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