Instruction Cache Management Based on Temporal Locality

A computer-implemented method executed by one or more processors, the method comprising:

• determining that an instruction in a software application indicates that instructions subsequent to the instruction are temporal instructions;
• in response to determining that the instruction in the software application indicates that subsequent instructions are temporal instructions, determining whether the instruction occurred during a nested function call;
• in response to determining that the instruction occurred during a nested function call, determining to store future cache entries as non-temporal cache entries instead of temporal cache entries;
• and
• storing a cache entry for an instruction subsequent to the instruction as a non-temporal cache entry instead of a temporal cache entry.

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• determining that an instruction in a software application indicates that instructions subsequent to the instruction are temporal instructions;
• in response to determining that the instruction in the software application indicates that subsequent instructions are temporal instructions, determining whether the instruction occurred during a nested function call;
• in response to determining that the instruction occurred during a nested function call, determining to store future cache entries as non-temporal cache entries instead of temporal cache entries;
• and
• storing a cache entry for an instruction subsequent to the instruction as a non-temporal cache entry instead of a temporal cache entry.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• determining that an instruction in a software application indicates that instructions subsequent to the instruction are temporal instructions;
• in response to determining that the instruction in the software application indicates that subsequent instructions are temporal instructions, determining whether the instruction occurred during a nested function call;
• in response to determining that the instruction occurred during a nested function call, determining to store future cache entries as non-temporal cache entries instead of temporal cache entries;
• and
• storing a cache entry for an instruction subsequent to the instruction as a non-temporal cache entry instead of a temporal cache entry.
