| /* minidump_format.h: A cross-platform reimplementation of minidump-related |
| * portions of DbgHelp.h from the Windows Platform SDK. |
| * |
| * (This is C99 source, please don't corrupt it with C++.) |
| * |
| * This file contains the necessary definitions to read minidump files |
| * produced on ARM. These files may be read on any platform provided |
| * that the alignments of these structures on the processing system are |
| * identical to the alignments of these structures on the producing system. |
| * For this reason, precise-sized types are used. The structures defined |
| * by this file have been laid out to minimize alignment problems by |
| * ensuring that all members are aligned on their natural boundaries. |
| * In some cases, tail-padding may be significant when different ABIs specify |
| * different tail-padding behaviors. To avoid problems when reading or |
| * writing affected structures, MD_*_SIZE macros are provided where needed, |
| * containing the useful size of the structures without padding. |
| * |
| * Structures that are defined by Microsoft to contain a zero-length array |
| * are instead defined here to contain an array with one element, as |
| * zero-length arrays are forbidden by standard C and C++. In these cases, |
| * *_minsize constants are provided to be used in place of sizeof. For a |
| * cleaner interface to these sizes when using C++, see minidump_size.h. |
| * |
| * These structures are also sufficient to populate minidump files. |
| * |
| * Because precise data type sizes are crucial for this implementation to |
| * function properly and portably, a set of primitive types with known sizes |
| * are used as the basis of each structure defined by this file. |
