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.
Like Enumerable#reject, but chains operation to be lazy-evaluated.
Like Enumerable#grep, but chains operation to be lazy-evaluated.
Like Enumerable#grep_v, but chains operation to be lazy-evaluated.
Rewinds the enumerator chain by calling the “rewind” method on each enumerable in reverse order. Each call is performed only if the enumerable responds to the method.
Rewinds the product enumerator by calling the “rewind” method on each enumerable in reverse order. Each call is performed only if the enumerable responds to the method.
Reset the digest to its initial state and return self.
Reset the digest to the initial state and return self.
Free this closure explicitly. You can’t use this closure anymore.
If this closure is already freed, this does nothing.
Whether this closure was freed explicitly.
Create a new closure. If a block is given, the created closure is automatically freed after the given block is executed.
The all given arguments are passed to Fiddle::Closure.new. So using this method without block equals to Fiddle::Closure.new.
Fiddle::Closure.create(TYPE_INT, [TYPE_INT]) do |closure| # closure is freed automatically when this block is finished. end
Return the object that this pinned instance references.
Returns true if the reference has been cleared, otherwise returns false.
Or read the memory at address address with length len and return a string with that memory
Set the free function for this pointer to function in the given Fiddle::Function.
Get the free function for this pointer.
Returns a new instance of Fiddle::Function.
Returns if the free function for this pointer has been called.
Returns a new Fiddle::Pointer instance that is a reference pointer for this pointer.
Analogous to the ampersand operator in C.
Fully resets the internal state of the Cipher. By using this, the same Cipher instance may be used several times for encryption or decryption tasks.
Internally calls EVP_CipherInit_ex(ctx, NULL, NULL, NULL, NULL, -1).
Resets the Digest in the sense that any Digest#update that has been performed is abandoned and the Digest is set to its initial state again.
Returns hmac as it was when it was first initialized, with all processed data cleared from it.
