/* 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 ARM. 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 that all members are aligned on their natural boundaries.
|
|
* 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.
|
|
*
|
|
* Because precise data type sizes are crucial for this implementation to
|
|
* function properly and portably, a set of primitive types with known sizes
|
|
* are used as the basis of each structure defined by this file.
