openmpi/test/asm/atomic_cmpset_64_serial.c
Brian Barrett 4b6aecf82d * Fix up the test directory so everything uses Automake's "make check" to
build / run.  Only things that actually build / run right now are the
  asm and class tests.  The mca tests probably will with a static build
  but that hasn't been verified
