* instrumentation: include functions with specific calls Add the option `--caller-include <regex>` or environment variable `OMNITRACE_REGEX_CALLER_INCLUDE` to instrument functions which contain call to a set of functions, E.g. `--caller-include foo` instruments any function which calls `foo`. * Serialize caller include information * Add test for caller include * Tweak to the caller include test - tweak environment - tweak pass regexes * Set rewrite caller example to debug , to avoid optimizing out the call expressions that it relies on.
