| # Testing the AutoDiffCodegen system is more complicated, because function- and | |
| # constructor calls have side-effects. In C++ the evaluation order and | |
| # the elision of copies is implementation defined. Between different compilers, | |
| # some expression might be evaluated in a different order or some copies might be | |
| # removed. | |
| # | |
| # Therefore, we run tests that expect a particular compiler behaviour only on gcc. | |
| # | |
| # The semantic tests, which check the correctness by executing the generated code | |
| # are still run on all platforms. | |

| # From the man page: | |
| # The C++ standard allows an implementation to omit creating a | |
| # temporary which is only used to initialize another object of the | |
| # same type. Specifying -fno-elide-constructors disables that | |
| # optimization, and forces G++ to call the copy constructor in all cases. | |
| # We use this flag to get the same results between different versions of | |
| # gcc and different optimization levels. Without this flag, testing would | |
| # be very painfull and might break when a new compiler version is released. | |
