Fields

imm64: OperandKind

A 64-bit immediate integer operand.

This type of immediate integer can interact with SSA values with any IntType type.

uimm8: OperandKind

An unsigned 8-bit immediate integer operand.

This small operand is used to indicate lane indexes in SIMD vectors and immediate bit counts on shift instructions.

uimm128: OperandKind

An unsigned 128-bit immediate integer operand.

This operand is used to pass entire 128-bit vectors as immediates to instructions like const.

pool_constant: OperandKind

A constant stored in the constant pool.

This operand is used to pass constants to instructions like vconst while storing the actual bytes in the constant pool.

offset32: OperandKind

A 32-bit immediate signed offset.

This is used to represent an immediate address offset in load/store instructions.

ieee32: OperandKind

A 32-bit immediate floating point operand.

IEEE 754-2008 binary32 interchange format.

ieee64: OperandKind

A 64-bit immediate floating point operand.

IEEE 754-2008 binary64 interchange format.

intcc: OperandKind

A condition code for comparing integer values.

This enumerated operand kind is used for the icmp instruction and corresponds to the condcodes::IntCC` Rust type.

floatcc: OperandKind

A condition code for comparing floating point values.

This enumerated operand kind is used for the fcmp instruction and corresponds to the condcodes::FloatCC Rust type.

memflags: OperandKind

Flags for memory operations like load and store.

trapcode: OperandKind

A trap code indicating the reason for trapping.

The Rust enum type also has a User(u16) variant for user-provided trap codes.

atomic_rmw_op: OperandKind

A code indicating the arithmetic operation to perform in an atomic_rmw memory access.
