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.

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.
The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.
Add a list of paths to the $LOAD_PATH at the proper place.

Negate the value of a numeric node. This is a special case where you have a negative sign on one line and then a number on the next line. In normal Ruby, this will always be a method call. The parser gem, however, marks this as a numeric literal. We have to massage the tree here to get it into the correct form.
Within the given block, track that we’re within a pattern.
Parse a float from the string representation.
Parse a rational from the string representation.
Enables use of shared session key material in accordance with RFC 5705.
Returns true if key is the corresponding private key to the Subject Public Key Information, false otherwise.
Serializes the private key to DER-encoded PKCS #8 format. If called without arguments, unencrypted PKCS #8 PrivateKeyInfo format is used. If called with a cipher name and a password, PKCS #8 EncryptedPrivateKeyInfo format with PBES2 encryption scheme is used.
