By enabling -Wunreachable-code-aggressive on Clang the following code paths are unreachable.
That code exists as commentary and, especially for sdvo, library functions that we may need in future.
I would argue that this code could be removed since it is in git history. It can be restored when needed.
This will make the code cleaner.
The ivb-gt1 case => as we now set the gt level for ivb, should we not enable the optimisation for ivb unaffected by the w/a? Just no one has taken the time to see if it causes a regression.
I don't know. I just found out that the code is unreachable.
For error state, the question remains whether we should revert to uncompressed data if the compressed stream is larger than the original.
I don't know too.
In this last two cases the code could be commented and the decisions and problems explained in the comment section.
