static |
Adds exception related arguments to the driver command arguments.
There's a master flag, -fexceptions and also language specific flags to enable/disable C++ and Objective-C exceptions. This makes it possible to for example disable C++ exceptions but enable Objective-C exceptions.

◆ parseClangCLEHFlags()
|
static |
/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.
