[cfe-dev] Where are CBlocks translated into code?

[Richard Catlin]

I want to understand how CBlocks are translated into code?  Does this happen at the C source code level? in the LLVM IR? or at runtime?  Where can I see the algorithms that implement CBlocks?

I would imagine that the code in the CBlock is wrapped in some function that pulls in the enclosing scopes variables that are used. 

Any help is appreciated.

Thanks.
