Anyway, this is blocking the move: do not include pml.h
if not really needed, aka none of the following used:
mca_pml
MCA_PML_CALL
OMPI_ANY_TAG
OMPI_ANY_SOURCE
OMPI_PROC_NULL
- Notable exceptions (deleting in one header->adding):
- ompi/mca/mtl/psm/
- ompi/mca/osc/rdma/
- ompi/mca/btl/openib/btl_openib_endpoint.c depended on
pml_base_sendreq.h
- Tested on Linux/x86-64, this time including make check
(thanks Jeff and Ralph)
This commit was SVN r20725.
