atomics.patch
Description: Binary data
A problem Siegmar reported on trunk over a year and a half ago is breaking a 32-bit build of the v1.8 branch with the Sun C++ compiler:
There are several warnings, but the error is (from my current build):
"/shared/OMPI/openmpi-1.8-latest-solaris11-x86-ib-ss12u3/openmpi-1.8.2rc4r32480/ompi/mpi/cxx/ file.cc", Error: The function opal_atomic_add_32(volatile int*, int) has not had a body defined.
It applies cleanly to v1.8 but appears to make things worse, trading that one error for two:
"/shared/OMPI/openmpi-1.8-latest-solaris11-x86-ib-ss12u3/openmpi-1.8.2rc4r32480/opal/include/opal/sys/atomic_impl.h", line 106: Error: opal_atomic_add_64(volatile long long*, long long) was previously declared "extern", not "inline".
"/shared/OMPI/openmpi-1.8-latest-solaris11-x86-ib-ss12u3/openmpi-1.8.2rc4r32480/opal/include/opal/sys/atomic_impl.h", line 121: Error: opal_atomic_sub_64(volatile long long*, long long) was previously declared "extern", not "inline".
The good news is that the problem does not exist on the trunk. So, hopefully somebody can track down the proper changes to CMR.
