# Please keep the LLVM dependency block separate. Since LLVM is slotted,
# we need to *really* make sure we're not pulling more than one slot
# simultaneously.
# How to use it:
# 1. List all the working slots (with min versions) in ||, newest first.
# 2. Update the := to specify *max* version, e.g. < 11.
# 3. Specify LLVM_MAX_SLOT, e.g. 10.
