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 ensuring 41 * ensuring that all members are aligned on their natural boundaries. In 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 * These definitions may be extended to support handling minidump files 56 * for other CPUs and other operating systems. 57 * 58 * Because precise data type sizes are crucial for this implementation to 59 * function properly and portably in terms of interoperability with minidumps 60 * produced by DbgHelp on Windows, a set of primitive types with known sizes 61 * are used as the basis of each structure defined by this file. DbgHelp 62 * on Windows is assumed to be the reference implementation; this file 63 * seeks to provide a cross-platform compatible implementation. To avoid 64 * collisions with the types and values defined and used by DbgHelp in the 65 * event that this implementation is used on Windows, each type and value 66 * defined here is given a new name, beginning with "MD". Names of the 67 * equivalent types and values in the Windows Platform SDK are given in 68 * comments. 69 * 70 * Author: Mark Mentovai 71 * Change to split into its own file: Neal Sidhwaney */ 72 73 /* 74 * SPARC support, see (solaris)sys/procfs_isa.h also 75 */ 76 77 #ifndef GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_SPARC_H__ 78 #define GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_SPARC_H__ 79 80 #define MD_FLOATINGSAVEAREA_SPARC_FPR_COUNT 32 81 82 typedef struct { 83 84 /* FPU floating point regs */ 85 uint64_t regs[MD_FLOATINGSAVEAREA_SPARC_FPR_COUNT]; 86 87 uint64_t filler; 88 uint64_t fsr; /* FPU status register */ 89 } MDFloatingSaveAreaSPARC; /* FLOATING_SAVE_AREA */ 90 91 #define MD_CONTEXT_SPARC_GPR_COUNT 32 92 93 typedef struct { 94 /* The next field determines the layout of the structure, and which parts 95 * of it are populated 96 */ 97 uint32_t context_flags; 98 uint32_t flag_pad; 99 /* 100 * General register access (SPARC). 101 * Don't confuse definitions here with definitions in <sys/regset.h>. 102 * Registers are 32 bits for ILP32, 64 bits for LP64. 103 * SPARC V7/V8 is for 32bit, SPARC V9 is for 64bit 104 */ 105 106 /* 32 Integer working registers */ 107 108 /* g_r[0-7] global registers(g0-g7) 109 * g_r[8-15] out registers(o0-o7) 110 * g_r[16-23] local registers(l0-l7) 111 * g_r[24-31] in registers(i0-i7) 112 */ 113 uint64_t g_r[MD_CONTEXT_SPARC_GPR_COUNT]; 114 115 /* several control registers */ 116 117 /* Processor State register(PSR) for SPARC V7/V8 118 * Condition Code register (CCR) for SPARC V9 119 */ 120 uint64_t ccr; 121 122 uint64_t pc; /* Program Counter register (PC) */ 123 uint64_t npc; /* Next Program Counter register (nPC) */ 124 uint64_t y; /* Y register (Y) */ 125 126 /* Address Space Identifier register (ASI) for SPARC V9 127 * WIM for SPARC V7/V8 128 */ 129 uint64_t asi; 130 131 /* Floating-Point Registers State register (FPRS) for SPARC V9 132 * TBR for for SPARC V7/V8 133 */ 134 uint64_t fprs; 135 136 /* The next field is included with MD_CONTEXT_SPARC_FLOATING_POINT */ 137 MDFloatingSaveAreaSPARC float_save; 138 139 } MDRawContextSPARC; /* CONTEXT_SPARC */ 140 141 /* For (MDRawContextSPARC).context_flags.
