Set -Cpanic=abort in windows-msvc stack protector tests #148849

saethlin · 2025-11-11T23:55:37Z

I ran into a test failure with the 32-bit windows test on #117192, one of the tests has been incorrectly passing (until my change!) because it is picking up the stack protector from another function. I've tried to prevent that happening again by adding CHECK-DAGs for the start and end of each function.

I've also done my best to correct the comments, some were based on the fact that we used to run these tests with unwinding panics, but LLVM doesn't add protectors to function with SEH funclets so it's must more straightforward for these tests to use -Cpanic=abort.
