> You need to get the IR reproducer first using `clang -emit-llvm -S -mllvm -opt-bisect-limit=<n>`. It should be reproduced successfully with `opt -passes=instcombine`. Then you should use `llvm-reduce` to minimize the reproducer. Note that the InstCombine pass should be disabled during reduction via `--ir-passes=`.
