Hi Talin, if you change @throwSomething so that it prints a message
if the _Unwind_RaiseException call returns, then you will see that
it does in fact return.
define internal fastcc void @throwSomething() {
entry:
%throwable = malloc %Throwable
call fastcc void @Throwable.construct(%Throwable* %throwable)

Well, after much labor, I think I have managed to create a personality
function that works. But I must say it is frightening how complicated
all of this stuff is.

[LLVMdev] Exception Personality Function
...n isSubclass() method. This can serve as an
example for how to use exceptions for languages that are different from C++.
To invoke the personality function and have it catch an exception, the
IR that you generate should look like the following:
try:
;; Throw some exception
invoke { } @"throwSomething"() to label %endTry unwind label %catch
catch:
;; Catch and decode the exception
%eh_ptr = call i8* @llvm.eh.exception()
%eh_action = call i32 (i8*, i8*, ...)* @llvm.eh.selector.i32(
i8* %eh_ptr,
i8* bitcast (i32 (i32, i32, i64, i8*, i8*)* @__tart_eh_personality
to i8*),...
