Rv32

rv32

RISC-V 32-bit (RV32) dialect operations and types.

This module defines the RV32-specific variant of RISC-V operations, using 5-bit immediates for 32-bit architectures.

RV32 = Dialect('rv32', [LiOp, GetRegisterOp], []) module-attribute

LiOp

Bases: RISCVCustomFormatOperation, RISCVInstruction, HasFolderInterface, ABC

Loads a 32-bit immediate into rd.

This is an assembler pseudo-instruction.

See external documentation.
