Techniques are disclosed involving operand management using a fusion buffer. A processor includes operand management circuitry, where the operand management circuitry includes a fusion buffer, and execution circuitry. In one embodiment, the operand management circuitry is configured to detect a first storage instruction operation that is executable to store operand values usable by one or more consumer instruction operations and store the first storage instruction operation in the fusion buffer. In response to detecting a drop condition associated with the first storage instruction operation, the operand management circuitry is configured to remove the first storage instruction operation from the fusion buffer without forwarding the first storage instruction operation for execution. In response to detecting a buffer vacate condition and not detecting the drop condition the operand management circuitry is configured to forward the first storage instruction operation for execution by the execution circuitry.
