Actually there's a little bit of remorsing on our side. We've been experimenting with the CBackend and have been trying to build a product around it.
I guess I missed the thread which doomed the CBackend to SVN deletion.
Was it dropped due to a lack of maintainers?
What was the impact on other targets and the LLVM arch since this is more of a raising to HLL rather than a lowering to ASM?
Just curious, I'm cc'ing our internal stakeholders in the event they have any commentary.
