30 /* minidump_format.h: A cross-platform reimplementation of minidump-related
31  * portions of DbgHelp.h from the Windows Platform SDK.
32  *
33  * (This is C99 source, please don't corrupt it with C++.)
34  *
35  * This file contains the necessary definitions to read minidump files
36  * produced on sparc. These files may be read on any platform provided
37  * that the alignments of these structures on the processing system are
38  * identical to the alignments of these structures on the producing system.
39  * For this reason, precise-sized types are used. The structures defined
40  * by this file have been laid out to minimize alignment problems by ensuring
41  * ensuring that all members are aligned on their natural boundaries. In
42  * In some cases, tail-padding may be significant when different ABIs specify
43  * different tail-padding behaviors. To avoid problems when reading or
44  * writing affected structures, MD_*_SIZE macros are provided where needed,
45  * containing the useful size of the structures without padding.
46  *
47  * Structures that are defined by Microsoft to contain a zero-length array
48  * are instead defined here to contain an array with one element, as
49  * zero-length arrays are forbidden by standard C and C++. In these cases,
50  * *_minsize constants are provided to be used in place of sizeof. For a
51  * cleaner interface to these sizes when using C++, see minidump_size.h.
52  *
53  * These structures are also sufficient to populate minidump files.
54  *
55  * These definitions may be extended to support handling minidump files
56  * for other CPUs and other operating systems.
57  *
58  * Because precise data type sizes are crucial for this implementation to
59  * function properly and portably in terms of interoperability with minidumps
60  * produced by DbgHelp on Windows, a set of primitive types with known sizes
61  * are used as the basis of each structure defined by this file. DbgHelp
62  * on Windows is assumed to be the reference implementation; this file
63  * seeks to provide a cross-platform compatible implementation. To avoid
64  * collisions with the types and values defined and used by DbgHelp in the
65  * event that this implementation is used on Windows, each type and value
66  * defined here is given a new name, beginning with "MD". Names of the
67  * equivalent types and values in the Windows Platform SDK are given in
68  * comments.
