/* 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
