I hope you are aware, that *many* tools and application actually
profile the fortran MPI layer by intercepting the C function calls.
This allows them to not have to deal with f2c translation of MPI
objects and not worry about the name mangling issue. Would there be
a way to have both options e.g. as a configure flag? The current
commit basically breaks all of these applications...
I was unaware of this, actually.
So it'd be pretty easy to have a configure switch for this (it would
be a bunch more work for a run-time switch; I don't know if it's
really worth it?). Should we default to the current behavior, and
have the configure switch enable call stacks like this:
MPI_Comm_rank_f
PMPI_Comm_rank_f
PMPI_Comm_rank
?
