SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents LLVM test workflows from stopping unnecessarily when lit or FileCheck is missing from the current shell.

Core Features & Use Cases

  • Tool Discovery: Locate lit and FileCheck in the active environment or an existing LLVM workspace.
  • Failure Diagnosis: Distinguish missing test-tool availability from genuine PTOAS test or regression issues.
  • Use Case: When a PTOAS test command reports that lit or FileCheck cannot be found, use this Skill to identify usable LLVM-provided tools before investigating the repository.

Quick Start

Use the LLVM test tool fallback skill to locate lit or FileCheck and continue the PTOAS test workflow.

Frequently Asked Questions about llvm-test-tool-fallback

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

FAQPage Schema
Why does my lit test workflow fail with a missing FileCheck error?

You can locate lit and FileCheck by searching the active environment or an existing LLVM workspace for usable tool installations. This identifies the correct LLVM-provided tools before you investigate the repository for regressions.

How do I distinguish a missing LLVM test tool from a PTOAS regression?

You distinguish a missing LLVM test tool from a PTOAS regression by verifying if lit or FileCheck is installed in your active environment. If the tools are missing, the failure is an environment issue, not a repository regression.

Can I find LLVM test tools in an existing workspace if they are missing from my shell?

Yes, you can find LLVM test tools in an existing workspace if they are missing from your shell. The tool discovery process searches active environments and LLVM workspaces to locate usable lit and FileCheck installations.

What's the best way to fix lit or FileCheck not found in PTOAS test scenarios?

The best way to fix lit or FileCheck not found in PTOAS test scenarios is to search the active environment for usable LLVM-provided tool installations. This allows the test workflow to continue without investigating the repository.

Does this approach work for both lit and FileCheck discovery in LLVM environments?

Yes, this approach works for both lit and FileCheck discovery in LLVM environments. It locates either tool so lit or FileCheck-based workflows can continue when test commands report missing dependencies.
