How to add a simple RISCV intrinsic in LLVM
I have a simple scalar instruction which I added to LLVM, which takes two inputs from GPR and writes the output also to GPR. I can compile C code using inline assembly for the new instruction. I would like to add it as an intrinsic.
JAL- RICSV Architecture
Why immediate[0] is set to zero for jump and link instruction in riscv architecture? What is the main purpose do do that?
format of RISCV instruction encoding in Spike?
In QEMU RISCV instruction sub encoded according to RISCV spec,
where dots represent variable bits, which encode 2 source and 1 destination register indices.
What’s the difference between the addi and li instructions in RISC-V? Which one is more efficient?
I have a simple question regarding the difference between the instruction addi
and li

calculate and print N! with RISC-V
given some number N in one of my registers i want to print it and print the value of N!
If an interrupt signal lasts for multiple cycles, will it be processed multiple times in RISC-V?
I am implementing a RISC-V CPU with privilege levels, but I encountered an issue regarding interrupt handling. As a beginner in computer architecture, I would like to ask:
