Invalid assumption of stack pointer in compiled .wasm. about life HOT 1 CLOSED

By using optimization level 3, we get a far more straightforward *.wat.

(module
 (type $FUNCSIG$vi (func (param i32)))
 (import "env" "logi" (func $logi (param i32)))
 (table 0 anyfunc)
 (memory $0 1)
 (data (i32.const 12) "\04\00\00\00")
 (export "memory" (memory $0))
 (export "main" (func $main))
 (func $main (; 1 ;) (result i32)
  (call $logi
   (i32.const 134)
  )
  (call $logi
   (i32.const 13)
  )
  (call $logi
   (i32.const 52)
  )
  (i32.const 0)
 )
)

If you are using the online compiler https://mbebenita.github.io/WasmExplorer/, note that binaries produced by that compiler (alongside others such as Emscripten) that assumes memory is pre-allocated, and that a stack pointer is specified at offset 4.

Would recommend directly compiling w/ LLVM and clang, or otherwise use an option that we've been testing with which is creating WebAssembly modules in Rust and thereafter compiling them down to *.wasm with cargo.

from life.
