A useful technique for monitoring regressions is to created symbolsort reports and then textually compare them. However symbolsort doesn't have a consistent way of breaking ties in the Sorted by Size section. In a a recent pair of reports on Chrome this led to these two series of globals in the list of symbols:
32768 data gDigits
32768 data nacl_user
32768 data gInvSqrtTable
32768 data nacl_thread_ids
and:
32768 data nacl_thread_ids
32768 data nacl_user
32768 data gInvSqrtTable
32768 data gDigits
The only difference is that the first and last globals are swapped. Using symbol name as a tie-breaker would avoid this problem. I'll probably put together a PR for this later. A couple of swaps is not a problem but on Chrome reports there are typically hundreds.
