$ cat main.go
package main

import (
    "math"
)

func main() {
    var x = 1
    _ = x<<(math.MaxUint<<0)
}

Expected:

Get accepted and evaluated as 0, as seen in for example:

package main

import (
    "math"
)

func f(x int) {
}

func main() {
    var x = 1
    f(x<<(math.MaxUint))
}

Which ends up getting turned into the following intermediate llvm code:

[...]
define void @project.main() {
_llgo_0:
  call void @project.f(i64 0)
  ret void
}
