Drive-by, I'm on vacation.
Glad someone fixes this, even if I was hoping we replace all this by invoking the Attributor only for the IR attributes we are looking for here.
================
Comment at: llvm/lib/Transforms/IPO/FunctionAttrs.cpp:702
+ // if a reloaded copy is written to, thus we must give up.
+ return Attribute::None;
+ // Push users for processing once we finish this one
----------------
I don't know if it is checked but unwinding is the same issue as writes. The Attributor code might have even more corner cases covered.
