When doing more investigations related to this PR: https://github.com/bytecodealliance/wasm-micro-runtime/pull/2619 We found that in some scenarios the constant might not be directly available to the LLVM IR builder, e.g.: ``` (func $const_ret (result i32) i32.const -5 ) (func $foo (i32.shr_u (i32.const -1) (call $const_ret)) (i32.const 31) ) ``` In that case, the right parameter to `i32.shr_u` is not constant, therefore the `SHIFT_COUNT_MASK` isn't applied. However, when the optimization is enabled (`--opt-level` is 2 or 3), the optimization passes resolve the call into constant, and that constant is poisoned, causing the compiler to resolve the whole function to an exception. |
