Types are translated from C to Fortran where applicable, though currently only for MPI_INT -> MPI_INTEGER, MPI_DOUBLE -> MPI_DOUBLE_PRECISION, MPI_C_BOOL -> MPI_LOGICAL as most Fortran MPI types are optional.
Tests are formatted using fprettify (available from pip, added to Pipfile).
Common Issues encountered:
MPI does not differentiate between bool and int, but does between integer and logical.
Workaround: Use bool where applicable in C code, then translate to logical
Different integer size expectations cause compilation failures (no automatic extension)
Workaround: During parsing of apis.json, save the integer width, and perform explicit widening if needed.
C usage of address-of-integer as a one-dimensional array does not work in Fortran
Workaround: Replace uses thereof with proper arrays
Array Indexing starts at 1
Workaround: Implement explicit indexing to match C
MPI-BugBench bugs (since remembering to write them down):
Deadlock in CallOrdering-mpi_improbe-mpi_send-001, wrong parameter used as flag
Note: Deadlock also happens in InvalidParam-flag-mpi_iprobe-002, but intended? (not_allocated flag is not waited on, but the "normal" one)
