Yukihiro "Matz" Matsumoto 42cea9d3ee mruby-compiler: optimize JMPNOT+JMP to JMPIF in alternative patterns

In alternative patterns (e.g., `Integer|String`), when the left pattern
has a single JMPNOT immediately before the JMP to success, convert the
JMPNOT to JMPIF and eliminate the JMP instruction.

This saves 3 bytes per optimized alternative pattern.

mruby-compiler

This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.

Functionality

The mruby-compiler gem includes the following components:

Parser: Translates Ruby source code into an abstract syntax tree (AST).
Code Generator: Traverses the AST to produce executable mruby bytecode.
mrbc executable: A command-line tool for compiling .rb files into .mrb bytecode files.

Usage

The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby programs via this gem.

Example of using mrbc:

# Compile a Ruby script to bytecode
bin/mrbc my_script.rb

# Run the compiled script
bin/mruby my_script.mrb
