[Tool] Add official compile-only CLI - #3045
Conversation
TileLang has no first-class compile-only path for CPU-only CI. This adds the official entry so later CE work can emit inspectable kernel source without a GPU. Signed-off-by: Oliver Zhang <zhiyuanzhang0904@163.com>
`--target cuda` should emit real CUDA C when the wheel has codegen FFI, and soft-fail clearly on Metal-style wheels instead of an AttributeError. Signed-off-by: Oliver Zhang <zhiyuanzhang0904@163.com>

When a caller uses a normal TVM target string with options, such as --target 'cuda -arch=sm_90', on a wheel without CUDA FFI, resolve_target preserves the string but this exact-equality check classifies it as non-CUDA. Lowering then enters the CUDA pipeline and leaks the underlying missing-FFI error instead of the advertised clear soft failure; determine the target kind after parsing the string rather than matching only bare cuda.
Useful? React with 👍 / 👎.
discover_prim_func skipped an earlier PrimFunc when a later @jit existed, and option-bearing CUDA strings skipped the FFI soft-fail. Signed-off-by: Oliver Zhang <zhiyuanzhang0904@163.com> Co-authored-by: Cursor <cursoragent@cursor.com>
