-+/* The mapped index file format is designed to be directly mmap()able
-+ on any architecture. In most cases, a datum is represented using a
-+ little-endian 32-bit integer value, called an offset_type. Big
-+ endian machines must byte-swap the values before using them.
-+ Exceptions to this rule are noted. The data is laid out such that
-+ alignment is always respected.
-+
-+ A mapped index consists of several sections.
-+
-+ 1. The file header. This is a sequence of values, of offset_type
-+ unless otherwise noted:
-+ [0] The version number. Currently 1.
-+ [1] The offset, from the start of the file, of the CU list.
-+ [2] The offset, from the start of the file, of the address section.
-+ [3] The offset, from the start of the file, of the symbol table.
-+ [4] The offset, from the start of the file, of the constant pool.
-+
-+ 2. The CU list. This is a sequence of pairs of 64-bit
-+ little-endian values. The first element in each pair is the offset
-+ of a CU in the .debug_info section. The second element in each
-+ pair is the length of that CU. References to a CU elsewhere in the
-+ map are done using a CU index, which is just the 0-based index into
-+ this table.
-+
-+ 3. The address section. The address section consists of a sequence
-+ of address entries. Each address entry has three elements.
-+ [0] The low address. This is a 64-bit little-endian value.
-+ [1] The high address. This is a 64-bit little-endian value.
-+ [2] The CU index. This is an offset_type value.
-+
-+ 4. The symbol table. This is a hash table. The size of the hash
-+ table is always a power of 2. The initial hash and the step are
-+ currently defined by the `find_slot' function.
-+
-+ Each slot in the hash table consists of a pair of offset_type
-+ values. The first value is the offset of the symbol's name in the
-+ constant pool. The second value is the offset of the CU vector in
-+ the constant pool.
-+
-+ If both values are 0, then this slot in the hash table is empty.
-+ This is ok because while 0 is a valid constant pool index, it
-+ cannot be a valid index for both a string and a CU vector.
-+
-+ A string in the constant pool is stored as a \0-terminated string,
-+ as you'd expect.
-+
-+ A CU vector in the constant pool is a sequence of offset_type
-+ values. The first value is the number of CU indices in the vector.
-+ Each subsequent value is the index of a CU in the CU list. This
-+ element in the hash table is used to indicate which CUs define the
-+ symbol.
-+
-+ 5. The constant pool. This is simply a bunch of bytes. It is
-+ organized so that alignment is correct: CU vectors are stored
-+ first, followed by strings. */
