描述

I am currently using google/benchmark to benchmark https://github.com/protocolbuffers/upb. I would very much like for those benchmarks to also include memory usage.

Does this project support memory benchmarking? The user guide does not mention memory usage benchmarking at all. However I notice that the header has a RegisterMemoryManager() function, and there is a unit test verifying this functionality.

From running the test, it appears that the memory usage data is surfaced to JSON, but not CSV or console reports. Is this an oversight or intentional? Ideally this data would be shown on CSV and console reports also.

研究方向
Investigate the benchmark output formatters to understand how memory data is currently emitted in JSON. Then implement changes to include memory usage in CSV and console output formats. Look at benchmark.h for RegisterMemoryManager and test/memory manager test.cc for reference. Ensure the new output is consistent with existing report structure.
