| # Dataset Card for TheStack-IRIS |
|
|
| TheStack-IRIS is a training dataset for GIMPLE IR to LLVM IR translation, derived from [The Stack v1 (dedup)](https://huggingface.co/datasets/bigcode/the-stack-dedup). It contains ~310k C code samples paired with their corresponding GIMPLE and LLVM intermediate representations. |
|
|
| ## Dataset Structure |
|
|
| The dataset extends The Stack with additional IR fields: |
|
|
| - `content`: C source code |
| - `irs`: Dictionary containing intermediate representations: |
| - `gcc_gimple`: GIMPLE IR generated by GCC v15.2.0 |
| - `clang`: LLVM IR generated by Clang v22.0.0 |
| - `max_stars_repo_name`: Repository name for attribution |
| - `max_stars_repo_licenses`: Repository licenses |
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| # Load dataset |
| ds = load_dataset("HPAI-BSC/TheStack-IRIS", split="train") |
| |
| # Example: access a sample |
| sample = ds[0] |
| c_code = sample["content"] |
| gimple_ir = sample["irs"]["gcc_gimple"] |
| llvm_ir = sample["irs"]["clang"] |
| repo_name = sample["max_stars_repo_name"] |
| ``` |
|
|
| ## Dataset Creation |
|
|
| TheStack-IRIS is created by filtering [The Stack v1 (dedup)](https://huggingface.co/datasets/bigcode/the-stack-dedup) C samples and extending them with intermediate representations: |
|
|
| | Stage | # Samples | Description | |
| |-------|-----------|-------------| |
| | The Stack C samples | 8,625,559 | Original C code from The Stack | |
| | License filtering | 8,136,034 | Samples with permissive open-source licenses |
| | Compile successfully | 867,101 | Samples that compile with both GCC v15.2.0 and Clang v22.0.0 |
| | IR generation | 306,841 | Samples with GIMPLE and LLVM IR aligned pairs |
|
|
|
|
| ### Filtering Process |
|
|
| 1. Selected C language samples from [The Stack v1 (dedup)](https://huggingface.co/datasets/bigcode/the-stack-dedup) |
| 2. Compiled each sample with GCC v15.2.0 and Clang v22.0.0 at `-O0` |
| 3. Retained samples that compile successfully with both compilers |
| 4. Generated GIMPLE using `gcc -fdump-tree-gimple -O0` |
| 5. Generated LLVM IR using `clang -emit-llvm -O0` |
|
|
| The dataset preserves all original The Stack metadata for proper attribution. |
|
|
| ### License |
|
|
| The dataset inherits licenses from The Stack. We used a subset of the top-20 permissive licenses. Each sample includes repository license information in the max_stars_repo_licenses field for proper attribution. |
| |
| The licenses of this subset include: |
| |
