"summary"=>"\n
We are pleased to announce the release of Ruby 3.3.0-preview1. Ruby 3.3 adds a new pure-Ruby JIT compiler named RJIT, uses Lrama as a parser generator, and many performance improvements especially YJIT.
\n\nRJIT
\n\n- \n
- Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT.\n
- \n
- RJIT supports only x86_64 architecture on Unix platforms. \n
- Unlike MJIT, it doesn’t require a C compiler at runtime. \n
\n - RJIT exists only for experimental purposes.\n
- \n
- You should keep using YJIT in production. \n
\n - If you are interested in developing JIT for Ruby, please check out k0kubun’s presentation on Day 3 of RubyKaigi. \n
Use Lrama instead of Bison
\n\n- \n
- Replace Bison with Lrama LALR parser generator Feature #19637\n
- \n
- If you have interest, please see The future vision of Ruby Parser \n
\n
YJIT
\n\n- \n
- Significant performance improvements over 3.2\n
- \n
- Splat and rest arguments support has been improved. \n
- Registers are allocated for stack operations of the virtual machine. \n
- More calls with optional arguments are compiled. \n
Integer#!=
,String#!=
,Kernel#block_given?
,Kernel#is_a?
,\nKernel#instance_of?
,Module#===
are specially optimized. \n - Instance variables no longer exit to the interpreter\nwith megamorphic Object Shapes. \n
\n - Metadata for compiled code uses a lot less memory. \n
- Improved code generation on ARM64 \n
- Option to start YJIT in paused mode and then later enable it manually\n
- \n
--yjit-pause
andRubyVM::YJIT.resume
\n - This can be used to enable YJIT only once your application is done booting \n
\n - Exit tracing option now supports sampling\n
- \n
--trace-exits-sample-rate=N
\n
\n - Multiple bug fixes \n
