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: Colin Blundell + */ + +/* + * ARM64 support + */ + +#ifndef GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_ARM64_H__ +#define GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_ARM64_H__ + +#include "google_breakpad/common/breakpad_types.h" + +#define MD_FLOATINGSAVEAREA_ARM64_FPR_COUNT 32 +#define MD_CONTEXT_ARM64_GPR_COUNT 33 + +typedef struct { + /* 32 128-bit floating point registers, d0 .. d31. */ + uint128_struct regs[MD_FLOATINGSAVEAREA_ARM64_FPR_COUNT]; + + uint32_t fpcr; /* FPU control register */ + uint32_t fpsr; /* FPU status register */ +} MDFloatingSaveAreaARM64; + +/* For (MDRawContextARM64).context_flags.
