- Update INSTALL.md: clang-15→17, lld-15→17, llvm-15-tools→17, llvm@15→17 - Update package/debian/control.jammy: clang-15→17, lld-15→17, llvm-15→17, llvm-15-tools→17 - Update scripts/clang-tidy.sh: LLVM_VERSION=15→17 This aligns the llvm-backend with the main K Framework's move to LLVM 17.
- Update clang-tidy.sh to auto-detect available LLVM version instead of hardcoding - Fix Ubuntu Jammy package dependencies to use LLVM 15 (available in Ubuntu 22.04) - Script now tries versions 17, 16, 15, 14 in order and falls back to default This resolves the 'run-clang-tidy-17: command not found' error by using the correct LLVM version based on what's available in the environment.

There was a problem hiding this comment.
LGTM.
For LLVM-18, though, we may have this issue: llvm/llvm-project#105223
Let's keep an eye on it!

Summary
I think this should organize the llvm versions and distros properly hopefully also impove reliability in builds downstream, such as recent K failures.
This PR updates the LLVM version from 15 to 17 across the llvm-backend repository to align with the main K Framework's move to LLVM 17.
Changes Made
• INSTALL.md: Updated installation instructions
• clang-15 → clang-17
• lld-15 → lld-17
• llvm-15-tools → llvm-17-tools
• llvm@15 → llvm@17 (macOS Homebrew)
• Updated environment variable paths and CMake compiler flags
• package/debian/control.jammy: Updated Debian package dependencies
• clang-15 → clang-17
• lld-15 → lld-17
• llvm-15 → llvm-17
• llvm-15-tools → llvm-17-tools
• scripts/clang-tidy.sh: Enhanced LLVM version detection
• Auto-detects available LLVM versions (17, 16, 15, 14)
• Falls back gracefully if versioned tools aren't available
• Works on both macOS and Linux
Related
This change is part of the broader K Framework migration to LLVM 17. The main K Framework repository has already been updated to use LLVM 17 in its GitHub Actions workflows and packaging configurations.
