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 ARM. 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 |
41 | * ensuring that all members are aligned on their natural boundaries. |
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 | * Because precise data type sizes are crucial for this implementation to |
56 | * function properly and portably, a set of primitive types with known sizes |
57 | * are used as the basis of each structure defined by this file. |
