About:
Mold is a high-performance linker designed for speed, capable of linking large C++ projects many times faster than traditional linkers like GNU ld or gold. It achieves this through a modern, parallel architecture that efficiently utilizes multi-core processors. The tool is optimized for developer productivity, drastically reducing build times during the development cycle.
Key Features:
  • Extremely fast linking speeds (10x-100x faster than GNU ld)
  • Parallel processing capabilities
  • Compatibility with GNU ld command-line options
  • Supports x86-64, ARM, and other architectures
Use Cases:
  • Accelerating build times for large C++ projects
  • Reducing iteration time during software development
  • CI/CD pipeline optimization
Alternatives:
  • GNU ld – Mold is significantly faster but offers similar functionality for standard linking tasks
  • LLD – Mold is generally faster than LLD, though LLD is also a high-performance alternative to GNU ld
