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.
Return the value that should be dumped for the command_line option.
Compile a RationalNode node
Dispatch enter and leave events for RationalNode nodes and continue walking the tree.
Inspect a RationalNode node.
Calculate cursor position in word wrapped content.
Invoked by Ruby’s core methods to run a blocking operation in a non-blocking way.
Minimal suggested implementation is:
def blocking_operation_wait(work) Thread.new(&work).join end
Returns whether the HTTP session is to be kept alive.
Create a new AlternationPatternNode node.
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.
Called before each event with line/column information.
Parse and return a Time from string
Returns a hash of default options used by the Ruby iseq compiler.
For details, see InstructionSequence.compile_option=.
Sets the default values for various optimizations in the Ruby iseq compiler.
Possible values for options include true, which enables all options, false which disables all options, and nil which leaves all options unchanged.
You can also pass a Hash of options that you want to change, any options not present in the hash will be left unchanged.
Possible option names (which are keys in options) which can be set to true or false include:
:inline_const_cache
:instructions_unification
:operands_unification
:peephole_optimization
:specialized_instruction
:tailcall_optimization
Additionally, :debug_level can be set to an integer.
These default options can be overwritten for a single run of the iseq compiler by passing any of the above values as the options parameter to ::new, ::compile and ::compile_file.
Take a location from the prism parser and set the necessary instance variables.
Compose a string representing the given inner location field.
