I created some SMP safe osi atomic operator functions (increment, decrement,
etc) on the CVS main trunk - which were not included in the Bazaar main
trunk (which is branch off of R3.14). I mentioned these functions briefly in
my talk at the last EPICS meeting. The implementation is based on the resent
GNU compiler intrinsic functions, and when that compiler isn?t available is
based on OS primitives. Old vxWorks 68k doesn?t need anything special as its
increment function is atomic. The PPC vxWorks can just use intLock. SMP
vxWorks has the new gcc. RTEMS probably will also. I have implementations
also for Solaris and MS WIN32.
