From 548757635ce91c8eff3b56480fb4389924e2ea7c Mon Sep 17 00:00:00 2001 From: Zack Hubert Date: Tue, 29 Jul 2025 20:31:20 -0700 Subject: [PATCH 1/5] feat: Implement LLVM-based AOT compilation system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace custom ARM64 assembly generation with robust LLVM-based compilation: - Add SimpleLLVMCodeGenerator using tinygo-org/go-llvm bindings - Support LLVM 20 with proper target initialization and API usage - Generate native object files via LLVM's EmitToMemoryBuffer - Link with system clang for automatic libc integration - Create proper Mach-O executables that run successfully - Test with simple and complex Rush programs Benefits over custom approach: - Cross-platform support (ARM64, x86_64, etc.) - Mature code generation and optimization - Standard system library linking - No more "bad CPU type" or execution issues - Production-ready executable generation 🤖 Generated with [Claude

Install LLVM 18 in GitHub Actions Ubuntu environment - Add LLVM APT repository and development headers - Create symlinks for llvm-config and clang tools - Use -tags llvm18 for both build and test steps ### Build System Improvements - Add build constraints to llvm_simple.go for LLVM versions 14-20 - Create llvm_fallback.go for builds without LLVM support - Provide clear error messages when LLVM is unavailable - Support both LLVM-enabled and fallback builds ### Benefits - ✅ CI builds now work with proper LLVM dependencies - ✅ Local development works with any LLVM version (14-20) - ✅ Graceful fallback when LLVM is not available - ✅ Clear error messages guide users to correct build flags Usage: ```bash go build ./... # Uses fallback (no AOT) go build -tags llvm18 ./... # Uses LLVM AOT compilation ``` 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .github/workflows/go.yml | 15 +++++++++++++-- aot/llvm_fallback.go | 32 ++++++++++++++++++++++++++++++++ aot/llvm_simple.go | 2 ++ 3 files changed, 47 insertions(+), 2 deletions(-) create mode 100644 aot/llvm_fallback.go diff --git a/.github/workflows/go.yml b/.github/workflows/go.yml index 602432e..75d37fc 100644 --- a/.github/workflows/go.yml +++ b/.github/workflows/go.yml @@ -21,8 +21,19 @@ jobs: with: go-version: '>=1.23' + -
