(#ifdef is not available in .s file) Ok, I guess I was incorrectly assuming the stack should be non-executable by default on all platforms. In this case, let's rewrite the test to have a variable that is actually in the .data section (therefore guaranteed to be non-executable), and pass a pass a pointer to it to `nonstandard_stub`. The core requirement is that the pointer passed to `nonstandard_stub` must simply point to some kind of non-executable memory. I can do this. ================ Comment at: lldb/test/Shell/Unwind/Inputs/thread-step-out-ret-addr-check.s:13 # memory check. +nonstandard_stub: _nonstandard_stub: ---------------- Maybe we can just remove the underscore version, and simply use `nonstandard_stub` if it will work everywhere?
