 /* 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 ppc64.  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
  * ensuring that all members are aligned on their natural boundaries.  In
  * 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.
  *
  * These definitions may be extended to support handling minidump files
  * for other CPUs and other operating systems.
  *
  * Because precise data type sizes are crucial for this implementation to
  * function properly and portably in terms of interoperability with minidumps
  * produced by DbgHelp on Windows, a set of primitive types with known sizes
  * are used as the basis of each structure defined by this file.  DbgHelp
  * on Windows is assumed to be the reference implementation; this file
  * seeks to provide a cross-platform compatible implementation.  To avoid
  * collisions with the types and values defined and used by DbgHelp in the
  * event that this implementation is used on Windows, each type and value
  * defined here is given a new name, beginning with "MD".  Names of the
  * equivalent types and values in the Windows Platform SDK are given in
  * comments.
