Will need to create a repro and file an upstream issue for this, but just FYI @androm3da in case this happens to ring a bell.

[androm3da]

Looks like a true crash and not an assertion?

Does not seem familiar to me. Are you building llvm/bootstrapping? EDIT: oh whoops didn't notice the repo.

Lmk if you want me to triage this case - happy to take care of it.

[androm3da]

Yeah it occurs to me now that there were some blockers when trying to bootstrap llvm+clang / canadian and I've probably not opened bugs against all of them.

[alexrp]

With assertions enabled, I see:

zig: /home/alexrp/Source/ziglang/zig-bootstrap/llvm/lib/CodeGen/ModuloSchedule.cpp:647: void llvm::ModuloScheduleExpander::generatePhis(llvm::MachineBasicBlock*, llvm::MachineBasicBlock*, llvm::MachineBasicBlock*, llvm::MachineBasicBlock*, ValueMapTy*, ValueMapTy*, InstrMapTy&, unsigned int, unsigned int, bool): Assertion `StageScheduled != -1 && "Expecting scheduled instruction."' failed.

Forgot to build with debug info however... will post a stack trace shortly.
