Efficient breakpoint detection via caches

A computer system, comprising:

• one or more processors;
• and
• one or more hardware storage devices having stored thereon instructions that are executable by the one or more processors to cause the computer system to monitor a memory location for occurrence of a breakpoint through use of a cache during debugging, the instructions including instructions that are executable to cause the computer system to perform at least the following:
• identify a memory address that is to be monitored;
• based at least on identifying the memory address that is to be monitored, perform at least the following:
• store the memory address in a breakpoint monitoring list;
• and
• ensure that any cache lines overlapping with the memory address are evicted from a cache, including, based on the memory address being stored in the breakpoint monitoring list, evicting one or more cache lines from the cache;
• and
• based at least on an indication of an occurrence of a cache miss, determine whether a portion of a cache line imported into the cache based on the cache miss overlaps with the memory address stored in the breakpoint monitoring list, and when the portion of the imported cache line does overlap with the memory address, perform at least the following:
• process one or more monitoring operations on the memory address;
• and
• based on the memory address being stored in the breakpoint monitoring list, evict the imported cache line from the cache.
