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 * ensuring that all members are aligned on their natural boundaries. In * 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. * * These definitions may be extended to support handling minidump files * for other CPUs and other operating systems. * * Because precise data type sizes are crucial for this implementation to * function properly and portably in terms of interoperability with minidumps * produced by DbgHelp on Windows, a set of primitive types with known sizes * are used as the basis of each structure defined by this file. DbgHelp * on Windows is assumed to be the reference implementation; this file * seeks to provide a cross-platform compatible implementation. To avoid * collisions with the types and values defined and used by DbgHelp in the * event that this implementation is used on Windows, each type and value * defined here is given a new name, beginning with "MD". Names of the * equivalent types and values in the Windows Platform SDK are given in * comments. * * Author: Mark Mentovai * Change to split into its own file: Neal Sidhwaney */ /* * SPARC support, see (solaris)sys/procfs_isa.h also */ #ifndef GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_SPARC_H__ #define GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_SPARC_H__ #define MD_FLOATINGSAVEAREA_SPARC_FPR_COUNT 32 typedef struct { /* FPU floating point regs */ uint64_t regs[MD_FLOATINGSAVEAREA_SPARC_FPR_COUNT]; uint64_t filler; uint64_t fsr; /* FPU status register */ } MDFloatingSaveAreaSPARC; /* FLOATING_SAVE_AREA */ #define MD_CONTEXT_SPARC_GPR_COUNT 32 typedef struct { /* The next field determines the layout of the structure, and which parts * of it are populated */ uint32_t context_flags; uint32_t flag_pad; /* * General register access (SPARC). * Don't confuse definitions here with definitions in . * Registers are 32 bits for ILP32, 64 bits for LP64. * SPARC V7/V8 is for 32bit, SPARC V9 is for 64bit */ /* 32 Integer working registers */ /* g_r[0-7] global registers(g0-g7) * g_r[8-15] out registers(o0-o7) * g_r[16-23] local registers(l0-l7) * g_r[24-31] in registers(i0-i7) */ uint64_t g_r[MD_CONTEXT_SPARC_GPR_COUNT]; /* several control registers */ /* Processor State register(PSR) for SPARC V7/V8 * Condition Code register (CCR) for SPARC V9 */ uint64_t ccr; uint64_t pc; /* Program Counter register (PC) */ uint64_t npc; /* Next Program Counter register (nPC) */ uint64_t y; /* Y register (Y) */ /* Address Space Identifier register (ASI) for SPARC V9 * WIM for SPARC V7/V8 */ uint64_t asi; /* Floating-Point Registers State register (FPRS) for SPARC V9 * TBR for for SPARC V7/V8 */ uint64_t fprs; /* The next field is included with MD_CONTEXT_SPARC_FLOATING_POINT */ MDFloatingSaveAreaSPARC float_save; } MDRawContextSPARC; /* CONTEXT_SPARC */ /* Indices into g_r for registers with a dedicated or conventional purpose. */ enum MDSPARCRegisterNumbers { MD_CONTEXT_SPARC_REG_SP = 14 }; /* For (MDRawContextSPARC).context_flags.
