It is a pseudo instruction. It is eqvivalent to jalr x0, x1, 0 . x1 holds the return address. Effectively jumping to the return address. A ret instruction may serve as a return if the function it ends was called with no fork (e.g. the second ret ending f after the call of f in main returns to RISCV is an open instruction set initially developed by Berkeley University, To get the RISCV assembler and simulator, follow instructions of the first Contribute to riscv-non-isa/riscv-asm-manual development by creating an account You can use an UNIMP pseudo-instruction, which should trap in nearly all The RISC-V project de/ines and describes a standardized Instruction Set RET. Example: RET. # Goto *x1, i.e., PC = x1. RISC-V Architecture Summary / Also, RISC-V does not have a dedicated instruction for return. The ret is a pseudo-instruction that is expanded to jalr zero, 0(ra) , which sets the programSince RISC-V is a reduced instruction set, many instructions that can be completed by using another instruction are left off. For example, the neg a0, a1 (two's Intro For information on assembler programming: RISC-V Assembly mie, %1" /* read and write atomically */ : "=r" (ret) /* output: register %0 */ : "r" In RISC-V world, what does JALR instruction do? What does ra register do? What does ret assembly do? ret : Return from subroutine. When executing an xRET instruction, supposing xPP holds the value y, xIE is set to xPIE; the privilege mode is changed to y; xPIE is set to 1; and xPP is set to Is there any difference between mret and ret instruction when risc-v core is operating in machine mode?
