System and method for multiple store buffer forwarding in a system with a restrictive memory model

A machine-readable medium having stored thereon a plurality of executable instructions for multiple store buffer forwarding in a system with a restrictive memory model, the plurality of instructions comprising instructions to:

• execute a plurality of store instructions;
• execute a load instruction;
• determine that a memory region addressed by the load instruction matches a cacheline address in a memory;
• determine that data stored by the plurality of store instructions completely covers the memory location in the memory specified by the load instruction;
• and
• transmit a store forward is OK signal.

A processor system, comprising:

• a processor;
• a system memory coupled to the processor;
• and
• a non-volatile memory coupled to the processor in which is stored an article of manufacture including instructions adapted to be executed by the processor, the instructions which, when executed, encode instructions in an instruction set to enable multiple store buffer forwarding in a system with a restrictive memory model, the article of manufacture comprising instructions to:
• execute a plurality of store instructions;
• execute a load instruction;
• determine that a memory region addressed by the load instruction matches a cacheline address in a memory;
• determine that data stored by the plurality of store instructions completely covers the memory location in the memory specified by the load instruction;
• and
• transmit a store forward is OK signal.
