## Summary Lifts 10 host-toolchain / CLI / process / utility modules from `python/tvm/contrib/` to a new `python/tvm/support/` package, and deletes two dead contrib shims. `tvm.support` is the home for Python helpers that integrate TVM with external CLIs and host-side tools — compilers, archivers, subprocess pools, and build-info queries. These are load-bearing internal pieces that TVM's compile/link/run paths depend on. `tvm.contrib` is reserved for optional vendor SDK integrations and experimental features. The distinction is documented in the `tvm.support` package docstring. Moved (one commit each): - `tvm.contrib.cc` → `tvm.support.cc` - `tvm.contrib.nvcc` → `tvm.support.nvcc` - `tvm.contrib.rocm` → `tvm.support.rocm` - `tvm.contrib.ndk` → `tvm.support.ndk` - `tvm.contrib.xcode` → `tvm.support.xcode` - `tvm.contrib.clang` → `tvm.support.clang` - `tvm.contrib.emcc` → `tvm.support.emcc` - `tvm.contrib.popen_pool` → `tvm.support.popen_pool` - `tvm.contrib.utils` → `tvm.support.utils` - `tvm.contrib.tar` → `tvm.support.tar` Deleted: - `tvm.contrib.spirv` — single `optimize()` wrapping `spirv-opt`; zero importers. - `tvm.contrib.rpc` — self-deprecation shim with "removed in 0.5" banner; honoring it. Package conversion: - `python/tvm/support.py` → `python/tvm/support/__init__.py` with inclusion-rule docstring. - `libinfo()` extracted into `python/tvm/support/libinfo.py`. - `FrontendTestModule` dropped (audit confirmed zero callers outside its own definition). ## Compatibility Hard break — no `tvm.contrib.<mod>` re-export shims. All callers updated in this PR. C++-side FFI registry keys (`tvm.contrib.nvcc.*`, etc.) are unchanged — only the Python module path moves. Renaming the FFI keys is a separate follow-up.
