  29. /* minidump_format.h: A cross-platform reimplementation of minidump-related
  30. * portions of DbgHelp.h from the Windows Platform SDK.
  31. *
  32. * (This is C99 source, please don't corrupt it with C++.)
  33. *
  34. * This file contains the necessary definitions to read minidump files
  35. * produced on ppc64. These files may be read on any platform provided
  36. * that the alignments of these structures on the processing system are
  37. * identical to the alignments of these structures on the producing system.
  38. * For this reason, precise-sized types are used. The structures defined
  39. * by this file have been laid out to minimize alignment problems by ensuring
  40. * ensuring that all members are aligned on their natural boundaries. In
  41. * In some cases, tail-padding may be significant when different ABIs specify
  42. * different tail-padding behaviors. To avoid problems when reading or
  43. * writing affected structures, MD_*_SIZE macros are provided where needed,
  44. * containing the useful size of the structures without padding.
  45. *
  46. * Structures that are defined by Microsoft to contain a zero-length array
  47. * are instead defined here to contain an array with one element, as
  48. * zero-length arrays are forbidden by standard C and C++. In these cases,
  49. * *_minsize constants are provided to be used in place of sizeof. For a
  50. * cleaner interface to these sizes when using C++, see minidump_size.h.
  51. *
  52. * These structures are also sufficient to populate minidump files.
  53. *
  54. * These definitions may be extended to support handling minidump files
  55. * for other CPUs and other operating systems.
  56. *
  57. * Because precise data type sizes are crucial for this implementation to
  58. * function properly and portably in terms of interoperability with minidumps
  59. * produced by DbgHelp on Windows, a set of primitive types with known sizes
  60. * are used as the basis of each structure defined by this file. DbgHelp
  61. * on Windows is assumed to be the reference implementation; this file
  62. * seeks to provide a cross-platform compatible implementation. To avoid
  63. * collisions with the types and values defined and used by DbgHelp in the
  64. * event that this implementation is used on Windows, each type and value
  65. * defined here is given a new name, beginning with "MD". Names of the
  66. * equivalent types and values in the Windows Platform SDK are given in
  67. * comments.
