.. py:module:: ida_ua
.. autoapi-nested-parse::
Functions that deal with the disassembling of program instructions.
There are 2 kinds of functions:
* functions that are called from the kernel to disassemble an instruction.
These functions call IDP module for it.
* functions that are called from IDP module to disassemble an instruction.
We will call them 'helper functions'.
Disassembly of an instruction is made in three steps:
0. analysis: ana.cpp
1. emulation: emu.cpp
2. conversion to text: out.cpp
The kernel calls the IDP module to perform these steps. At first, the kernel
always calls the analysis. The analyzer must decode the instruction and fill
the insn_t instance that it receives through its callback. It must not change
anything in the database.
The second step, the emulation, is called for each instruction. This step must
make necessary changes to the database, plan analysis of subsequent instructions,
track register values, memory contents, etc. Please keep in mind that the kernel
may call the emulation step for any address in the program - there is no ordering
of addresses. Usually, the emulation is called for consecutive addresses but
this is not guaranteed.
The last step, conversion to text, is called each time an instruction is
displayed on the screen. The kernel will always call the analysis step before
calling the text conversion step. The emulation and the text conversion steps
should use the information stored in the insn_t instance they receive. They
should not access the bytes of the instruction and decode it again - this
should only be done in the analysis step.
.. tip::
The `IDA Domain API <https://ida-domain.docs.hex-rays.com/>`_ simplifies
common tasks and provides better type hints, while remaining fully compatible
with IDAPython for advanced use cases.
For instruction operations, see :mod:`ida_domain.instructions`.

Module Contents
---------------
.. py:class:: operands_array(data: op_t (&)[8])
Bases: :py:obj:`object`
.. py:attribute:: thisown
.. py:attribute:: data
:type: op_t (&)[8]
.. py:attribute:: bytes
.. py:class:: op_t
Bases: :py:obj:`object`
.. py:attribute:: thisown
.. py:attribute:: n
:type: uchar
Number of operand (0,1,2). Initialized once at the start of work. You have no right to change its value.
.. py:attribute:: type
:type: optype_t
Type of operand (see Operand types)
.. py:attribute:: offb
:type: char
Offset of operand value from the instruction start (0 means unknown). Of course this field is meaningful only for certain types of operands. Leave it equal to zero if the operand has no offset. This offset should point to the 'interesting' part of operand. For example, it may point to the address of a function in `call func ` or it may point to bytes holding '5' in `mov ax, [bx+5] ` Usually bytes pointed to this offset are relocated (have fixup information).
.. py:attribute:: offo
:type: char
Same as offb (some operands have 2 numeric values used to form an operand). This field is used for the second part of operand if it exists. Currently this field is used only for outer offsets of Motorola processors. Leave it equal to zero if the operand has no offset.
.. py:attribute:: flags
:type: uchar
Operand flags
.. py:method:: set_shown() -> None
Set operand to be shown.
.. py:method:: clr_shown() -> None
Set operand to hidden.
.. py:method:: shown() -> bool
Is operand set to be shown?
.. py:attribute:: dtype
:type: op_dtype_t
Type of operand value (see Operand value types). This is the type of the operand itself, not the size of the addressing mode. for example, byte ptr [epb+32_bit_offset] will have the dt_byte type.
.. py:attribute:: reg
:type: uint16
number of register (o_reg)
.. py:attribute:: phrase
:type: uint16
number of register phrase (o_phrase,o_displ). you yourself define numbers of phrases as you like
.. py:method:: is_reg(r: int) -> bool
Is register operand?
.. py:attribute:: value
:type: int
operand value (o_imm) or outer displacement (o_displ+OF_OUTER_DISP). integer values should be in IDA's (little-endian) order. when using ieee_realcvt(), floating point values should be in the processor's native byte order. dt_double and dt_qword values take up 8 bytes (value and addr fields for 32-bit modules). NB: in case a dt_dword/dt_qword immediate is forced to float by user, the kernel converts it to processor's native order before calling FP conversion routines.
.. py:method:: is_imm(v: int) -> bool
Is immediate operand?
.. py:attribute:: addr
:type: ida_idaapi.ea_t
virtual address pointed or used by the operand. (o_mem,o_displ,o_far,o_near)
.. py:attribute:: specval
:type: ida_idaapi.ea_t
This field may be used as you want.
.. py:attribute:: specflag1
:type: char
.. py:attribute:: specflag2
:type: char
.. py:attribute:: specflag3
:type: char
.. py:attribute:: specflag4
:type: char
.. py:method:: assign(other: op_t) -> None
.. py:method:: has_reg(r)
Checks if the operand accesses the given processor register
.. py:attribute:: value64
.. py:data:: cvar
.. py:data:: o_void
No Operand.
.. py:data:: o_reg
General Register (al,ax,es,ds...).
The register number should be stored in op_t::reg. All processor registers, including special registers, can be represented by this operand type.
.. py:data:: o_mem
A direct memory reference to a data item. Use this operand type when the address can be calculated statically.
A direct memory data reference whose target address is known at compilation time. The target virtual address is stored in op_t::addr and the full address is calculated as to_ea( insn_t::cs, op_t::addr ). For the processors with complex memory organization the final address can be calculated using other segment registers. For flat memories, op_t::addr is the final address and insn_t::cs is usually equal to zero. In any case, the address within the segment should be stored in op_t::addr.
.. py:data:: o_phrase
An indirect memory reference that uses a register: [reg] There can be several registers but no displacement.
A memory reference using register contents. Indexed, register based, and other addressing modes can be represented with the operand type. This addressing mode cannot contain immediate values (use o_displ instead). The phrase number should be stored in op_t::phrase. To denote the pre-increment and similar features please use additional operand fields like op_t::specflag... Usually op_t::phrase contains the register number and additional information is stored in op_t::specflags... Please note that this operand type cannot contain immediate values (except the scaling coefficients).
.. py:data:: o_displ
An indirect memory reference that uses a register and has an immediate constant added to it: [reg+N] There can be several registers.
A memory reference using register contents with displacement. The displacement should be stored in the op_t::addr field. The rest of information is stored the same way as in o_phrase.
.. py:data:: o_imm
An immediate Value (constant).
Any operand consisting of only a number is represented by this operand type. The value should be stored in op_t::value. You may sign extend short (1-2 byte) values. In any case don't forget to specify op_t::dtype (should be set for all operand types).
.. py:data:: o_far
An immediate far code reference (inter-segment)
If the current processor has a special addressing mode for inter-segment references, then this operand type should be used instead of o_near. If you want, you may use PR_CHK_XREF in processor_t::flag to disable inter-segment calls if o_near operand type is used. Currently only IBM PC uses this flag.
.. py:data:: o_near
An immediate near code reference (intra-segment)
A direct memory code reference whose target address is known at the compilation time. The target virtual address is stored in op_t::addr and the final address is always to_ea( insn_t::cs, op_t::addr). Usually this operand type is used for the branches and calls whose target address is known. If the current processor has 2 different types of references for inter-segment and intra-segment references, then this should be used only for intra-segment references.
If the above operand types do not cover all possible addressing modes, then use o_idpspec... operand types.

