Make the checks for macro weak symbols be equivalent to the checks for
weak symbols.
Also fix up several OSHMEM configure checks:
* fix an errant AC_MSG_REQUEST
* don't check for profiling ability during configure options checks.
Instead, defer it to later, when we have weak symbol check results.
* don't directly call _FOO macros from the top level
* make setting up OSHMEM profiling similar to MPI profiling: create
OSHMEM_SETUP_PROFILING macro
* cache the results of checking for macro weak symbols (for parity
with the weak symbol check -- although we should really
revisit/audit the whole cache-checking scheme throughout all m4
code; it may well be inconsistently used)
* add some more [] m4 quoting, even in the original C weak symbols test
* style: fix some whitespace errors

Ticket 4868 --> https://svn.open-mpi.org/trac/ompi/ticket/4868
WHAT: Merge the PMIx branch into the devel repo, creating a new
OPAL “lmix” framework to abstract PMI support for all RTEs.
Replace the ORTE daemon-level collectives with a new PMIx
server and update the ORTE grpcomm framework to support
server-to-server collectives
WHY: We’ve had problems dealing with variations in PMI implementations,
and need to extend the existing PMI definitions to meet exascale
requirements.
WHEN: Mon, Aug 25
WHERE: https://github.com/rhc54/ompi-svn-mirror.git
Several community members have been working on a refactoring of the current PMI support within OMPI. Although the APIs are common, Slurm and Cray implement a different range of capabilities, and package them differently. For example, Cray provides an integrated PMI-1/2 library, while Slurm separates the two and requires the user to specify the one to be used at runtime. In addition, several bugs in the Slurm implementations have caused problems requiring extra coding.
All this has led to a slew of #if’s in the PMI code and bugs when the corner-case logic for one implementation accidentally traps the other. Extending this support to other implementations would have increased this complexity to an unacceptable level.
Accordingly, we have:
* created a new OPAL “pmix” framework to abstract the PMI support, with separate components for Cray, Slurm PMI-1, and Slurm PMI-2 implementations.
* Replaced the current ORTE grpcomm daemon-based collective operation with an integrated PMIx server, and updated the grpcomm APIs to provide more flexible, multi-algorithm support for collective operations. At this time, only the xcast and allgather operations are supported.
* Replaced the current global collective id with a signature based on the names of the participating procs. The allows an unlimited number of collectives to be executed by any group of processes, subject to the requirement that only one collective can be active at a time for a unique combination of procs. Note that a proc can be involved in any number of simultaneous collectives - it is the specific combination of procs that is subject to the constraint
* removed the prior OMPI/OPAL modex code
* added new macros for executing modex send/recv to simplify use of the new APIs. The send macros allow the caller to specify whether or not the BTL supports async modex operations - if so, then the non-blocking “fence” operation is used, if the active PMIx component supports it. Otherwise, the default is a full blocking modex exchange as we currently perform.
* retained the current flag that directs us to use a blocking fence operation, but only to retrieve data upon demand

