (1) a format specifier, (2) type type of the subscript
-	index, (3) a description of the low bound of the array dimension,
-	and (4) a description of the high bound of the array dimension.
-
-	The last data item is the description of the type of each of
-	the array elements.
-
-	We are passed a pointer to the start of the block of bytes
-	containing the remaining data items, and a pointer to the first
-	byte past the data.  This function recursively decodes the
-	remaining data items and returns a type.
-
-	If we somehow fail to decode some data, we complain about it
-	and return a type "array of int".
-
-BUGS
-	FIXME:  This code only implements the forms currently used
-	by the AT&T and GNU C compilers.
-
-	The end pointer is supplied for error checking, maybe we should
-	use it for that...

-	decode_line_numbers -- decode a line number table fragment
-
-SYNOPSIS
-
-	static void decode_line_numbers (char *tblscan, char *tblend,
-		long length, long base, long line, long pc)
-
-DESCRIPTION
-
-	Translate the DWARF line number information to gdb form.
-
-	The ".line" section contains one or more line number tables, one for
-	each ".line" section from the objects that were linked.
-
-	The AT_stmt_list attribute for each TAG_source_file entry in the
-	".debug" section contains the offset into the ".line" section for the
-	start of the table for that file.
-
-	The table itself has the following structure:
-
-	<table length><base address><source statement entry>
-	4 bytes       4 bytes       10 bytes
-
-	The table length is the total size of the table, including the 4 bytes
-	for the length information.
-
-	The base address is the address of the first instruction generated
-	for the source file.
-
-	Each source statement entry has the following structure:
-
-	<line number><statement position><address delta>
-	4 bytes      2 bytes             4 bytes
-
-	The line number is relative to the start of the file, starting with
-	line 1.
-
-	The statement position either -1 (0xFFFF) or the number of characters
-	from the beginning of the line to the beginning of the statement.
-
-	The address delta is the difference between the base address and
-	the address of the first instruction for the statement.
-
-	Note that we must copy the bytes from the packed table to our local
-	variables before attempting to use them, to avoid alignment problems
-	on some machines, particularly RISC processors.
-
-BUGS
-
-	Does gdb expect the line numbers to be sorted?  They are now by
-	chance/luck, but are not required to be.  (FIXME)
-
-	The line with number 0 is unused, gdb apparently can discover the
-	span of the last line some other way. How?  (FIXME)

-	locval -- compute the value of a location attribute
-
-SYNOPSIS
-
-	static int locval (struct dieinfo *dip)
-
-DESCRIPTION
-
-	Given pointer to a string of bytes that define a location, compute
-	the location and return the value.
-	A location description containing no atoms indicates that the
-	object is optimized out. The optimized_out flag is set for those,
-	the return value is meaningless.
-
-	When computing values involving the current value of the frame pointer,
-	the value zero is used, which results in a value relative to the frame
-	pointer, rather than the absolute value.  This is what GDB wants
-	anyway.
-    
-	When the result is a register number, the isreg flag is set, otherwise
-	it is cleared.  This is a kludge until we figure out a better
-	way to handle the problem.  Gdb's design does not mesh well with the
-	DWARF notion of a location computing interpreter, which is a shame
-	because the flexibility goes unused.
-
-NOTES
-
-	Note that stack[0] is unused except as a default error return.

-LOCAL FUNCTION
-
-	scan_compilation_units -- build a psymtab entry for each compilation
-
-DESCRIPTION
-
-	This is the top level dwarf parsing routine for building partial
-	symbol tables.
-
-	It scans from the beginning of the DWARF table looking for the first
-	TAG_compile_unit DIE, and then follows the sibling chain to locate
-	each additional TAG_compile_unit DIE.
-   
-	For each TAG_compile_unit DIE it creates a partial symtab structure,
-	calls a subordinate routine to collect all the compilation unit's
-	global DIE's, file scope DIEs, typedef DIEs, etc, and then links the
-	new partial symtab structure into the partial symbol table.  It also
-	records the appropriate information in the partial symbol table entry
-	to allow the chunk of DIE's and line number table for this compilation
-	unit to be located and re-read later, to generate a complete symbol
-	table entry for the compilation unit.
-
-	Thus it effectively partitions up a chunk of DIE's for multiple
-	compilation units into smaller DIE chunks and line number tables,
-	and associates them with a partial symbol table entry.
-
-NOTES
-
-	If any compilation unit has no line number table associated with
-	it for some reason (a missing at_stmt_list attribute, rather than
-	just one with a value of zero, which is valid) then we ensure that
-	the recorded file offset is zero so that the routine which later
-	reads line number table fragments knows that there is no fragment
-	to read.
-
-RETURNS
-
-	Returns no value.

-
-SYNOPSIS
-
-	void basicdieinfo (char *diep, struct dieinfo *dip,
-			   struct objfile *objfile)
-
-DESCRIPTION
-
-	Given a pointer to raw DIE data, and a pointer to an instance of a
-	die info structure, this function extracts the basic information
-	from the DIE data required to continue processing this DIE, along
-	with some bookkeeping information about the DIE.
-
-	The information we absolutely must have includes the DIE tag,
-	and the DIE length.  If we need the sibling reference, then we
-	will have to call completedieinfo() to process all the remaining
-	DIE information.
-
-	Note that since there is no guarantee that the data is properly
-	aligned in memory for the type of access required (indirection
-	through anything other than a char pointer), and there is no
-	guarantee that it is in the same byte order as the gdb host,
-	we call a function which deals with both alignment and byte
-	swapping issues.  Possibly inefficient, but quite portable.
-
-	We also take care of some other basic things at this point, such
-	as ensuring that the instance of the die info structure starts
-	out completely zero'd and that curdie is initialized for use
-	in error reporting if we have a problem with the current die.
-
-NOTES
-
-	All DIE's must have at least a valid length, thus the minimum
-	DIE size is SIZEOF_DIE_LENGTH.  In order to have a valid tag, the
-	DIE size must be at least SIZEOF_DIE_TAG larger, otherwise they
-	are forced to be TAG_padding DIES.
-
-	Padding DIES must be at least SIZEOF_DIE_LENGTH in length, implying
-	that if a padding DIE is used for alignment and the amount needed is
-	less than SIZEOF_DIE_LENGTH, then the padding DIE has to be big
-	enough to align to the next alignment boundry.
-
-	We do some basic sanity checking here, such as verifying that the
-	length of the die would not cause it to overrun the recorded end of
-	the buffer holding the DIE info.  If we find a DIE that is either
-	too small or too large, we force it's length to zero which should
-	cause the caller to take appropriate action.
