Functions

ever_symbolized

Check whether symbolization has ever been run in this process. This controls whether we display a warning about increasing RAM usage due to the backtrace cache on the profiler page. (Because the RAM hit is one-time, we don’t need to warn if it’s already happened).

symbolize

Given some stack traces, generate a map of addresses to their corresponding symbols.
