Wouldn't you still need to restore the stack before leaving the function (tail
call in this case)?
Yes.
dmd rewrites try-catch-finally into try-{try-catch}-finally, which makes it
easier to generate code, because fewer special cases and fewer bugs. I've
become a big fan of that technique
Except that we actually need to flatten all the nesting into a single landing
pad anyway.
I don't know why that would be true. gdc generates multiple landing pads.
How would you do this in DMD? I didn't realize you could even have
multiple EH table entries attached to a single code location.
You can't. The most deeply nested one gets the table entry.