The first line printed with indent < 0 is considered as the most important line at the current address. Usually it is the line with the instruction itself. This line will be displayed in the cross-reference lists and other places. If you need to output an additional line before the main line then pass DEFAULT_INDENT instead of -1. The kernel will know that your line is not the most important one.

:type: size_t
.. py:method:: construct_macro(insn: insn_t, enable: bool) -> bool
Construct a macro instruction. This function may be called from ana() to generate a macro instruction.
The real work is done by the 'build_macro()' virtual function. It must be defined by the processor module.
construct_macro() modifies the database using the info provided by build_macro(). It verifies if the instruction can really be created (for example, that other items do not hinder), may plan to reanalyze the macro, etc. If the macro instructions are disabled by the user, construct_macro() will destroy the macro instruction. Note: if INSN_MODMAC is not set in insn.flags, the database will not be modified.
:param insn: the instruction to modify into a macro
:param enable: enable macro generation
:returns: true: the macro instruction is generated in 'insn'
:returns: false: did not create a macro
.. py:method:: build_macro(insn: insn_t, may_go_forward: bool) -> bool
Try to extend the instruction.
This function may modify 'insn' and return false; these changes will be accepted by the kernel but the instruction will not be considered as a macro.
:param insn: Instruction to modify, usually the first instruction of the macro
:param may_go_forward: Is it ok to consider the next instruction for the macro? This argument may be false, for example, if there is a cross reference to the end of INSN. In this case creating a macro is not desired. However, it may still be useful to perform minor tweaks to the instruction using the information about the surrounding instructions.
:returns: true if created an macro instruction.
.. py:function:: decode_preceding_insn(out: insn_t, ea: ida_idaapi.ea_t) -> Tuple[ida_idaapi.ea_t, bool]
