The peephole in gen_addsub() rewrote `q + -n` into OP_SUBI n (and `q - -n` into OP_ADDI n) by negating n. For numeric receivers this is equivalent, but for receivers overriding + or - the runtime fallback dispatches the flipped method, losing the original operator. Restrict the fold to non-negative immediates; negative falls through to the normal OP_ADD/OP_SUB path with LOADI of the literal value. close #2557 ref #2579 Co-authored-by: Claude <noreply@anthropic.com>
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.
mrbcexecutable: A command-line tool for compiling.rbfiles into.mrbbytecode 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
