We've used -O2 for x86_64 since: 6f335e555da5c14e43d3fdaeb90bcecc80ea4272 "2006/03/06 11:47:01 kendy 1.5.76.1: #i62814# x86-64: -O2 instead of -Os for the optimized builds" x86 was -Os back then, and still is. The rest of the platforms using -Os are probably just cnp or a general vague feeling that -Os is a good choice for limited hardware.
