Swift TOT is currently taking a very long time (and upwards of 8GB) to build SwiftPM. I filed:
https://bugs.swift.org/browse/SR-2754
can someone on the compiler take a look? This makes it hard to develop with TOT.
- Daniel
Does this look related to the type checker (I saw Mark’s comments in the SR) or something else?

I'm assuming its the type checker based on how it manifests (and we haven't changed anything interesting in the module that is slow to build), but I haven't looked at any samples.

I just pulled this up under Instruments and found that 94% of the compile time for StringMangling.swift.o, which seems to be where all the time goes, is spent in performLLVM, so this doesn’t look like a type checker issue.
Weight Self Weight Symbol Name
10.32 min 94.4% 1.00 ms performLLVM(swift::IRGenOptions&, swift::DiagnosticEngine&, llvm::sys::SmartMutex<false>*, llvm::GlobalVariable*, llvm::Module*, llvm::TargetMachine*, swift::version::Version const&, llvm::StringRef)
I attached a screen shot from Instruments to the bug.

Thanks! I guess this showed up as a result of the most recent LLVM sync then?

Yes, that seems like the most likely explanation.
