AMD x86-64 processors cannot predict single-byte near RET instructions when they are either the target of a branch or immediately preceded by a conditional branch. (See section 6.2 in the Athlon 64/Opteron optimization guide)AMD's recommended solution is to either reorder instructions so that this situation does not occur, or use the REP prefix on the RET instruction.
