in 'undef', which I believe makes the value unrecoverable even with
entry values. Can call sites like that be described by DWARF? If so, I
guess a combination of entry-value variable locations and salvaging
the call-site arguments would work.
The isel example in https://reviews.llvm.org/D87233 is good --
although dropping the variable location there is largely because of
SelectionDAGs own limitations rather than the generated code. We can't
describe arguments that aren't used because they're not copied to a
virtual register.
In general, I reckon entry values will be a key pa...

For example, if we have:
int local = param1 + param2 + 123;
I think it would be good if we would be able to to represent the four different
permutations of the values of the parameters being
