This is a smoke test of dex conversion, which checks to see that uses
|
||||
of a known-null in contexts that require a specific type end up getting
|
||||
converted to the type in question. When executed, this sort of code
|
||||
will inevitably throw a NullPointerException, but if the opcode weren't
|
||||
correct, they would instead incorrectly fail verification.
|
||||
|
||||
If you inspect the expected output of this test, you will see that
|
||||
there are some surprising instructions in there, such as using
|
||||
aget-byte for what was a boolean[] in the source code. In these cases,
|
||||
the resulting output is still correct (passes verification and will
|
||||
throw a NullPointerException if ever executed). However, it happens
|
||||
that during translation there simply wasn't enough information to
|
||||
recover the "true" original meaning at the level of actual opcode
|
||||
selection.
|
||||
|
||||
This test compares emitted code against a known-good (via eyeballing)
|
||||
version, so it is possible for this test to spuriously fail if other
|
||||
aspects of conversion end up altering the output in innocuous ways.
