* Changed the type check for eval values to raise a TypeError for unsupported types, specifically excluding instances of tvm.tir.Buffer. This improves error handling and clarity in the Builder class.

* [Enhancement] Improve iterator handling in layout utilities and parallel operations

* Added a new function, DivideUnusedIterators, to detect per-iterator gaps in fused index expressions, enhancing the accuracy of unused iterator detection.
* Updated CompleteBufferFragment to prefer direct inversion for bijective index mappings and introduced a fallback mechanism for non-bijective cases, improving layout inversion robustness.
* Added a new test for layout inference in fused kernels to ensure correct compilation and execution without layout inversion failures.

* lint fix

* [Feature] Add support for SM70 tensor core MMA instructions

- Introduced new intrinsic `ptx_mma_sm70` for Volta GPUs, enabling m16n16k4 shape with FP16 inputs and FP16/FP32 accumulation.
- Added `GemmMMASm70` class for handling GEMM operations specific to SM70 architecture.
- Implemented layout functions for Volta swizzled layouts and updated existing GEMM layout inference logic.
- Updated `requirements-dev.txt` to include `apache-tvm-ffi` dependency.
- Added correctness evaluation script for testing GEMM operations on SM70.

* [Refactor] Update formatting and installation commands in scripts

- Modified `format.sh` to install `pre-commit` and `clang-tidy` with the `--user` flag for user-specific installations.
- Improved readability in `correctness_evaluation_sm70.py` by adjusting the formatting of pytest parameters.
- Cleaned up spacing and formatting in various C++ source files for better consistency and readability.
- Removed unnecessary comments and improved layout function definitions in `mma_sm70_layout.py` and `mma_sm70_macro_generator.py` for clarity.
- Ensured consistent formatting in layout initialization and swizzle functions.

* typo fix

* Update dependency version for apache-tvm-ffi in pyproject.toml to fix CI

* [Math] Add `tl.infinity` operation and update Python interface for infinity handling

- Implemented `infinity_op` in C++ to return infinity values for supported data types.
- Registered new operation `tl.infinity` with appropriate attributes.
- Updated Python interface to call the new `tl.infinity` operation instead of the previous method.

* Add unit tests for `tl.infinity` operation in TileLang

- Introduced a new test file `test_tilelang_language_infinity.py` to validate the behavior of the `tl.infinity` operation across multiple data types (float16, bfloat16, float32, float64).
- Implemented a kernel to fill a tensor with infinity values and asserted the correctness of the output against PyTorch's `torch.inf`.

* [Feature] Enhance fill operation to support various buffer types

- Added support for `BufferLoad` in the `fill` function to handle different buffer types.
- Updated `Fill` class to process region descriptors and buffer regions, improving flexibility in buffer handling.
- Introduced checks for static bounds in region definitions to ensure safety during operations.
- Refactored loop induction variable handling in `FillNode` to accommodate sliced regions.

* Enhance TCGEN05 support by adding new intrinsic operations and descriptors. Introduced `ptx_tcgen05_mma_ts` for tensor-memory to shared-memory instructions and `tcgen05_mma_arrive` for signaling barrier completion. Updated existing descriptors and code generation logic to accommodate these changes, ensuring compatibility with new instruction sets. Refactored related allocation functions and improved handling of shared memory descriptors.

* lint fix

* Refactor buffer reference handling in CUDA code generation and update test execution in tilelang. Ensure default annotations for unrolling are set correctly in TIR IR module.
