Compiler extensions

[edrickhong]

Can we have extension support to the compiler? I currently want the compiler to store some meta data to make pipeline creation simpler. I'd rather have some extension I can add to the compiler than have to muck about its guts.

Is it possible to have issue #701 evolve to include the information you want?

[edrickhong]

I don't see why not. My main motivation is to make pipeline creation simpler since a lot of the data is already in the shader. I do think some form of extension mechanism would be great though. I've always wanted to have the c compiler do more but support for extending it tends to be so poor it's not worth it.

@edrickhong does spirv-reflect address the need to gather metadata for pipeline creation?
