Hi Dale,
> Arrange for only 1 of multiple branches to landing pad to be kept.
you seem to assume that there is at most one landing pad block for
a given MBB, i.e. that all invokes in the MBB unwind to the same
landing pad. Are you sure that's true?
Ciao,

Hi Dale,

it struck me that this patch seems to assume that if a successor
is a landing pad then it is necessarily a landing pad for the
current MBB. But couldn't it be the landing pad for some other
MBB, and simply a normal suc

Hey, you are the one who used getInt64 to get the array length! :)

Actually a testcase would be pointless, since the compiler crashes
during the (Ada) compiler build. It wouldn't be pointless if I
could make a C or C++ testcase, but I don't think it can be done
except in
