echo "WASI Build Status Report"
echo "======================================"

echo ""
echo "Current Status:"
echo "- Successfully configured Node.js build for ia32 target (as wasm32 is not supported)"
echo "- Applied numerous V8 namespace and template fixes"
echo "- Fixed Vector template issues throughout V8 codebase"
echo "- Created WASI compatibility headers (nuclear-fix.h, reglist-wasm32.h)"
echo ""

echo "Major Challenges Encountered:"
echo "1. Node.js does not support wasm32 as a target architecture"
echo "2. V8 JavaScript engine deeply integrated with native CPU architectures"
echo "3. Cross-compilation tools (bytecode_builtins_list_generator, torque) need host compilation"
echo "4. Extensive architecture-specific assembly code in V8"
echo ""

echo "Technical Limitations:"
echo "- Node.js/V8 requires JIT compilation which WebAssembly doesn't support"
echo "- Register allocation and calling conventions incompatible with WASI"
echo "- Platform-specific code throughout V8 (threads, memory management, etc.)"
echo "- Build system (GYP) not designed for WebAssembly targets"
echo ""

echo "What Was Achieved:"
echo "✓ Configured build system for cross-compilation"
echo "✓ Fixed hundreds of namespace and template compilation errors"
echo "✓ Created WASI compatibility layer headers"
echo "✓ Partially compiled V8 base libraries"
echo ""

echo "Recommendation:"
echo "Building Node.js for WASI/WebAssembly requires fundamental architectural changes:"
echo "1. Replace V8 with a WebAssembly-compatible JS engine (like QuickJS)"
echo "2. Use Node.js alternatives designed for WASI (e.g., Javy, wasm3)"
echo "3. Consider using pre-built WASI-compatible runtimes"
echo ""

echo "Alternative Approaches:"
echo "- Use Emscripten to compile Node.js to WebAssembly (different from pure WASI)"
echo "- Use lightweight JS runtimes like QuickJS that support WASI"
echo "- Use container2wasm to run Node.js in WebAssembly containers"

echo "======================================"
echo "Build compilation continues but will not produce a working WASI binary"
echo "due to fundamental architectural incompatibilities."
