Comment at: lldb/packages/Python/lldbsuite/test_event/build_exception.py:8
         self.build_error = called_process_error.lldb_extensions.get(
-            "stderr_content", "<error output unavailable>")
+            "stderr_content", "<error output unavailable>").decode("utf-8") + 
called_process_error.lldb_extensions.get("stdout_content","<stdout output 
unavailable>").decode("utf-8")
 
----------------
This `.decode` call will be incorrect on python3 if `lldb_extensions` ever does 
not contain the `stderr_content` field. (That's because `"<error output 
unavailable>"`, a string object, does not have a `decode` method -- only 
`bytes` objects can be decoded in python3.

By the looks of things, stderr_content will always be filled in, so you should 
be able to just replace this with direct member access 
(`called_process_error.lldb_extensions.stderr_content.decode(...)`).

Also, if I'm not mistaken, this will just concatenate stdout and stderr without 
any sort of delimiters, or caring about the order in which they are produced. 
That could end up being confusing because the compilers stderr will come before 
the compiler command which wrote it. If we're not going to be merging the two 
streams in the proper sequence (I described one way in 
<https://reviews.llvm.org/D81697#2138665>), then it would be better to prefix 
each stream with it's own header (like you've done in 
<https://reviews.llvm.org/file/data/wxosaassniqt7keadc2v/PHID-FILE-6o2ea7gsgnrznam5k4ua/image.png>),
 so that it is clear that one is looking at two independent streams.

I believe this file is pretty much unused now. I've created D83545 to remove it.
