SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill ensures the accuracy and consistency of Tcl bytecode generated by a custom compiler by comparing it against the output of the official Tcl interpreter across different versions.

Core Features & Use Cases

  • Bytecode Verification: Compares generated bytecode instructions against reference Tclsh disassembly.
  • Regression Detection: Identifies differences in instruction sequences after compiler modifications.
  • Use Case: After updating the Tcl compiler's code generation logic, use this Skill to run a comprehensive comparison against Tcl 9.0's bytecode to ensure no regressions were introduced.

Quick Start

Run the bytecode comparison skill to get a summary of all snippets against Tcl 9.0.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I verify Tcl bytecode correctness across different interpreter versions?▼

Verify Tcl bytecode correctness by comparing custom compiler output against official tclsh disassembly for versions 8.5, 8.6, and 9.0, analyzing instruction sequences and opcode differences to detect codegen regressions.

What is the best way to detect regressions in Tcl compiler code generation?▼

Detect Tcl compiler codegen regressions by running a bytecode comparison against reference Tclsh disassembly, which identifies differences in instruction sequences and jump encoding after modifying code generation logic.

Can I compare custom Tcl bytecode against official tclsh disassembly for version 9.0?▼

Yes, you can compare custom Tcl bytecode against official tclsh disassembly for version 9.0, analyzing instruction sequences, variable access, and opcode differences to verify codegen correctness.

How do I analyze opcode differences between generated Tcl bytecode and reference disassembly?▼

Analyze opcode differences by comparing custom Tcl compiler bytecode output against official tclsh disassembly, examining instruction sequences, variable access, and jump encoding to verify codegen correctness.

Does Tcl bytecode verification support checking jump encoding and variable access patterns?▼

Yes, Tcl bytecode verification supports checking jump encoding and variable access patterns by analyzing instruction sequences and opcode differences across Tcl 8.5, 8.6, and 9.0 against reference output.

When do I need to run a bytecode comparison for Tcl compiler modifications?▼

Run a bytecode comparison after updating your Tcl compiler's code generation logic to verify bytecode correctness against official tclsh disassembly and ensure no codegen regressions were introduced.
