Code

This happens on bjorn3/rust@b18b50c. By performing the following steps:

1. Put the following in config.toml:

profile = "compiler"
changelog-seen = 2

[build]
compiler-docs = false

[rust]
codegen-backends = ["llvm", "cranelift"]
parallel-compiler = true

2. Build using ./x.py build compiler/rustc_codegen_cranelift.
3. Remove the parallel-compiler = true line.
4. Build again using ./x.py build compiler/rustc_codegen_cranelift.
