145: The prefix "PETSC_" is added to the argument.

160: To avoid prepending "PETSC_", say to add custom checks in user code, one can use e.g.

165: Getting something that works in C and CPP for an arg that may or may not be defined is tricky. Here, if we have

168: a (... 1, 0) pair, and when the last step cherry picks the 2nd arg, we get a zero.

1955: . PETSC_PREFETCH_HINT_T0 - Fetch to all levels of cache and evict to the closest level. Use this when the memory will be reused regularly despite necessary eviction from L1.

1957: - PETSC_PREFETCH_HINT_T2 - Fetch to high-level cache only. (On many systems, T0 and T1 are equivalent.)
