Halide's build of LLVM libraries and tools for development.
This package provides a Python wheel containing LLVM libraries and tools compiled specifically for Halide development. It includes essential LLVM components with a focused configuration optimized for Halide's needs.
- LLVM Core Libraries with assertions and RTTI enabled
- Clang compiler and tools
- LLD linker
- Clang Tools Extra for additional development utilities
The build supports the following target architectures:
- X86
- ARM
- NVPTX (CUDA)
- AArch64
- Hexagon
- PowerPC
- WebAssembly
- RISC-V
Due to the large size of LLVM binaries, this package is hosted on a custom PyPI index:
pip install halide-llvm --extra-index-url https://pypi.halide-lang.org/simple/This package uses scikit-build-core for building. The version is automatically
determined from the LLVM source being built.
- Python 3.12 or later
- CMake 4.0 or later
- C++ compiler
pip install -e .The LLVM build configuration can be customized by modifying the
halide-llvm_GIT_TAG variable to specify a different LLVM version:
"main"- Latest development version"llvmorg-X.Y.Z"- Specific release version (e.g., "llvmorg-18.1.0")
This build is specifically configured for Halide development with:
- Assertions enabled for debugging
- Exception handling support
- RTTI (Run-Time Type Information) enabled
- Zlib compression support
- Most optional tools and utilities disabled to reduce build time and size
