SIL Inspector

I wrote a small utility SILInspector [1] (which wraps around the output of xcrun swiftc -emit-sil and friends) for my presentation at GotoCon Berlin yesterday [2]. It’s primarily a tool that’s useful for seeing what gets generated by each stage of the pipeline and (for example) showing how in-lining optimisations can lead to further optimisations resulting in functions being completely excluded in compiled output.

It might be of interest to those experimenting with the compiler and/optimisations, although as I said, there’s nothing that can’t be done from the command line.

The presentation I gave at QCon London 2016 where I talked about SIL Inspector has now been published on InfoQ:

InfoQ

Open Source Swift Under the Hood

Alex Blewitt talks about Swift, the open source language released in December 2015 and available on Linux as well as OSX and iOS. He looks at the open-source project, how applications and libraries can be built for both platforms, the differences...
