[LLVMdev] Nested exception handlers
...#39;ve got exceptions working, I'm kind of wondering how to
handle the case of nested "try" blocks. Say I have some code that looks
like this:
try {
try {
if (test) {
// throw something
} else {
return;
}
} catch e:Except1 {
} catch e:Except2 {
} finally {
}
// more code...
} catch e:Except3 {
} finally {
}
Turning this into a list of basic blocks is starting to get rather
complex. In particular:
* For the innermost try block, there will be 4 possible selectors,
corresponding to Except1, Except2, Except3...
