Which compiler is better for performance: GCC or Clang?

Which compiler is better for performance: GCC or Clang?

Both GCC and Clang have their strengths. GCC is known for its optimization in certain scenarios, while Clang often provides faster compile times and better diagnostics.

Can you give examples of scenarios where one outperforms the other?

Sure! GCC tends to excel in large codebases and complex optimizations, while Clang is often preferred for projects that require rapid iteration and debugging.

What about the support for different architectures?

GCC has broader support for various architectures, especially older ones. Clang, however, is catching up and offers excellent support for modern architectures.

Is there a significant difference in the generated binary size?

Yes, there can be differences. GCC may produce smaller binaries in some cases, while Clang can generate larger binaries due to its debugging information.
