SVN rev 209790 on 2010-07-08 03:41:57Z by lstewart
MFC r209119,209325:
- Add a utility macro to simplify calculating an aggregate sum from a DPCPU
counter variable.
- Rename the internal for loop iterator to "_i" to avoid potential shadowing of
external variables named "i". The "_" prefix is reserved for infrastructure
type code and is therefore not expected to be used by normal code likely to
call DPCPU_SUM(). [1]
- Change DPCPU_SUM to return the sum rather than calculate and assign it
internally. Usage is now: "sum = DPCPU_SUM(dpcpu_var, member_to_sum);" [2]
- Fix some style nits. [3]
