We have a variety of hurdles to overcome in doing this: 46 6635 ab196087 * 47 6635 ab196087 * - The size of system types can differ between ELFCLASS32 and 48 6635 ab196087 * ELFCLASS64. 49 6635 ab196087 * - Stucture layout can differ between architectures, so a given 50 6635 ab196087 * field can have a different struct offset than is native 51 6635 ab196087 * for the system running elfdump. Depending on the struct 52 6635 ab196087 * in question, the layout for one platform may be impossible 53 6635 ab196087 * to achieve on another. 54 6635 ab196087 * - The byte order of the core object can differ from that 55 6635 ab196087 * of the system running elfdump. 56 6635 ab196087 * 57 6635 ab196087 * The result is that in the fully general case, each architecture 58 6635 ab196087 * can have a slightly different definition of these structures. 59 6635 ab196087 * The usual approach of assigning a pointer of the desired structure 60 6635 ab196087 * type and then accessing fields through that pointer cannot be used 61 6635 ab196087 * here. That approach can only be used to access structures with the 62 6635 ab196087 * native layout of the elfdump host. We want any instance of elfdump 63 6635 ab196087 * to be able to examine a Solaris object for any supported architecture, 64 6635 ab196087 * so we need a more flexible approach. 65 6635 ab196087 * 66 6635 ab196087 * The solution to this problem lies in the fact that the binary 67 6635 ab196087 * layout of these public types cannot be changed, except in backward 68 6635 ab196087 * compatible ways. They are written to core files or published in 69 6635 ab196087 * other ways such that we can't make changes that would make it 70 6635 ab196087 * impossible to analyze old files. This means that we can build 71 6635 ab196087 * table of offsets and sizes for each field of each struct, on 72 6635 ab196087 * a per-archecture basis. These tables can be used to access the 73 6635 ab196087 * struct fields directly from the note desc data, and elfdump 74 6635 ab196087 * on any host can read the data from any other host. 75 6635 ab196087 * 76 6635 ab196087 * When reading these tables, it can be very helpful to examine 77 6635 ab196087 * the struct definition at the same time. 78 6635 ab196087 */ 79 6635 ab196087 80 6635 ab196087 /* 81 6635 ab196087 * sl_field_t is used to describe a struct field 82 6635 ab196087 */ 83 6635 ab196087 typedef struct { 84 6635 ab196087 ushort_t slf_offset; /* Offset from start of struct */ 85 6635 ab196087 ushort_t slf_eltlen; /* Size of datum, in bytes */ 86 6635 ab196087 ushort_t slf_nelts; /* 0 for scalar, # of els for array */ 87 6635 ab196087 uchar_t slf_sign; /* True (1) if signed quantity */ 88 6635 ab196087 } sl_field_t; 89 6635 ab196087 90 6635 ab196087 /* 91 6635 ab196087 * This type is used to extract and manipuate data described by 92 6635 ab196087 * sl_field_t.
