Retested recently and pragma Volatile caused a compilation issue. Plan to commit the patch add-hpux10-patch.txt if there are no additional suggestions.

However, test results appear similar: http://gcc.gnu.org/ml/gcc-testresults/2012-03/msg01197.html OK, let's use pragma Volatile anyway, it's the closest approximation we have.

On most PARISC machines, reads and writes are strongly ordered and possibly this meets the atomic requirement. Not entirely I think, since the object is 64-bit wide. Of course, it's a little annoying to discover years later that the implementation wasn't really correct. So I'd leave s-taspri-hpux-dce.ads unchanged and just comment out the second pragma Atomic, with a ??? saying that, historically, the pragma had been silently accepted but actually ineffective.

Of course, it's a little annoying to discover years later that the implementation wasn't really correct. It would be inefficient but it would be possible to implement 64-bit atomic loads and stores using floating point double loads and stores. So I'd leave s-taspri-hpux-dce.ads unchanged and just comment out the second pragma Atomic, with a ??? saying that, historically, the pragma had been silently accepted but actually ineffective. I'll give this a try but it will take a while to test. Dave -- John David Anglindave.ang...@bell.net
