And when I debuged, I found that it got an error at this line https://github.com/apache/tvm/blob/6c6ad6c43ad3cb378866683ed322316b173267aa/src/target/llvm/codegen_llvm.cc#L724

Environment

Operating System: Ubuntu1804 TVM version: Latet LLVM: llvm-17

Steps to reproduce

import tvm
import tvm.testing
from tvm import te
import numpy as np

tgt = tvm.target.Target(target="llvm")

n = te.var("n")
A = te.placeholder((n,), name="A")
B = te.placeholder((n,), name="B")

C = te.compute(A.shape, lambda i: A[i] + B[i], name="C")
s = te.create_schedule(C.op)

fadd = tvm.build(s, [A, B, C], tgt, name="myadd")

I tried reproducing this error and couldn't do so. I don't see anything obviously wrong with the TVM code, so my guess is that you're probably running into some LLVM bug.

Could you perhaps mention the exact LLVM commit in which you're seeing this error. For context, I used the latest LLVM main commit as of today and I don't see the issue with that commit

@qzylalala I have a similar problem with you. How did you solve it in the end?
