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. + * + * Author: Neal Sidhwaney */ + + +/* + * Breakpad minidump extension for PPC64 support.
