| # This test demonstrates "layered" multilib in which more than one |
| # multilib is matched. |
| # For example a multilib containing only a no-exceptions libc++ could |
| # be layered on top of a multilib containing C libs. This avoids the |
| # need to duplicate the C library for every libc++ variant. |
| # However -fno-exceptions is not yet supported for multilib selection |
| # so we use a more contrived -mfloat-abi example instead. |
