<div dir="ltr"><div style>Also, could there be a way (maybe in a future clang release) for me to get static type checking for my own types, such as __float128 or pair types like {long,long} (which are not in the MPI standard)? It can't truly be a static value because I have to create the type at run-time, but perhaps there could be a way to tell clang "I promise to set this type up like so."</div>

Do you have any ideas about how to handle Jed's case? Will the MPICH_ATTR_TYPE_TAG_LAYOUT_COMPATIBLE macro (reproduced below) help in this case?<br>
<br>

# define MPICH_ATTR_TYPE_TAG_LAYOUT_COMPATIBLE(type) __attribute__((type_tag_for_datatype(MPI,type,layout_compatible)))<br>
