23 /* MS has stored all its debug information in a set of structures
24 * which has been rather consistent across the years (ie you can grasp
25 * some continuity, and not so many drastic changes).
27 * A bit of history on the various formats
28 * MSVC 1.0 PDB v1 (new format for debug info)
29 * MSVC 2.0 Inclusion in link of debug info (PDB v2)
30 * MSVC 5.0 Types are 24 bits (instead of 16 for <= 4.x)
31 * MSVC x.0 PDB (change in internal streams layout)
33 * .DBG Contains COFF, FPO and Codeview info
34 * .PDB New format for debug info (information is
35 * derived from Codeview information)
36 * VCx0.PDB x major MSVC number, stores types, while
37 * <project>.PDB stores symbols.
39 * Debug information can either be found in the debug section of a PE
40 * module (in something close to a .DBG file), or the debug section
41 * can actually refer to an external file, which can be in turn,
42 * either a .DBG or .PDB file.
44 * Regarding PDB files:
46 * They are implemented as a set of internal files (as a small file
47 * system). The file is split into blocks, an internal file is made
48 * of a set of blocks. Internal files are accessed through
49 * numbers. For example,
50 * 1/ is the ROOT (basic information on the file)
51 * 2/ is the Symbol information (global symbols, local variables...)
52 * 3/ is the Type internal file (each the symbols can have type
53 * information associated with it).
55 * Over the years, three formats existed for the PDB:
56 * - ?? was rather linked to 16 bit code (our support shall be rather
58 * - JG: it's the signature embedded in the file header. This format
59 * has been used in MSVC 2.0 => 5.0.
60 * - DS: it's the signature embedded in the file header. It's the
61 * current format supported my MS.
63 * Types internal stream
64 * ---------------------
65 * Types (from the Type internal file) have existed in three flavors
66 * (note that those flavors came as historical evolution, but there
67 * isn't a one to one link between types evolution and PDB formats'
69 * - the first flavor (suffixed by V1 in this file), where the types
70 * and subtypes are 16 bit entities; and where strings are in Pascal
71 * format (first char is their length and are not 0 terminated)
72 * - the second flavor (suffixed by V2) differs from first flavor with
73 * types and subtypes as 32 bit entities. This forced some
74 * reordering of fields in some types
75 * - the third flavor (suffixed by V3) differs from second flavor with
76 * strings stored as C strings (ie are 0 terminated, instead of
78 * The different flavors can coexist in the same file (is this really
81 * For the evolution of types, the need of the second flavor was the
82 * number of types to be defined (limited to 0xFFFF, including the C
83 * basic types); the need of the third flavor is the increase of
84 * symbol size (to be greater than 256), which was likely needed for
85 * complex C++ types (nested + templates).
87 * It's somehow difficult to represent the layout of those types on
89 * - some integral values are stored as numeric leaf, which size is
90 * variable depending on its value
92 * Symbols internal stream
93 * -----------------------
94 * Here also we find three flavors (that we've suffixed with _V1, _V2
95 * and _V3) even if their evolution is closer to the evolution of
96 * types, they are not completely linked together.
