/* MS has stored all its debug information in a set of structures

 * which has been rather consistent across the years (ie you can grasp

 * some continuity, and not so many drastic changes).

 *

 * A bit of history on the various formats

 *      MSVC 1.0        PDB v1 (new format for debug info)

 *      MSVC 2.0        Inclusion in link of debug info (PDB v2)

 *      MSVC 5.0        Types are 24 bits (instead of 16 for <= 4.x)

 *      MSVC x.0        PDB (change in internal streams layout)

 *

 *      .DBG            Contains COFF, FPO and Codeview info

 *      .PDB            New format for debug info (information is

 *                      derived from Codeview information)

 *      VCx0.PDB        x major MSVC number, stores types, while

 *                      <project>.PDB stores symbols.

 *

 * Debug information can either be found in the debug section of a PE

 * module (in something close to a .DBG file), or the debug section

 * can actually refer to an external file, which can be in turn,

 * either a .DBG or .PDB file.

 *

 * Regarding PDB files:

 * -------------------

 * They are implemented as a set of internal files (as a small file

 * system). The file is split into blocks, an internal file is made

 * of a set of blocks. Internal files are accessed through

 * numbers. For example,

 * 1/ is the ROOT (basic information on the file)

 * 2/ is the Symbol information (global symbols, local variables...)

 * 3/ is the Type internal file (each the symbols can have type

 * information associated with it).

 *

 * Over the years, three formats existed for the PDB:

 * - ?? was rather linked to 16 bit code (our support shall be rather

 *   bad)

 * - JG: it's the signature embedded in the file header. This format

 *   has been used in MSVC 2.0 => 5.0.

 * - DS: it's the signature embedded in the file header. It's the

 *   current format supported my MS.

 *

 * Types internal stream

 * ---------------------

 * Types (from the Type internal file) have existed in three flavors

 * (note that those flavors came as historical evolution, but there

 * isn't a one to one link between types evolution and PDB formats'

 * evolutions:

 * - the first flavor (suffixed by V1 in this file), where the types

 *   and subtypes are 16 bit entities; and where strings are in Pascal

 *   format (first char is their length and are not 0 terminated)

 * - the second flavor (suffixed by V2) differs from first flavor with

 *   types and subtypes as 32 bit entities. This forced some

 *   reordering of fields in some types

 * - the third flavor (suffixed by V3) differs from second flavor with

 *   strings stored as C strings (ie are 0 terminated, instead of

 *   length prefixed)

 * The different flavors can coexist in the same file (is this really

 * true ??)

 *

 * For the evolution of types, the need of the second flavor was the

 * number of types to be defined (limited to 0xFFFF, including the C

 * basic types); the need of the third flavor is the increase of

 * symbol size (to be greater than 256), which was likely needed for

 * complex C++ types (nested + templates).

 *

 * It's somehow difficult to represent the layout of those types on

 * disk because:

 * - some integral values are stored as numeric leaf, which size is

 *   variable depending on its value

 *

 * Symbols internal stream

 * -----------------------

 * Here also we find three flavors (that we've suffixed with _V1, _V2

 * and _V3) even if their evolution is closer to the evolution of

 * types, they are not completely linked together.

/*

 * This covers the basic datatypes that VC++ seems to be using these days.

 * 32 bit mode only.  There are additional numbers for the pointers in 16

 * bit mode.  There are many other types listed in the documents, but these

 * are apparently not used by the compiler, or represent pointer types

 * that are not used.

 *

 * Official MS documentation says that type (< 0x4000, so 12 bits) is made of:

 *        +----------+------+------+----------+------+

 *        |    11    | 10-8 | 7-4  |     3    | 2-0  |

 *        +----------+------+------+----------+------+

 *        | reserved | mode | type | reserved | size |

 *        +----------+------+------+----------+------+

 * In recent PDB files, type 8 exists, and is seen as an HRESULT... So we've

 * added this basic type... as if bit 3 had been integrated into the size field

 */
