| # pieces of each test are compiled with different compilers. The |

| # ALT_CC_UNDER_TEST in the environment. |

| # struct-layout-1 are generated structure layout interoperability tests, |
| # so a generator first needs to be compiled on host, run there and the |
| # generated tests then compiled on build and executed on target. |
