That is my experience too.
GCC for code with high level of nesting, meaning high potential for inlining (typically C++), is close to unbeatable. Including even compared Highly optimised compilers like Intel ICC.
- sanxiyn 7y agoLLVM developers are aware of this and they are working on a new inliner specifically to address this.
- earenndil 7y agoIt has not been mine. IME gcc can do slightly better than clang, sometimes, but it's generally a wash.
- sanxiyn 7y agoGoogle found GCC to be faster than Clang for their code, that's why they are rewriting LLVM inliner.
