Marshal dumps exit locations to the given filename.

Usage:

If --yjit-exit-locations is passed, a file named “yjit_exit_locations.dump” will automatically be generated.

If you want to collect traces manually, call dump_exit_locations directly.

Note that calling this in a script will generate stats after the dump is created, so the stats data may include exits from the dump itself.

In a script call:

at_exit do
  RubyVM::YJIT.dump_exit_locations("my_file.dump")
end

Then run the file with the following options:

ruby --yjit --yjit-trace-exits test.rb

Once the code is done running, use Stackprof to read the dump file. See Stackprof documentation for options.

Starts tracing object allocations.

Stop tracing object allocations.

Note that if ::trace_object_allocations_start is called n-times, then tracing will stop after calling ::trace_object_allocations_stop n-times.

Clear recorded tracing information.

If the SOURCE_DATE_EPOCH environment variable is set, returns it’s value. Otherwise, returns the time that Gem.source_date_epoch_string was first called in the same format as SOURCE_DATE_EPOCH.

NOTE(@duckinator): The implementation is a tad weird because we want to:

1. Make builds reproducible by default, by having this function always
   return the same result during a given run.
2. Allow changing ENV['SOURCE_DATE_EPOCH'] at runtime, since multiple
   tests that set this variable will be run in a single process.

If you simplify this function and a lot of tests fail, that is likely due to #2 above.

Creates a State object from opts, which ought to be Hash to create a new State instance configured by opts, something else to create an unconfigured instance. If opts is a State object, it is just returned.

Returns the string that is used to insert a space before the ‘:’ in JSON objects.

Sets the string that is used to insert a space before the ‘:’ in JSON objects.

Returns true, if NaN, Infinity, and -Infinity should be generated, otherwise returns false.

This sets whether or not to serialize NaN, Infinity, and -Infinity

Generates a valid JSON document from object obj and returns the result. If no valid JSON document can be created this method raises a GeneratorError exception.

Sets the curve parameters. generator must be an instance of EC::Point that is on the curve. order and cofactor are integers.
