// Helper macro THRUST_JOIN (based on BOOST_JOIN): |
|
// The following piece of macro magic joins the two |
|
// arguments together, even when one of the arguments is |
|
// itself a macro (see 16.3.1 in C++ standard). The key |
|
// is that macro expansion of macro arguments does not |
|
// occur in THRUST_DO_JOIN2 but does in THRUST_DO_JOIN. |
|
