🤖 Compiler & Build Configuration

Toolchain

• Clang: ZyCromerZ Clang 19.0.0git (Oryon-optimized)
• Linker: LLD 19 with ThinLTO cache in RAM (/dev/shm)
• CCache: ECS-enhanced ccache with 10GB cache + aggressive sloppiness

Compiler Flags

-O2                          # Balanced optimization level
-mcpu=oryon-1               # Target Snapdragon 8 Elite cores
-fno-strict-aliasing        # Safer pointer aliasing
-fno-delete-null-pointer-checks  # Extra null safety
-flto=thin                  # ThinLTO for link-time optimization (optional)
-ffile-prefix-map=...       # Reproducible builds

🛠️ Build Workflow (GitHub Actions)

Quick Start

1. Fork this repository (ensure all branches are copied)
2. Go to Actions → Enable workflows
3. Click "SukiSU Ultra OP13 Build" → "Run workflow"
4. Configure options:
   • ✅ SuSFS (recommended for hiding)
   • ✅ Fengchi (performance scheduler)
   • ✅ Memory Opt Patches (25 optimizations)
   • 🔘 LTO Type: thin (balanced) / none (fastest compile) / full (max optimization)
   • 🔘 Optional features: KPM, LZ4KD, NTSync, IPv6 NAT, etc.
5. Click "Run workflow" → Wait ~4-5 minutes
6. Download AnyKernel3_*.zip from artifacts or Telegram

Workflow Optimizations

This CI pipeline includes:

• 🚀 Parallel patch application for 20+ WildKernels patches
• 💾 RAM-based LTO cache (/dev/shm) to avoid disk I/O bottlenecks
• ⚡ ThinLTO job limiting (--thinlto-jobs=$(nproc/2)) to prevent CPU thrashing
• 🔄 Aggressive ccache with kernel-specific sloppiness for maximal cache hits
• 📦 Pre-downloaded toolchain via aria2c with 16 connections
• 🗑️ Background cleanup of unused GitHub runner packages

Build Time Expectations with CCache

Configuration	Estimated Time
lto_type: none + minimal patches	~3:20-3:50
lto_type: thin + all patches (default)	~4:50-5:50
lto_type: full + all patches	~7:00-9:00

💡 Tip: Use lto_type: none for rapid testing, thin for release builds.
