LLVM vs GNU Compiler Collection : Which is Better?
LLVM
LLVM is a compiler written in C++ designed for compile-time, link-time, run-time, and "idle-time" optimization of programs written in arbitrary programming languages.

LLVM VS GNU Compiler Collection
The GNU Compiler Collection (GCC) is a mature and stable compiler suite known for its excellent support of C/C++ and its robust optimization capabilities. In contrast, LLVM offers a modular architecture that allows for more flexibility, advanced optimization techniques, and support for modern programming languages, making it a better choice for projects requiring rapid development and integration with modern tools.
LLVM
Pros:
- Modular design allows easy extension
- Excellent support for modern languages like Rust and Swift
- Advanced optimization techniques and LLVM IR
- High-quality Just-In-Time compilation
- Fast compilation times due to modular architecture
- Good integration with modern IDEs
- Strong community support and documentation
- Flexibility in targeting different architectures
- Active development and feature additions
- Better support for parallel compilation
Cons:
- Can be complex for beginners
- Relatively new compared to GCC
- Some features may be less mature
- JIT compilation can be less stable than traditional compilation
- Potentially larger binary sizes for some optimizations
- Can have a steeper learning curve for new users
- May lack support for older architectures
- Less straightforward in certain debugging scenarios
GNU Compiler Collection
Pros:
- Mature and stable with a long history
- Wide range of supported languages
- Strong optimization capabilities
- Excellent debugging tools
- Good community support and documentation
- Robust for C/C++ development
- Well-established cross-compilation support
- Comprehensive static analysis tools
- Consistent performance across platforms
- Better error reporting for C/C++
Cons:
- Less flexible for adding new languages
- Lacks support for JIT compilation
- Complexity in integrating with new tools
- Older architecture may lead to slower compilation in some cases
- Limited support for some newer programming paradigms
- Less effective for certain optimizations in non-C/C++ languages
- Larger codebase can lead to longer build times
- May have issues with very new hardware or compilers
