The intrinsics-atomics test fails with the following assertion: void llvm::Instruction::setInstructionSubclassData(unsigned short): Assertion(D & HasMetadataBit) == 0 && "Out of range value put into field"' failed.`. The relevant bit of the stack trace is this:
#4 0x00007ffff4b19c70 in setInstructionSubclassData (D=<optimized out>, this=<optimized out>) at /home/james/projects/rust/compiler/src/llvm/include/llvm/IR/Instruction.h:437
#5 getSubclassDataFromInstruction (this=<optimized out>, D=<optimized out>, this=<optimized out>) at /home/james/projects/rust/compiler/src/llvm/include/llvm/IR/Instructions.h:246
#6 setOrdering (this=<optimized out>, Ordering=<optimized out>) at /home/james/projects/rust/compiler/src/llvm/include/llvm/IR/Instructions.h:197
#7 setAtomic (this=<optimized out>, SynchScope=(llvm::CrossThread | unknown: 457338112), Ordering=<optimized out>) at /home/james/projects/rust/compiler/src/llvm/include/llvm/IR/Instructions.h:216
#8 LLVMBuildAtomicLoad (B=<optimized out>, source=<optimized out>, Name=<optimized out>, order=<optimized out>) at /home/james/projects/rust/compiler/src/rustllvm/RustWrapper.cpp:558
I made a small change to output what AtomicLoad was being given as an ordering: 0xf30eb7a0 though it changes every time.
