llvm.eh.return?

Can someone tell me what the C/C++ statement can generate llvm ir (intrinsic) @llvm.eh.return.i32 by clang? Or any statement of high level language can get @llvm.eh.return.i32.

This intrinsic is created via expansion of eh_return builtin. This
builtin is used by compiler runtime library to provide unwinding
functionality. You can look into libunwind / libgcc sources for an
example.
