1 | // These "-c" test cases run the dimexpr-match framework (see the hfa) on the C array. |

5 | // These tests don't use collections/array.hfa (see the -cfa version for that). |
---|
6 | // But `forall( [N] ) ...` is a laguage feature that does not depend on the new-array library. |
---|
7 | // In CFA, such an `N` is a fine value expression, and can be used as the dimension of a "C" array. |

8 | // This file's cases include `N` expressions when the compiler is non-Classic CFA. |

9 | // They are omitted from consideration |
---|
10 | // - under gcc, for obvious reasons |
---|
11 | // - or under classic CFA, beacuase its bahaviour on this C/CFA hybrid was complex, and there is no value in modeling an expctation of it |
---|
12 | // - whereas these are not really "C compatibility" cases |
