Portable MLIR Toolchain

This repository provides pre-built MLIR binaries. Standalone zstd executables are also provided as separate assets for each supported platform to facilitate decompression.

Installation

For installation instructions, please refer to the setup-mlir repository. The repository provides

• an action for setting up MLIR in GitHub Actions and
• installation scripts for setting up MLIR locally.

Build Scripts

If desired, you can run the staged build scripts directly. Refer to

• scripts/toolchain/linux/build-zstd.sh, scripts/toolchain/linux/build-mold.sh, and scripts/toolchain/linux/build-mlir.sh for Linux,
• scripts/toolchain/macos/build-zstd.sh and scripts/toolchain/macos/build-mlir.sh for macOS, and
• scripts/toolchain/windows/build-zstd.ps1, scripts/toolchain/windows/build-lld.ps1, and scripts/toolchain/windows/build-mlir.ps1 for Windows.

The usage is documented in each script. Linux builds run in a manylinux container and therefore require Docker on the host system.

Windows Debug Release Assets

Windows Debug MLIR archives may be published as split assets named llvm-mlir_<version>_<target>_debug.tar.zst.part-000, .part-001, ... to stay below GitHub's per-asset size limit. Reassemble the parts (in order) before extracting the archive.

PowerShell:

$parts = Get-ChildItem -File "llvm-mlir_*_debug.tar.zst.part-*" | Sort-Object Name
$out = "llvm-mlir_debug.tar.zst"
if (Test-Path $out) { Remove-Item $out -Force }
$target = [System.IO.File]::Open($out, [System.IO.FileMode]::CreateNew)
try {
  foreach ($p in $parts) {
    $in = [System.IO.File]::OpenRead($p.FullName)
    try { $in.CopyTo($target) } finally { $in.Dispose() }
  }
} finally {
  $target.Dispose()
}

Bash:

cat llvm-mlir_*_debug.tar.zst.part-* > llvm-mlir_debug.tar.zst
