Typedefs | |
typedef int(* | llvm::X86Disassembler::byteReader_t )(const void *arg, uint8_t *byte, uint64_t address) |
Type for the byte reader that the consumer must provide to the decoder. Reads a single byte from the instruction's address space. | |
typedef void(* | llvm::X86Disassembler::dlog_t )(void *arg, const char *log) |
Type for the logging function that the consumer can provide to get debugging output from the decoder. | |
Enumerations | |
enum | llvm::X86Disassembler::EABase { llvm::X86Disassembler::EA_BASE_NONE } |
All possible values of the base field for effective-address computations, a.k.a. the Mod and R/M fields of the ModR/M byte. We distinguish between bases (EA_BASE_*) and registers that just happen to be referred to when Mod == 0b11 (EA_REG_*). More... | |
enum | llvm::X86Disassembler::SIBIndex { llvm::X86Disassembler::SIB_INDEX_NONE } |
All possible values of the SIB index field. borrows entries from ALL_EA_BASES with the special case that sib is synonymous with NONE. Vector SIB: index can be XMM or YMM. More... | |
enum | llvm::X86Disassembler::SIBBase { llvm::X86Disassembler::SIB_BASE_NONE } |
All possible values of the SIB base field. More... | |

Possible displacement types for effective-address computations. More... | |
enum | llvm::X86Disassembler::Reg |
All possible values of the reg field in the ModR/M byte. More... | |
enum | llvm::X86Disassembler::SegmentOverride { llvm::X86Disassembler::SEG_OVERRIDE_NONE, llvm::X86Disassembler::SEG_OVERRIDE_CS, llvm::X86Disassembler::SEG_OVERRIDE_SS, llvm::X86Disassembler::SEG_OVERRIDE_DS, llvm::X86Disassembler::SEG_OVERRIDE_ES, llvm::X86Disassembler::SEG_OVERRIDE_FS, llvm::X86Disassembler::SEG_OVERRIDE_GS, llvm::X86Disassembler::SEG_OVERRIDE_max } |
