/EH controls whether to run destructor cleanups when exceptions are thrown.

There are three modifiers:

  • s: Cleanup after "synchronous" exceptions, aka C++ exceptions.
  • a: Cleanup after "asynchronous" exceptions, aka structured exceptions. The 'a' modifier is unimplemented and fundamentally hard in LLVM IR.
  • c: Assume that extern "C" functions are implicitly nounwind. The default is /EHs-c-, meaning cleanups are disabled.
