51 * Descriptions:
52 *
53 * (hdr) IMAGE_SEPARATE_DEBUG_HEADER - .DBG-specific file header; holds info that
54 * applies to the file as a whole, including # of COFF sections, file offsets, etc.
55 * (hdr) IMAGE_SECTION_HEADER - list of COFF sections copied verbatim from .EXE;
56 * although this directory contains file offsets, these offsets are meaningless
57 * in the context of the .DBG file, because only the section headers are copied
58 * to the .DBG file... not the binary data it points to.
59 * (hdr) IMAGE_DEBUG_DIRECTORY - list of different formats of debug info contained in file
60 * (see IMAGE_DEBUG_TYPE_* descriptions below); tells where each section starts
61 * (hdr) OMFSignature (CV) - Contains "NBxx" signature, plus file offset telling how far
62 * into the IMAGE_DEBUG_TYPE_CODEVIEW section the OMFDirHeader and OMFDirEntry's sit
63 * (data) IMAGE_DEBUG_TYPE_MISC - usually holds name of original .EXE file
64 * (data) IMAGE_DEBUG_TYPE_FPO - Frame Pointer Optimization data; used for dealing with
65 * optimized stack frames (optional)
66 * (data) IMAGE_DEBUG_TYPE_CODEVIEW - *** THE GOOD STUFF ***
67 * This block of data contains all the symbol tables, line number info, etc.,
68 * that the Visual C++ debugger needs.
69 * (hdr) OMFDirHeader (CV) -
70 * (hdr) OMFDirEntry (CV) - list of subsections within CodeView debug data section
71 */
72
73 /*
74 * The .DBG file typically has three arrays of directory entries, which tell
75 * the OS or debugger where in the file to look for the actual data
76 *
77 * IMAGE_SECTION_HEADER - number of entries determined by:
78 * (IMAGE_SEPARATE_DEBUG_HEADER.NumberOfSections)

80 * IMAGE_DEBUG_DIRECTORY - number of entries determined by:
81 * (IMAGE_SEPARATE_DEBUG_HEADER.DebugDirectorySize / sizeof (IMAGE_DEBUG_DIRECTORY))
