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 */ #ifndef GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_AMD64_H__ #define GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_AMD64_H__ /* * AMD64 support, see WINNT.H */ typedef struct { u_int16_t control_word; u_int16_t status_word; u_int8_t tag_word; u_int8_t reserved1; u_int16_t error_opcode; u_int32_t error_offset; u_int16_t error_selector; u_int16_t reserved2; u_int32_t data_offset; u_int16_t data_selector; u_int16_t reserved3; u_int32_t mx_csr; u_int32_t mx_csr_mask; u_int128_t float_registers[8]; u_int128_t xmm_registers[16]; u_int8_t reserved4[96]; } MDXmmSaveArea32AMD64; /* XMM_SAVE_AREA32 */ #define MD_CONTEXT_AMD64_VR_COUNT 26 typedef struct { /* * Register parameter home addresses. */ u_int64_t p1_home; u_int64_t p2_home; u_int64_t p3_home; u_int64_t p4_home; u_int64_t p5_home; u_int64_t p6_home; /* The next field determines the layout of the structure, and which parts * of it are populated */ u_int32_t context_flags; u_int32_t mx_csr; /* The next register is included with MD_CONTEXT_AMD64_CONTROL */ u_int16_t cs; /* The next 4 registers are included with MD_CONTEXT_AMD64_SEGMENTS */ u_int16_t ds; u_int16_t es; u_int16_t fs; u_int16_t gs; /* The next 2 registers are included with MD_CONTEXT_AMD64_CONTROL */ u_int16_t ss; u_int32_t eflags; /* The next 6 registers are included with MD_CONTEXT_AMD64_DEBUG_REGISTERS */ u_int64_t dr0; u_int64_t dr1; u_int64_t dr2; u_int64_t dr3; u_int64_t dr6; u_int64_t dr7; /* The next 4 registers are included with MD_CONTEXT_AMD64_INTEGER */ u_int64_t rax; u_int64_t rcx; u_int64_t rdx; u_int64_t rbx; /* The next register is included with MD_CONTEXT_AMD64_CONTROL */ u_int64_t rsp; /* The next 11 registers are included with MD_CONTEXT_AMD64_INTEGER */ u_int64_t rbp; u_int64_t rsi; u_int64_t rdi; u_int64_t r8; u_int64_t r9; u_int64_t r10; u_int64_t r11; u_int64_t r12; u_int64_t r13; u_int64_t r14; u_int64_t r15; /* The next register is included with MD_CONTEXT_AMD64_CONTROL */ u_int64_t rip; /* The next set of registers are included with * MD_CONTEXT_AMD64_FLOATING_POINT */ union { MDXmmSaveArea32AMD64 flt_save; struct { u_int128_t header[2]; u_int128_t legacy[8]; u_int128_t xmm0; u_int128_t xmm1; u_int128_t xmm2; u_int128_t xmm3; u_int128_t xmm4; u_int128_t xmm5; u_int128_t xmm6; u_int128_t xmm7; u_int128_t xmm8; u_int128_t xmm9; u_int128_t xmm10; u_int128_t xmm11; u_int128_t xmm12; u_int128_t xmm13; u_int128_t xmm14; u_int128_t xmm15; } sse_registers; }; u_int128_t vector_register[MD_CONTEXT_AMD64_VR_COUNT]; u_int64_t vector_control; /* The next 5 registers are included with MD_CONTEXT_AMD64_DEBUG_REGISTERS */ u_int64_t debug_control; u_int64_t last_branch_to_rip; u_int64_t last_branch_from_rip; u_int64_t last_exception_to_rip; u_int64_t last_exception_from_rip; } MDRawContextAMD64; /* CONTEXT */ /* For (MDRawContextAMD64).context_flags.
