Abstract
An apparatus having a processor and a circuit is disclosed. The processor generally has a pipeline. The circuit may be configured to (i) detect a first write instruction in the pipeline that writes to a resource, (ii) stall a read instruction in the pipeline where (a) a first read-after-write conflict exists between the first write instruction and the read instruction and (b) no other write instruction to the resource is scheduled between the first write instruction and the read instruction and (iii) not stall the read instruction due to the first read-after-write conflict where a second write instruction to the resource is scheduled between the first write instruction and the read instruction.
