Re: [PATCH 00/16] Unit tests framework (v3)

[Bernd Schmidt]

So Jeff and I just had a chat, and we came up with some thoughts about 
how to proceed. I think we both agree that it would be good to have a 
special testing backend, along with frontends designed to be able to 
read in gimple or rtl that can be operated on. That's more of a 
long-term thing.

For some of the simpler infrastructure tests such as the ones in this 
patch kit (bitmap, vec or wide-int functionality testing and such), we 
had the idea of putting these into every ENABLE_CHECKING compiler, and 
run them after building stage1, controlled by a -fself-test flag. It's 
better to detect such basic failures early rather than complete a full 
bootstrap and test cycle. It also keeps the tests alongside the rest of 
the implementation, which I consider desirable for such relatively 
simple data structures.

Thoughts?
