asmjit::x86::InstDB::InstSignature Struct Reference [¶]

Mode x86::InstDB::InstSignature::mode() constnodiscardnoexcept[¶]
Returns instruction operation mode.
bool x86::InstDB::InstSignature::supports_mode(Mode mode) constnodiscardnoexcept[¶]
Tests whether the instruction supports the given operating mode.
uint32_t x86::InstDB::InstSignature::op_count() constnodiscardnoexcept[¶]
Returns the number of operands of this signature.
uint32_t x86::InstDB::InstSignature::implicit_op_count() constnodiscardnoexcept[¶]
Returns the number of implicit operands this signature has.
bool x86::InstDB::InstSignature::has_implicit_operands() constnodiscardnoexcept[¶]
Tests whether this instruction signature has at least one implicit operand.
const uint8_t* x86::InstDB::InstSignature::op_signature_indexes() constnodiscardnoexcept[¶]
Returns indexes to _op_signature_table for each operand of the instruction.
Note
The returned array always provides indexes for all operands (see Globals::kMaxOpCount) even if the instruction provides less operands. Undefined operands have always index of zero.
uint8_t x86::InstDB::InstSignature::op_signature_index(size_t index) constnodiscardnoexcept[¶]
Returns index to _op_signature_table, corresponding to the requested operand index of the instruction.
const OpSignature& x86::InstDB::InstSignature::op_signature(size_t index) constnodiscardnoexcept[¶]
Returns OpSignature corresponding to the requested operand index of the instruction.
uint8_t x86::InstDB::InstSignature::_op_count[¶]
Count of operands in op_index (0..6).
uint8_t x86::InstDB::InstSignature::_mode[¶]
Architecture modes supported (X86 / X64).
uint8_t x86::InstDB::InstSignature::_implicit_op_count[¶]
Number of implicit operands.
uint8_t x86::InstDB::InstSignature::_reserved[¶]
Reserved for future use.
uint8_t x86::InstDB::InstSignature::_op_signature_indexes[Globals::kMaxOpCount][¶]
Indexes to OpSignature table.
