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.
