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. * * Author: Julian Seward */ /* * ARM support */ #ifndef GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_ARM_H__ #define GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_ARM_H__ #define MD_FLOATINGSAVEAREA_ARM_FPR_COUNT … #define MD_FLOATINGSAVEAREA_ARM_FPEXTRA_COUNT … /* * Note that these structures *do not* map directly to the CONTEXT * structure defined in WinNT.h in the Windows Mobile SDK.
