What does this declaration mean? Is decorator_traceback
decorator_traceback_17 = (system__traceback_entries__traceback_entry___XDLU_0__18446744073709551615[1 .. T.2] &) traceback_16;
According to this, decorator_traceback is a GIMPLE register. It seems
to be a pointer of some kind? I can't parse the original declaration.
You'll have to figure out why we first think that decorator_traceback is
a gimple reg, and then we think otherwise.
This may help. Put this test in add_may_alias:
if (is_gimple_reg (var) || is_gimple_reg (alias))
abort ();
