Just a minor clarification here - the above statement is true for 
x86_64 and aarch64; clang uses SEH on those architectures in both MSVC 
and mingw mode.

For i386, clang does use the MSVC exception handling mechanism in MSVC 
mode, but in mingw mode, it uses dwarf instead (and can use sjlj as an 
alternative).

For arm32, it doesn't support SEH generation at all. (In MSVC mode, it 
just refuses to generate unwind information, and in mingw mode, it 
defaults to dwarf).