Oops.
This commit is a handful of minor m4 improvements to that original

In core library portions of the configury (e.g., top-level
configure.ac itself), we were calling AC_CHECK_LIB and
OPAL_CHECK_FUNC_LIB to check for various libraries.
'''SIDENOTE:''' It turns out that modern Autoconf has AC_SEARCH_LIBS,
which does just about exactly what OPAL_CHECK_FUNC_LIB does. So this
commit effectively replaces OPAL_CHECK_FUNC_LIB with AC_SEARCH_LIBS.
However, we never bothered to add these found libraries to the wrapper
compiler list of libraries used for static linking (doh!). We've been
getting lucky for quite a while that components were adding the same
libraries to their wrapper compiler LIBS list.
This is problematic, however, if we don't build some of these
components. For example, Paul Hargrove noticed that if he configured
with --disable-shared --enable-static --disable-io-romio, ROMIO was no
longer adding some libraries to the wrapper LIBS list -- libraries
that just happened to also be needed by core OPAL/ORTE/OMPI layers.
The solution is not to use AC_CHECK_LIB or OPAL_CHECK_FUNC_LIB, but
use a pair of new macros:
* OPAL_SEARCH_LIBS_CORE: a wrapper around AC_SEARCH_LIBS. If we add
something to $LIBS, then also add it to the wrapper list of static
libraries. This is the main piece of functionality that was
wrong/missing.
* OPAL_SEARCH_LIBS_COMPONENT: similar to OPAL_SEARCH_LIBS_CORE, but
instead of directly adding it to the wrapper list of static
libaries, add it to <framework>_<component>_LIBS (which eventually
gets slurped up into the wrapper list of static libraries. See the
lengthy comment in config/opal_setup_wrappers.m4 near the beginning
of OPAL_SETUP_WRAPPER_INIT() for a more detailed explanation).
Most components did this correctly already, but one or two weren't
right, so I implemented this second macro quite similar to the
first and put it everywhere we already used AC_SEARCH_LIBS or
OPAL_CHECK_FUNC_LIB.
This needs to soak for a day or two on the trunk before moving to the
v1.8 branch.

WHAT: Open our low-level communication infrastructure by moving all necessary components (btl/rcache/allocator/mpool) down in OPAL
All the components required for inter-process communications are currently deeply integrated in the OMPI layer. Several groups/institutions have express interest in having a more generic communication infrastructure, without all the OMPI layer dependencies. This communication layer should be made available at a different software level, available to all layers in the Open MPI software stack. As an example, our ORTE layer could replace the current OOB and instead use the BTL directly, gaining access to more reactive network interfaces than TCP. Similarly, external software libraries could take advantage of our highly optimized AM (active message) communication layer for their own purpose. UTK with support from Sandia, developped a version of Open MPI where the entire communication infrastucture has been moved down to OPAL (btl/rcache/allocator/mpool). Most of the moved components have been updated to match the new schema, with few exceptions (mainly BTLs where I have no way of compiling/testing them). Thus, the completion of this RFC is tied to being able to completing this move for all BTLs. For this we need help from the rest of the Open MPI community, especially those supporting some of the BTLs. A non-exhaustive list of BTLs that qualify here is: mx, portals4, scif, udapl, ugni, usnic.

ABSoft compilers cannot compile a fortran subroutine

This patch detects this unsupported feature and use

cmr=v1.8.2:reviewer=jsquyres
This commit was SVN r32246.
Older gfortran compilers (e.g., the gfortran that ships in RHEL5) do
not support ISO_C_BINDING, and therefore do not support the
TYPE(C_PTR) type. As such, they cannot support the overloaded
interfaces for MPI_WIN_ALLOCATE_SHARED and MPI_SHARED_QUERY that are
mandated in MPI-3.
So we separate those interfaces out into a separate .F90 file that is
#include'd in the tkr mpi.F90 file. In this separate .F90 file, we
use an #if to determine whether the compiler supports ISO_C_BINDING or
not.
Also re-jiggered the order of testing in ompi_setup_mpi_fortran.m4: we
now need to test whether the compiler supports ISO_C_BINDING even when
we're only building the mpi module (not strictly when we're building
the mpi_f08 module).
Finally, tweaked the use-mpi-tkr/Makefile.am to:
* Add some proper dependencies for mpi.F90
* Allow the general AM compilation to be used instead of supplying a
specific rule for compiling mpi.F90

This is part one of several Fortran improvements and fixes. This
first part removes the now-defunct scripts that are used to generate
the .f90 files in the use-mpi-tkr implementation, and just commits the
output from those scripts. This makes long-term maintenance of the
use-mpi-tkr implementation simpler.

We also split the srcdir/builddir flags according to their local tree (e.g., OPAL_TOP_SRCDIR), and tied them all together in configure.ac. Renamed ompi_ignore and ompi_unignore to be opal_<foo> as these are agnostic markers.
Only thing left is ompilibdir being treated similar to what we dif for srcdir/builddir. Coming soon.
