   1 // Ensure that operator new/delete are still replaceable using static-libsan.

   3 // FIXME: Weak symbols aren't supported on Windows, although some code in
   4 // compiler-rt already exists to solve this problem. We should probably define
   5 // the new/delete interceptors as "weak" using those workarounds as well.
   6 // UNSUPPORTED: target={{.*windows.*}}

   8 // darwin only supports `shared-libsan`.
