+/* 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
