llvm/lib/CodeGen/RegAllocGreedy.h:428: Pointless copy of object ?

[dcb314]

Static analyser cppcheck says:

llvm/lib/CodeGen/RegAllocGreedy.h:428:28: performance: Function parameter 'other' should be passed by const reference. [passedByValue]

Source code is

void add(RAGreedyStats other) {

Suggest new code

void add( const RAGreedyStats & other) {
