|
common blocks in the Fortran equivalents. See
|
|
ompi/mpi/f77/constants.h for a more detailed explanation.
|
|
|
|
The values are *NOT* initialized. We do not use the values of
|
|
these constants; only their addresses (because they're always
|
|
passed by reference by Fortran).
|
|
|
|
Initializing upon instantiation these can reveal size and/or
|
|
alignment differences between Fortran and C (!) which can cause
|
|
warnings or errors upon linking (e.g., making static libraries with
|
|
the intel 9.0 compilers on 64 bit platforms shows alignment
|
|
differences between libmpi.a and the user's application, resulting
|
|
in a linker warning). FWIW, if you initialize these variables in
|
|
functions (i.e., not at the instantiation in the global scope), the
|
|
linker somehow "figures it all out" (w.r.t. different alignments
|
|
between fortan common blocks and the corresponding C variables) and
|
|
no linker warnings occur.
|
|
|
|
Note that the rationale for the types of each of these variables is
|
|
discussed in ompi/include/mpif-common.h. Do not change the types
|
|
without also modifying ompi/mpi/f77/constants.h and
|
|
ompi/include/mpif-common.h.
