Comment #11 is also true for Yi SSE registers (for TARGET_INTER_UNIT_MOVES targets, i.e. -march=core2). Under integer register shortage, allocator will start to allocate SSE registers, and reload will later generate various xmm->reg moves to satisfy subsequent instruction constraints. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37364
