- Add F128 support to TypeTree Kind enum - Implement TypeTree FFI bindings and conversion functions - Add typetree.rs module for metadata attachment to LLVM functions - Integrate TypeTree generation with autodiff intrinsic pipeline - Support scalar types: f32, f64, integers, f16, f128 - Attach enzyme_type attributes as LLVM string metadata for Enzyme Signed-off-by: Karan Janthe <[email protected]>
- Fix nott-flag test to emit LLVM IR and check enzyme_type attributes - Replace TODO comments with actual TypeTree metadata verification - Test that NoTT flag properly disables TypeTree generation - Test that TypeTree enabled generates proper enzyme_type attributes Signed-off-by: Karan Janthe <[email protected]>
- Add specific tests for f32, f64, i32, f16, f128 TypeTree generation - Verify correct enzyme_type metadata for each scalar type - Ensure TypeTree metadata matches expected Enzyme format Signed-off-by: Karan Janthe <[email protected]>
