This commit removes alpha asm support. No current processor
manufacturer makes chips compatible with DEC alpha and no
participating organization has alpha processors. This makes it
difficult to support alpha via assembly.
This doesn't mean Open MPI will no longer build/work on alpha
processors. It should continue to work with gcc's builtin sync
atomics.

Use of this configuration option can cause crashing, hanging, and
(worse) incorrect results when btl/sm, btl/scif, or btl/vader are
in use. We discussed this at the January 2015 developers meeting
and it was decided to remove the option entirely. This commit does
just that. All usage of OPAL_WANT_SMP_LOCKS has been removed.
Also, since I put some of the macros for these silent/verbose rules up
in the top-level Makefile.man-page-rules file, I renamed it to
Makefile.ompi-rules.
I've had this sitting around for a while; now seems like as good a
time as any to commit it.

Since Paul is the only one of the team with the required hardware to test it, and he has done so, consider this RM-approved.

Leif would like to revamp the ARM support in a different way, and will
submit a patch to do so in the future.

* The opal_sys_timer_get_cycles() call was implemented for
Sparc v9 using inline assembly, but not in the assembly files.
This would only currently matter on Linux Sparc systems using
a compiler that didn't support inline assembly (not many of
those), but it should be there for completion.
* The linux timer component would always build on non-Alpha
platforms, rather than only building on platforms where
opal_sys_timer_get_cycles() was implemented. This would
only matter on a very narrow set of platforms that we don't
really support, but still, it could be more right. We now
only build the component on platforms where we have the
assembly call to get the cycle counter.
* Added a comment to opal/sys/timer.h to note that the linux
timer component needed to be updated if another platform was
added.
This should be harmless to commit. It will only really change
behaviors on platforms we don't have assembly support for, which
currently won't make it through configure. It really only matters
when (if?) we support atomic operations through libatomic_ops.

there is an exit path out of the loop
* Reformat assembly to match other platforms
* Update base file for non-inline assembly to match changes in
the inline version
This commit was SVN r11803.
* Use $31 instead of mnemonic zero for the gcc inline
assembly test, as the GNU assembler doesn't like
zero, but both Tru64 and GNU assembler should be fine
with $31
* Disable Linux timer component on Alpha. The CPU timer
rolls over every 10 seconds or less, so it's kinda
worthless for our needs.
* Fix some escaping issues when local functions are
denoted with a $
* Remove C++ comments from the Alpha assembly.
* Add base assembly code for the non-inlined functions
on Alpha

to the compiler not to reorder memory-related instructions. The
IA64 instruction for memory barriers is "mf".
Fixes bug #137.

as I understand how that one works and don't really understand what
was in the amd64 code (which was copied from before I started working
on the inline assembly). This fixes the race condition we were
seeing on PGI causing test failures
* sync non-inline assembly with inline assembly version
This needs to go to the v1.0 branch

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)
This commit was SVN r8985.
- don't fail to configure if threads aren't found, since
we don't have thread support on windows
- rather than setting the asm file name to none in asm-data,
special case windows w/ CL in the ompi_config_asm macros.
Otherwise, there were some warnings during make dist and
configure that didn't need to be there.
This commit was SVN r8502.
- add the right asm format
- add checks for some constants / fields that cygwin
doesn't have in the stacktrace code
- fix for slightly more verbose libtool 2 betas that
have multiple lines for link output
