 1 | # The LLVM Compiler Infrastructure
 2 | 
 3 | This repository houses versions of LLVM that support downgrading IR to previous versions.
 4 | Specifically, LLVM 5.0 and LLVM 7.0, as required to target respectively Apple's Metal and
 5 | NVIDIA's NVVM.
 6 | 
 7 | The actual code does not live on the `main` branch, but in branches versioned after the
 8 | LLVM version they contain: `downgrade_release_13` to `downgrade_release_17`.
 9 | 
10 | We currently only aim to support the LLVM versions that are used by the Julia programming
11 | language. In addition, these branches may contain additional patches as used by Julia.
