WebPseudo-instructions. The RISCV specification also dictates several Pseudo Instructions. These aren't implemented in hardware, but are translated by the assembler to common tasks. WebPseudo-instructions are used in assembly source code like regular assembly instructions. Each pseudo-instruction is implemented at the machine level using an equivalent instruction. The movia pseudo-instruction is the only exception, being implemented with two instructions.

WebPseudo-Branches • The MIPS processor only supports two branch instructions, beq and bne, but to simplify your life the assembler provides the following other branches: blt $t0, $t1, Lab1 # Branch if $t0 < $t1 ble $t0, $t1, Lab2 # Branch if $t0 <= $t1 bgt $t0, $t1, Lab3 # Branch if $t0 > $t1 WebMar 14, 2024 · This is an alias for CSRRW x0, cycle, x0. Since cycle is a read-only CSR, then (whether this CSR exists or not) an attempt to write into it will generate an illegal instruction exception.

WebSince 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 complement) instruction does not exist. However, this is equivalent to sub a0, zero, a1.In other words, 0 - a1 is the same as -a1.
