[PATCH] D138270: [clang][Sema] Skip checking int expressions for overflow in constexpr functions

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added a comment.

We may not have good code coverage, what about a case like this:

  constexpr void f() {
      int arr[10]{};
      arr[1024*1024*1024*1204];
  }

do you still obtain:

   error: constexpr function never produces a constant expression 
[-Winvalid-constexpr]
  constexpr void f() {
                 ^
