Treating main memory as a collection of tagged cache lines for trace logging

A computer system for treating main memory as a collection of tagged cache lines for trace logging, comprising:

• a processor;
• a main memory;
• a memory cache comprising a plurality of cache lines;
• and
• one or more storage devices having stored thereon executable instructions that, when executed, cause the computer system to at least:
• allocate a plurality of memory blocks within the main memory, including allocating an amount of memory for each of the plurality of memory blocks that is a size of each of the plurality of cache lines;
• allocate a plurality of tags within the main memory, each tag being associated with one of the plurality of memory blocks, each tag indicating whether data stored in its associated memory block has been captured by an execution trace;
• synchronize at least one tag of the plurality of tags within the main memory with at least one cache line tag within the memory cache, including at least one of,
• setting a first cache line tag associated with a first cache line of the plurality of cache lines to a first value, including, based at least on the processor initiating an influx of first data stored in a first memory block of the plurality of memory blocks into the first cache line, i) reading the first value from the main memory, the first value being read from a first memory location within the main memory corresponding to a first tag of the plurality of tags that is associated with the first memory block, and ii) setting the first cache line tag within the memory cache to the first value, or
• setting a second tag of the plurality of tags within the main memory to a second value, including, based at least on the processor initiating an eviction of second data stored in a second cache line of the plurality of cache lines, i) reading the second value from a second cache line tag within the memory cache that is associated with the second cache line, and ii) writing the second value to the main memory, the second value being writing to a second memory location within the main memory corresponding to the second tag of the plurality of tags, wherein the second tag is associated with a second memory block of the plurality of memory blocks;
• and
• manage a traced status of at least one memory block of the plurality of memory blocks within the main memory.
