[Kobzol]

The checksum is unrelated, that's from the Python bootstrap test suite. Does src/llvm-project/compiler-rt exist on disk?

[hkBst]

No, there is nothing in src/llvm-project/

[Kobzol]

You need to checkout the submodule then. We should probably change bootstrap to error out if it's missing.

[saethlin]

Please do not do that. The LLVM submodule takes up a significant amount of disk space and is completely unnecessary for the majority of contributors.
