| # This file is in two parts: |
| # 1. A list of library variants. |
| # 2. A mapping from flags generated from command line arguments to further |
| # flags. |
| |
| # How does clang use this file? |
| # 1. If the ToolChain class for the architecture supports this form of |
| # multilib it then it loads the file if present in sysroot. |
| # 2. Generate flags from the user provided arguments. |
| # (Use `clang -print-multi-flags-experimental` to see which flags are |
| # generated). |
| # 3. Compare the arguments against each regular expression and store |
| # associated flags if there's a match. |
| # 4. Find the last library variant whose flags are a subset of the |
| # flags derived from the user provided arguments. |
| # 5. Use the directory for the library variant as the sysroot. |
| |
| # Clang will emit an error if this number is greater than its current multilib |
| # version or if its major version differs, but will accept lesser minor |
| # versions. |
| MultilibVersion: 1.0 |
| |
| # The first section of the file is the list of library variants. |
| # A library is considered compatible if the are a subset of the flags derived |
| # from the arguments provided by the user. |
| # If multiple libraries are deemed compatible then the one that appears |
| # last in the list wins. A ToolChain may instead opt to use more than one |
| # multilib, layered on top of each other. |
