advanced Published 5 Apr 2026
Action Steps
  1. Build a DXIL generator using Go to optimize shader compilations
  2. Run performance tests to compare the results with existing solutions like Rust naga
  3. Configure the generator to produce LLVM 3.7 bitcode for better compatibility
  4. Test the generator with different shader workloads to ensure stability
  5. Apply the generator to real-world applications like games or graphics rendering engines
