-     1) 69% of the attributes used forms DW_FORM_addr, DW_FORM_data*,

-        DW_FORM_string, read_attribute simply hands back a pointer to
-        the null-terminated string in dwarf_info_buffer, so no dynamic
-        allocation is needed there either.
-
-     3) The remaining 1% of the attributes all used DW_FORM_block1.
-        75% of those were DW_AT_frame_base location lists for
-        functions; the rest were DW_AT_location attributes, probably
-        for the global variables.
-
-     Anyway, what this all means is that the memory the dwarf2
-     reader uses as temporary space reading partial symbols is about
-     0.5% as much as we use for dwarf_*_buffer.  That's noise.  */

-/* Read the initial length from a section.  The (draft) DWARF 3
-   specification allows the initial length to take up either 4 bytes
-   or 12 bytes.  If the first 4 bytes are 0xffffffff, then the next 8
-   bytes describe the length and all offsets will be 8 bytes in length
-   instead of 4.
-
-   An older, non-standard 64-bit format is also handled by this
-   function.  The older format in question stores the initial length
-   as an 8-byte quantity without an escape value.  Lengths greater
-   than 2^32 aren't very common which means that the initial 4 bytes
-   is almost always zero.  Since a length value of zero doesn't make
-   sense for the 32-bit format, this initial zero can be considered to
-   be an escape value which indicates the presence of the older 64-bit
-   format.  As written, the code can't detect (old format) lengths
-   greater than 4GB.  If it becomes necessary to handle lengths somewhat
-   larger than 4GB, we could allow other small values (such as the
-   non-sensical values of 1, 2, and 3) to also be used as escape values
-   indicating the presence of the old format.
-
-   The value returned via bytes_read should be used to increment
-   the relevant pointer after calling read_initial_length().
-   
-   As a side effect, this function sets the fields initial_length_size
-   and offset_size in cu_header to the values appropriate for the
-   length field.  (The format of the initial length field determines
-   the width of file offsets to be fetched later with fetch_offset().)
-   
-   [ Note:  read_initial_length() and read_offset() are based on the
-     document entitled "DWARF Debugging Information Format", revision
-     3, draft 8, dated November 19, 2001.  This document was obtained
-     from:
-
-	http://reality.sgiweb.org/davea/dwarf3-draft8-011125.pdf
-     
-     This document is only a draft and is subject to change.  (So beware.)
-
-     Details regarding the older, non-standard 64-bit format were
-     determined empirically by examining 64-bit ELF files produced
-     by the SGI toolchain on an IRIX 6.5 machine.

-   FIXME: Implement more operations as necessary.
-
-   A location description containing no operations indicates that the

-   those, the return value is meaningless.
-
-   When the result is a register number, the global isreg flag is set,

-
-   When the result is a base register offset, the global offreg flag is set
-   and the register number is returned in basereg, otherwise it is cleared.
-
-   When the DW_OP_fbreg operation is encountered without a corresponding
-   DW_AT_frame_base attribute, the global islocal flag is set.
-   Hopefully the machine dependent code knows how to set up a virtual
